Re: Fix for Benq FP737s 17" (Q7T3)

update:

Today I continued testen the board, to be 100% sure that the FET's were not faulty I swapped the FET's between the inverters, after powering up the inverter that always worked before still did. So the FET's, transformers and all others transistors besides the 5707's were actually fine.

After desolering, checking and resoldering almost every component from the faulty inverter I still had no idea what the problem could be. I decided to give the monitor just one more chance to live before I would bring it...

Hello,

This is my first post on this forum, my name is Léon, and I am an electronics student from Holland.

I got a FP731, which has the same problem as the rest of these LCD's: the 2SC5707 transistors were blown, the LED was constantly flashing (screen kept rebooting). After opening the case, it quickly became clear that someone else already had a try at fixing it, the fuse was shorted (!) and there was some very messy soldering done on some of the transistors.

After replacing all four 2S5707's...
