Toshiba Tecra Video problem
Hi y'all. I got a Toshiba Tecra 8100 on which the "backlight" (?) keeps going dim. Basically completely black, but if you look close, you can make out the desktop and mouse pointer. Sometimes it happens immediately after getting into Windows, other times it may not do it at all. Also happens in BIOS if I leave it. Seems to happen more often than not when using the AC adapter but it also occurs on battery power.
Toshiba replaced the whole screen and inverter board last week. I thought for sure that would fix it but no luck. I have to send it back again, but I thought someone out here might be able to help and avoid more trouble.
How to get to the FL inverter?
Hello - I hope you are still out there. I have the same intermittent
problem with my 8100 screen getting dark - then i have to press the
sensor pin to make it come on again. I want to try to clean the
FL inverter contacts but I do not know how to open the laptop to do it.
Would you (or anyone here) be so kind as to tell me how to do it.
Thank you.

Never opened up an LCD - think I'll give it a try when I get home. Anything I should watch out for or recognize when I get in there? Do I have to take the whole case apart?

Would you please tell me how to open the laptop so I can
get to the FL converter to clean the contacts? Thank you
very much.

its just a bad connection between the inverter and the lcd. fix is to clean the contacts on the inverter with a anti-oxidant/contact cleaner. My guess is that unless you sent the unit directly to toshiba, the service center that you sent it to just replaced the lcd and re-seated the fl inverter. if you get it back and it still behaves this way, depress the cover sensor switch and release it. if the backlight comes on, then this is definatly the problem. Pull the lcd apart yourself and clean the fl inverter contacts yourself. quicker and probably cheaper when you factor in downtime.
if the service dept is giving you hassels about this, tell them to look up fsb200123. they should know what it is if they are an authorised service provider.
