Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV
I have been having a problem with my tv it will be on and all of a sudden you have no picture the green light flashes on the standby and will come back on in a couple miniutes. Then it dsoes it again and again. It seems to be getting worse. I tryed watching a DVD and it does the same thing. Could it be the bulb going bad? the bulb light is not on or turning red. please help it is out of waranty.
Randy it's the lamp! The Wega uses Xl-2200 lamp in a full housing assembly, Sony p/n#A-1085-447-A They're not cheap. When the lamp nears it's end of life period the picture can look a bit dim, cycle on/off and eventually fail completely. To get at the lamp merely remove the two thumb tight screws behind left and right sides of the lower panel. Panel snaps off then.. Next remove the lamp housing cover, another thumb tight screw. The new lamp will come with an allen wrench to remove and re-install the new light housing ... :) If you have any questions let me know. Bill

This problem is most likely the bulb, the bulb socket or the bulb power supply circuit. You will need to try the easy things first, like try resetting the bulb in the socket, then you will need to replace the bulb, then if you have no TV repair experience, you will need to have the set serviced by an authorized repair shop.Good Luck

The best way to replace the lamp in this unit would be to go to page 16 of the owners manual. it will explain in detail how to do this. If you do not have the owners manual, I found you a free download of this owners manual. Go here:

Good Luck with this.
Like I said, if you replace the bulb,and that did not fix the problem, you have a lamp power supply problem.
I told you that the lamp power supply was bad if you tied the bulb. Tyhe lamp power supply is the Ballast circuit.

My friend have a tech check your tv dont waste anytime your tv is having problems in the power circuit or in the Horizontal circuit or probably there is some cold solder in the power supply circuit.this should be checked out for repairs.good luck.

I took out the bulb and it is in good shape.
I guess I need to take it to a service guy. There is no one in my area and the one guy called and said he could look at it july 19th and that is to long.
I don't understand there is no red light flashing and the bulb light is not on.
I ordered a service manual but it has not come in yet. I found a local guy who told me to bring it in and he will look at it. It is to big for him to pick up. Thanks for your suggestions but I think it must be electrical and need a tech to look at it
I have taken the Tv to a profesional and it was a BALACE.
BALACE
I think your pro's should have known this.
