Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV

1 Answer

Sony 55 inch. I am getting sound but no picture out of each input. The lamp was replaced less then 2 years ago an the fan seems to be working properly. There is a green light blinking from the "service only" port in the back.

    i don't know if his makes a difference, but the display that says what input is being used (video 1,2,3, etc.) still works, just no picture from any source.

That blinking green light signals the fact that the power source has detected a short and is in protected mode. To find out what happened (if it's bulb, LCD or image processor related) the tv must be opened and the voltages tested - the one that is lower than it should be (or missing completely) is the one powering the failed part.
If the problem ends up to be the image processor you will have to replace the entire board. Since new boards aren't available anywhere else you will have to call an authorised repairman.

    In that case there is something similar happening there - the power source has detected a short but it's a small one that doesn't affect the rest of the tv. Since the menu appears on the screen then the defect is in the AV switch circuits. The fix isn't very complicated - all you will have to do is to replace the switching circuits - but again, it must be done by a pro, the solderings are very delicate.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.You can find it here: http://www.discount-merchant.com/Sony-XL-2200-TV-Bare-Lamp-Bulb-p/sony_xl-2200u_a1601753a_lamp.htm?Click=48173 Have a blessed one!

Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.

Sony Grand Wega 55" LCD ml # KDF-55WF655 goes protective shutdown


This is the lamp going bad. For some reason, it doesn't spit out that lamp error, it just keeps refiring the lamp and it just cycles forever. When the lamp totally fails, you will get the lamp led lit. Replace the lamp to resolve.
