Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts or search the site by type in the brand name of your set, at its search box at the right column.. It will be best to replace the inverter board as card basis.

SOURCE: No picture, sound works. Screen flickering

It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

That problem is caused by the Y Sustainer board.

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.
