Polar 92 E Backlight from TFT Screen defect

We have the Problem that the backlight from the TFT screen is defect.
There is an small inverter card beside the screen where we saw that the blue ceramic capacitor, 22pF 3kV, was blown. We changed the capacitor against a new one but we had no success. The light was a short moment in function and than the capacitor was blown again.

The Problem is that we don't want to Change the whole screen concerning this fault which could Maybe fixed.

Any ideas

 

Hi, sir you must test the power supply for the inverter if is o.k, see his schematic diagrams
2) after you must test some Transistors, diode, or brige rectifier if there are in Short circuit
and replace.
2a) if you do not have the experience and knowledge in electronic, Go:
3) Any Tech TV, can do that, that is normal in LCD TV, Monitors, i recommend you that you take your whole
TFT screen and go to the repair shop, since they are skill to handle the level components.

 

I can provide this inverter board and Polar spare parts if you need.
