Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

2 Answers

Intermittant lamp cycling

I just replaced the 1468798-14 Lamp Driver with a 1468798-16. The TV comes on, and I get a picture for about 30 seconds and then the picture/lamp goes out while the green light blinks. Then the picture/lamp comes back for about 30 seconds. This goes on indefinitely. The lamp driver error warning happens intermittently as well. Bad lamp or something worse?

Picture and sound go off every 5 minutes then comes back on
I had this problem (every 30 seconds, not 5 minutes) and ordered a new replacement XL2200 lamp from Sony and that fixed it. By the way, the lamp installs from the front so there's no need to pull your TV out from the wall. Look at you manual, it is accurate in this respect. My lamp only lasted about 15 months. It costs $200 plus about $16 to ship. You can order direct from Sony on line service.

Same problem: picture goes out
Sounds like you need to replace the lamp. The owners manual should show you how to replace the lamp. You can order the lamp through Sony on their website. Good Luck

No Picture/Sound
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
the part number for the lamp is XL2000U. Its available for $200 at http://servicesales.sel.sony.com/ecom/accessories/web/productSearch.do. Use the Part or Accessory Number to locate the part.
