TX-L42E6YW No image, sound works

Hi everyone,

need some help narrowing down the problem with the

Panasonic TX-L42E6YW TV.

Previously the backlight was replaced on this unit,TV worked fine for some time.

Now there is no image on the TV, audio still works. Backlight works fine too. TV turns on normally, and continues to work, except there's no image displayed.

I checked the Power board test points voltages, and they are according to the normal values from the sevice manual I found online.

There was also mention of test points on the main A board, but I failed to find those labels on the PCB.

Visually all boards look fine.

What are the next things to check? Any advice is helpful.

If you need any photos let me know and I can provide them.

Thanks,

Daniel
