Question about Sony Grand WEGA KDF-60WF655 60" Rear Projection HDTV

1 Answer

I have a Sony Wega LCD Projection 60wf655. When I turn it on, the red light turned green and blinks green 6 or 8 or 10 times or indefinitely. No picture but after a minute of being on the screen glows bluish. no channel or menu displayed. And the power light stays on green. It seems to try and turn on at first with a faint black and then dark grey flash but no picture. I tried shorting the thermal fuse and nothing. All the issues I've found are related to red flashing lights, mine doesn't turn red except when turned off. I have the service manual and have checked every capacitor and board they look good. What could be wrong? The bulb is new and seems fine too. A local shop said maybe a conversion chip? Don't know where that would be. Any help?

    I have tried shorting the thermal fuse wires and no change. I can see bright white light coming from the lens area so I know the bulbs working. But no picture and no red blinking errors.

This could be the "thermal fuse" which usualy is next to the light bulb. Part cost around $5.00. Please check your manual for directions depending on light and times blinking.

    I tried that as well as shorting the thermal fuse wires and no change. I R and Red the bulb to check it and it looks fine. The bulb lights and starts when powered on and I never get a red blinking light. After a minute the TV now glows bright white but no picture.

    The other reason could be the bulb light cover is not properly closed. Read your manual for what the color of light and times blinking means. If this does not work for you, call contact then go to ELECTRONICS then TVs then SUPPORT and look around for the area to chat with a tech (its free) complain about the BLUISH on your screen, could be something related to the ENGINE COLLOR, or COLLOR BLOCK, if your model is protected under the Class Action against Sony due deffective ENGINE COLOR you can probably qualify for a replacement with a brand new TV for a minimal price.
