Hi,
Same stuff I guess, but... I have a HP L1740 which is inside a BenQ, though the exact model I am unable to figure out... It has SMD inverter transistors and the inverter generally looks simpler than q7t3 (of which I have another, exactly the same outside, HP L1740 which I fixed thanks to this forum!)
I resoldered the connections to the high-voltage transformers after it started dying and it was fine for some months. Now, however, it keeps on behaving like follows: it starts up properly, display is nice and shiny, but after a few minutes (sometimes hours) it just shuts off. Not only the backlight, but the complete screen - the green power led goes completely off. If I push the power button the screen wakes up again with no trouble.
Any idea what can be wrong? It looks like the mainboard switches off or sth, but thats unlikely, isn't it? Should I just try resoldering the trafos again?
Thanks for any suggestions!
