I have a 2007 Sony 50" Grand WEGAï¿½ï¿½¢ Rear Projection TV, Model # KF-50WE610 . I replaced the lamp about 2 months ago. That was the first time the lamp had ever been replaced. Now I am having a new problem. The TV keeps losing it's video and audio feed. The green light remains (meaning it doesn't shut off), and then after a minute or so, the audio and video feed comes back on. If, while the audio/video disappears, I shut off the TV, the red light blinks 5 times. I have unplugged it for more than 60 seconds and plugged it straight to the wall and not back into the power strip, but the problem remains. Does anyone know what is causing this issue and what the fix is?
