Hello,
I have a monitor and I´ve found the problem is the back light. It uses inverter FIF1742-60A and I´ve seen for 1 or 2 seconds I have high voltage output. Now I´m wondering if the board itself have some problem due a feedback or similar or may be some of the lamp is not working and this is the reason why the inverter stops.
If I measure at lamp connectors I don´t get any resistance between terminals... on 4 connectors...
The brain of the board is MP1048.
How to test them? I have seen useful CCFL testers in Internet.
