LG37LF65 PROBLEM

[markopolo]

Hello!

I have a problem with LG37LF65 first the picture has been deemed and after a while gone.
I have realised that the C203 on the power board has been boiled.
I have changed it and all the capacitors on the secondary power suply.
I have tested the 24 V and 12V with a dummy load and everything is stable.
But I still do not have a picture anly the voice.
The inverter has 24V and on the inverter on pin is 4.5V so the bulb should glow but it doesn't.
While making a discovery I found out that the 19V when the load is connected falls on 18.1V.
If this is ok then the only thing that has left is the inverter board.
Am I right ?
I'd appreciate it if you could assist me with any ideas or send me a complete schematic diagram.

Thank you in advance!

Or the lamp(s), or the bulb connectors, or ...

If you have no picture but sound, 24 volts going to the panel and the 5 volt inverter on, bad panel not cost effective. I do show inverters are available google the full product CODE like LG 37LF65-ZC.AECYLJG then "inverter."
