Toshiba Tecra 8100. How to remove and replace FL inverter board.
Use Toshiba Tecra 8100 display disassembly guide to remove and replace the FL inverter board. If the backlight on your computer suddenly stopped working but you still can see a faint image, then most likely the problem is caused by a failed FL inverter board. Before you jump in and start buying hardware make sure to read through laptop video problem tips. Be very careful with the LCD screen mask. The plastic is very fragile and can be easily broken. Use only your finger when you remove the LCD mask. Do not use a screwdriver or any other sharp object because you can damage the screen.
You can use the same FL inverter board for 13″ screen and 14″ screen. Toshiba part number for the FL inverter: P000272240

Thanks for all the great tutorials. I was wondering if you could do a complete disassembly of a Tecra 8100? I need to find the RPC battery and it has elluded me.
Thanks.

Hey Jason,
I haven’t created a disassembly guide for this model yet. Here is a link to Toshiba Tecra 8000 FRU documentation. This .pdf file is 2.7MB, so if you have a slow connection it can take some time to open it. I hope this FRU documentation will help you to replace the RTC battery.

Thank you for the link. I think that may contain the info I need. I really appreciate it.

Hi truong,
I do not have Toshiba Tecra 8100 motherboard schema. Sorry cannot help.
April 23rd, 2006 at 2:21 pm
Thanks for the great site you have.
I have problem with hinges., they start to be loosing LCD holding.
Is any chance to tighten them?
April 23rd, 2006 at 10:05 pm
Mike,
If the hinges are not broken, you can tighten them. What laptop model do you have? Check out my Toshiba laptop disassembly guides for your laptop model.
May 5th, 2006 at 9:11 pm
It’s Tecra 8100, any specific insruction how to do this?
I’m kinda afraid to break LCD screen mask, this is my first time to deal with laptop repair.
May 8th, 2006 at 5:39 pm
cj2600, great guides!
Do you by any chance know the part numbers of the tecra 8100 display hinges? I need to replace a bit that holds the shaft of the hinge “from the LCD side”. It is a small rectangular bit (less than 1″x1″) in the LCD, and is clearly visible in the bottom-right corner of the LCD on your photo “remove-replace-FL-inverter-06.jpg”.
May 8th, 2006 at 11:06 pm
Max,
On this model the hinge has 2 parts. One part is connected to the side of the LCD screen (part1). Second part is connected to the laptop base (part2). On the step 6 the part 1 is located above the part 2. The screw goes through part 1 into part 2.
I believe you are talking about part 2 – the hinge itself.
Toshiba Satellite 8100 with 14 inches screen. Part numbers for the right side:
Part 1 (screwed to the side of the LCD screen)
P000288940 for Toshiba, Sharp and Samsung displays
P000300630 for Hitachi display
P000303430 for Chimei display
Part 2 (the hinge itself)
P000294150 or P000309040 for Toshiba, Sharp and Samsung displays
P000307010 or P000311310 for Hitachi or Chimei displays
May 9th, 2006 at 4:07 pm
cj2600, you rule! Great thanks!
PS. Is this info available publicly, or one has to have inside ways with Toshiba to get the information?
May 9th, 2006 at 9:14 pm
Max,
This information is not available publicly; at least I do not know any source to get it. You have to be a Toshiba certified technician to get an access to this info.

Hi,
I am using tecra 8200. my son finished watching Video with it and i shutdown the system when i reboot the system the next day it came on but nothing showed on screen. But other signs shows the system is booting proper except the blue screen that appears and i could not see the boot process. What should i do to get my system back normally. Pls. direct me i need help
May 24th, 2006 at 10:12 pm
TGonline,
You say nothing appears on the screen and then mention a blue screen. Is it BSOD- blue screen of death? Please give more details. Try to hook up an external monitor and turn on the laptop, see if you can get any video on the external monitor.
This thread about troubleshooting laptop video problems might be helpful for you.

Hi,
thank you very much for your info about the inverter board. My Tecra 8100 had the discribed problem and I even took it to a professional workshop (don’t know if this is the right word
without result. Then I found your site and VoilĂ : After disconnecting and reconneting the inverter board everything works fine. So again – thank you!!

how do you get the processor out i want to upgrade it
August 21st, 2006 at 10:46 pm
Joe,
I haven’t created a guide for taking apart Tecra 8100 yet. Check out comment 2. It has a link to Tecra 8000 FRU. It might help.
September 1st, 2006 at 4:30 am
hi i have a tecra 8100. when i play dvd´s the screen fades after a short time i have a 8200 from a freind witch worked until he droped it i think the motherbord is cracked and i was wondering if i could replaces the parts with my 8100.thanks
September 2nd, 2006 at 11:50 pm
Andrew,
I guess it depends on the part you want to replace. If you give me more information about 8100 and 8200 laptops (model number) and tell me what part you want to use, I would check if these parts are interchangeable.
October 4th, 2006 at 10:29 am
I replaced the FL INVERTER for my tecra 8100, however the fault has reappeared after several months.
do i need a specific version or revision?
and does anyone know of a reliable source in UK
October 18th, 2006 at 6:20 pm
I have a Toshiba Techra 8100. Its been working fine. All of a sudden it wont start up and a yellow flashing light which shows a plug in blinks plugged in or not. On the docking station or not! It wont do anything. Over night I was able to start it up this am and I am back to the same thing today any ideas would be greatly appreciated! Paul
October 18th, 2006 at 6:21 pm
PS it is plugged in!
November 9th, 2006 at 8:34 am
It seems alot of people are having problems with the hinges… I just acquired my Tecra 8100 for free, and the screen is kind of floppy… about 5 inches of play. It stays up but it’s kind of weak. Also, I can hear something rattling around. I assume it’s a broken hinge? I’ll remove the mask today to see. Great article.
November 24th, 2006 at 11:35 pm
Hello cj2600,
This is in reference to the hinges that you labeled as Part 2 in comment #10. I would like to please find out if there is a guide that shows how to take apart the base of a Toshiba Tecra 8100 or if you could describe it so I can replace those hinges (Part 2). Apparently, Part 2 can only be accessed either underneath the keyboard or from the bottom.
Thank you very much.
November 27th, 2006 at 12:57 am
Miagi,
I don’t have a guide for this particular model. If you want to replace hinges, you’ll have to open up the laptop and remove the top cover. You can find my disassembly guides for other models here, in general they all share the same steps. Read through a few guides and you’ll see how to remove the top cover from your laptop.
December 2nd, 2006 at 7:17 pm
Hello CJ2600!
I was wondering if you could do the complete disassembe the Toshiba Tecra 8100 laptop.
I was wondering how to do that.
Thanks in advance.
December 11th, 2006 at 3:54 am
Great article!
Tecra 8200, screen blinked when moving lid. After disassembly (thanks for instructions) and reconnecting inverter everything works fine.
Thanks!

I have a Toshiba Tecra 8100, with 256mb of RAM, 20Gb of Hdd, 750Mhz Processor & Dvd Rom. i have trouble with my notebook sometimes if i turn on it the LCD is blank, n sometimes it’s working, but the really problem is more slowly then before, very slowly. Please help me to troubleshoot this problem
April 11th, 2007 at 12:54 am
This is one great article I was looking since ages. I have a Tecra 8100 and FL Inverter blacking out is exactly the problem I face. Today, I’ll remove and reconnect the FL Inverter and see if it works.
April 16th, 2007 at 12:19 am
Thank you very much buddy… for this very very very helpful guide. I disconnected my FL inverter and reconnected it and it is working fine now. Earlier, I used to experience screen black-outs very very frequently. But now there are none. I don’t know what will happen in future, but as of now, (I have been testing my LCD on Toshiba Tecra 8100 since two days, and there is not even one instance of screen black-out till now. Thank you for a great tutorial.
Thank you once again
April 19th, 2007 at 1:09 pm
Thank you. Fl inverter tube was removed, sprayed with anti oxidant spray, then re connected. Works wonderfully! Thank you!
I would like to note there is alot of heat from the Fl inverter and would like to make vent holes and possibly add a heat sink for as a DIY project.
I also plan to clean dust, dissasemble, and upgrade cooling.
More information would be great.

Hi! This is a great site. I used your guide from the 8200 to begin dismantling my 8100. Thanx.
I have trouble finding info on my problem: could you push me in the right direction?
I replaced my 5gb hd to a 40gb hd (temporarily without screws) and all worked well (I cloned it). But I pulled out the drive (actually when it was still shutting down, possibly) and reinstalled it with screws. Now, no boot…no screen, no post, not even a fan spins. The hd lite comes on for a few seconds, barely active (red & green?), then amber lite.
This sounds textbook mistake…but what is broken? MB? Reset MB?
any help is welcomed. Thanx.

MY LAPTOP TECRA 8100 THE VIDEO IMAGE VERY FAINT HOW MUCH IS THE FL INVERTER PART NO POOO272240 I HAVE LEARNT ABOUT THIS THROUGH THIS FORUM I TRIED TO OPEN TRYING TO SEE IF THERE IS A BULB INSIDE I COULD NOT SEE IT COZ IT IS SEALED WHEN TRIED TO PUT BACK NO FAINT IMAGE WHICH WAS THERE BEFORE PLEASE HELP WHAT COULD BE A FAULT AGAIN
September 8th, 2007 at 7:08 am
Excellent website. I have a Toshiba Tecra 8100 with the same problem. The screen was going very faint very frequently, after a while even pressing the pin when the lid closes it wouldn’t come back…
I ordered the part POOO272240, installed it and now it seems to work fine.
Thanks a lot,
Max
September 17th, 2007 at 9:12 pm
max, where did you order part no. POOO272240?
September 17th, 2007 at 9:34 pm
max,
I guess that’s why you cannot find it.
Just Google for P000272240. Note the all “O” in the part number are actually “0″ (zeros).
September 30th, 2007 at 12:55 pm
Back in post #10, cj2600 gave info and part #’s for hinge problems on the Tecra 8100. I’m having those same issues with my Tecra 8000 (14″ screen). Any part #’s, advice on fixing, and so on would be much appreciated!
November 30th, 2007 at 10:35 am
Thank you. I have successfully replaced the FL inverter board by following your instructions. However, something odd is happening: the new board fails (the backlighting switches off repeatedly, as before) if I put the screen mask back on. I have checked the old inverter, which fails either with the mask on or off.
I think this must be a matter of temperature or pressure exerted by the mask on the board, but this didn’t happen before. Any suggestions?
December 30th, 2007 at 5:00 pm
Thanks for the instructions. They were very useful!
Two other things that inexperienced DIY-ers might want to know:
1) Note the tabs that hold the screen mask in place. (Can sort of see these on the “remove screen mask” photo.) Pushing or prying in these areas with a thumbnail can help pop the screen mask off. (From the outside, not the screen side!)
2) Note places where wires, etc. can cover tabs when re-installing inverter. Carefully tuck the inverter back in underneath its plastic cover.
Our inverter had been replaced before without attention to these tabs, making it difficult to get the screen mask off again without damaging it. There are pinch points near the hinges, specifically.
Has anyone succeeded in improving the cooling? One comment suggested drilling holes or cleaning things… did it work?
Thanks,
Erica

I bought a Tecra 8100 with the same problem: screen turned faint frequently after 5 min. However, I did not change the inverter. From a web, I got an information that you just need to pull out and plug in the power connector to the inverter for five times. It is quite unbelievable but I tried and it worked like a charm. Five months have passed the computer has worked perfectly.
April 30th, 2008 at 7:17 am
Excellent instruction and guidance – thanks! Your info quickly solved 2 frustrating problems with my wife’s Tecra 8100 (intermittent LCD backlight and a loose lid), thereby postponing the cost of a replacement and restoring marital harmony!
But 1 issue remains. When returning from standby, a “resume failure” error frequently (but not always) occurs, forcing a system reboot. Any ideas of what’s going on here? Marginal RAM maybe? BTW, battery condition is fine. I ended up disabling standby and forcing hibernation instead, but it’s not ideal.
Any help would be much appreciated!
Cheers,
Mike C.

Mike C,
First of all thank you for your generous donation to http://www.irisvista.com
Now regarding your problem.
There is no simple answer but I would definitely run diagnostic tests on memory and hard drive.
For testing memory you can use Memtest86+.
For testing the hard drive you can use Hitachi’s drive fitness test.
I linked to both utilities in “Useful Links” on the right side of the website.
Also, make sure you have the latest BIOS installed. Update the BIOS if needed.
May 5th, 2008 at 11:53 pm
I have a problem with my Tecra 8200 where the AC adaptor LED (left most LED) is flashing amber. I suspect a problem with the internal PSU but I cannot get access to it. Does anyone know how I could dismantle this machine further to gain access to this?
Thanks very much in advance,
Peter

One was thrown out at work and I grabbed it.
It works somewhat, but I think it was dropped. Sometimes it freezes up during startup then goes to blue screen and says stop: 0×0000007f then the rest 0x… are zeros (which means hardware failure somewhere). Anyways I loaded knoppix (live CD) and ran the memtest right from prompt and it seems to run fine until I push near/around the top left of the keyboard (I think right above the processor) and then the memtest starts continuously listing off errors as it runs the test until I push in that area again, but it’s intermittant and mostly gives errors. Couple of times I did manage to get knoppix fully loaded but as soon as I tapped that left corner the screen blanked and it froze up.
Anyways, how do I take it apart so I can look to see if the processor is seated properly. I can’t seem to crack the cases in half. I’ve removed screws, hd, battery, modem, dvd drive as shown in the toshiba 8100 field service manual but it doesn’t give any direction on how to split the two halves to, say, change a processor. I’m kinda stuck.
Any hints or tips would be greatly appreciated. Maybe the best tip is to just get rid of it but I would hope someone would have some type of skill to help me out.
Again, greatly appreciated if anyone could.
May 20th, 2008 at 4:41 pm
Actually I found this, thanks for the help on your page. http://gopaultech.com/wp-content/images/Tecra%208100%20Disassembly.pdf
July 8th, 2008 at 12:48 pm
This has been very helpful, I also have a tecra 8100 which is exhibiting similar screen problems, only the screen is premanently black, I can however see a faint outline in the right light when I turn it on.
I have tried replacing the inverter board, but this has not worked. Can you advise what else may be the cause of this problem?
Grateful for any tips
September 14th, 2008 at 8:46 pm
Thank you for your help I love this site. I think I need too buy a new inverter. where can i buy it.?

I fixed the memory problem on my Tecra 8100 it was 6 pins in slot B that solder had come loose 3 pins on both of the outside.
Other problem is AC power. I have to put pressure on the cord for AC power to work. I resoldered but no success. I may try again later.
As for your screen going blank, I’m not to sure. Usually it’s the inverter board other times its the lights. I’m trying to fix an LCD monitor thrown out at work and the invertor section of the board is gone. Couple of diodes blown and some failing capacitors and transistors. I know which ones, all I need is to find the time and the parts to do it. Best of luck! I’ll see if I can come up with something.
