No Picture/Sound I have a sony grand wega KF-60XBR800 after I turn it on the sound and picture goes out for approx 15-30 seconds then comes back on, the picture looks good sound is good then 1-2 minutes later it goes out again.the stand-by red light is flashing every second the picture is out. Is it the bulb ? does it need replacing again I just replaced it less then two years ago. My friend got the same TV at the same time and has never replaced the bulb ?

Can you go to the error menu?
im assuming it's the lamp however the error menu will tell me more
If the standby light blinks five times repeatedly, that's indication of a "Lamp driver error". The probable cause listed is, "lamp driver faulty". Its also possible that the internal antenna used to detect the presence of high voltage has become mis-positioned. The lamp driver provides the high voltage. If no high voltage is detected, it is assumed that the lamp driver is faulty.
Otherwise, it is assumed that the lamp is bad and the LAMP LED lights
