hi

sorry for my bad english, but i think it works.

My prob. all the led´s inside of the display don´t work any more. Is it possible
that there is a fuse gone ??

Welcome to the forum. Are you refering to the indicator LED's (.e.g. power on) or are you refering to the CCFL (backlight) in the LCD? Also, which Thinkpad do you have? T41, T42? Is Puke your real name?

Hi

Puke is not my real name, it´s a nickname waht give me some friends. Anyway, wich Thinkpad i have, lol.
T43p t42 t41p X40 X41t X31 240 and a T43.

But the Probs is the T42. It´s work fine but the BT WLan Akku HDD and so on led´s are dead.
Nothing works, the inverter i have changed and the led´s also don´t work.

Well Puke, if the inverter has been replaced, you are looking at a blown fuse on the systemboard, the LCD cable itself, or a systemboard replacement. Personally I'd start with checking systemboard fuses, then reseating (first) then replacing the LCD cable, then systemboard replacement in that order. Good luck.

Grrrrrrrrr all the fuses on the Systemboard ?

[Harryc]

I'm not certain what your question is, but yes all of the fuses are on the systemboard. There are several T4X fuse diagrams floating around the forum, try a forum search for them.

If all the leds are gone, then replace the F8 fuse and in the the future remember to remove all power - including battery - before plugging / unplugging the lcd cable.
