It sounds like your light engine is defective. My Projection LCD had this happen and it started with a growing blue haze, others experienced a yellow haze, I suspect yours is manifesting with a green green haze.
It is a very expensive fix, depending on the age of your set, you may find it cheaper to replace it with something new, because a light engine itself costs nearly $2000 and another few hundred to install and align, not something a do-it-yourselfer is able to do

Could be a bad lamp again. If this TV uses the XL2200 lamp, they are known for this intermittent behavior. If its not the lamp, a tech can access the self-diagnosis screen to see what's causing this failure.

AKAI Rear Projection 46"TV has a blank picture with sound only


Hello,


Is it a CRT or a DLP/LCD projector? If not a CRT, a worn-out projection lamp can cause this symptom. When it is a DLP projector, a faulty Colour Wheel sensor can be the additional problem. If it is a CRT projection unit the High Voltage and deflection circuit must be examined...

Please tell me more about your unit...

We keep losing sound and picture on our TV


If you haven't replaced the lamp, it is almost certainly time to change it. A weak lamp will cause the TV to play for a short time. As the old weak lamp heats up, it draws more current, and the reflector in the lamp, having become cloudy over time, converts the light into more heat rather than reflected it out into the set. Eventually the lamp draws too much current and the set turns it off, going into a restart cycle. Buy an original Sony lamp, as the aftermarket replacement lamps are known trouble makers. Be sure to rate this solution. Thanks!

No picture


If the red light stays steady, and the green light blinks 9 times then repeats, it is most likely the lamp #23311083A about $200. Otherwise, if a cooling fan is not working, it could possibly cause a shutdown problem. You can't always tell a bulb is bad by looking at it. Another possibility is the lamp ballast, but I would try a new bulb first.
