The Problem you are having is a Cathode to Grid Short in the Red CRT,When it Shorts the screen will Go all Bright Red and shut Down,The Best fix Would Be to Replace the Defective CRT (GUN)

My Sony Projection TV Model # KP-51HW40 currently has a GREEN screen, no picture, and only sound coming from the TV. HELP what is the part that needs to be replaced


Sounds like the Green CRT drive board is needing replacement. The Green CRT could also be bad but usually the set will shut down if its the CRT, so I would try the Green CRT drive you can get one from www.tvrepairworld.com

Screen shakes / jumps vertically on my Sony KP-51HW40


The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
