The A board will need replacement all audio processing is done on the A board. Your model used two different A boards but the people at www.tvcircuitboards.com can assist with determining which board you require if you send them a email from their website.

Picture is gone! :*(

the picture tube (what makes the TV picture work) has blown out. Just call you nearest tv reapair shop and purchase a new one. (these are kind of expensive!)

(Also, if it's fifteen years old, i think it's time to get a new T.V. hint. hint.)

Very faint picture but sound is fine on my 50" Zenith plasma

Sounds like the Z-sustain board went bad. You will need the board replaced so make sure you find an LG authorized servicer.

Sony tv picture keeps flashing

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.
