Benq et-0004-L problems with one side of the inverter

[ehrja]

Problem with inverter section. It powers and displays the image just a couple of seconds then it gets off.

Only the inferior lamp is working.
The image can be seen with an external light.

When is on is doing a noise and smells bad, I notice a hole in the cable of a ccfl lamp and the noise seems to be originated from that hole which is barely touching the metal case an can be sen plasma between the cable and the metal.

I try with other ccfl lamp but it not power.

first thing, it looks like the board is cracked near the invertor transformer.
so you need to check the tracks under that crack.
and obviously you need to insulate that burned wire - preferably cut out the burned section too.

I guess that is the reflection of the flash light and I already isolate the wire with termofilm.

I wanted to add that all leads in the 8pin chip that is nearest in the picture has -35v
