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. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The audio in Hitachi 62 in rear projection tv was intermittent and now it gone completely, I just replaced the Convergence chips because it had the 3D color separation ,i was able to fix that problem , now...


Model number 55VG825 IS NOT 62 INCH SET, IT IS 55 INCH DLP.

WHAT IS ACTUAL MODEL NUMBER OF YOUR TV?


I can give more information if you give me correct model number---if convergence is now working, it has nothing to do with sound unless you created the problem when you repaired it.

The more info you give me the better I can help you.
