Sony Wega KDF-55WF655 blue ghost problem after replacing lamp

Bought TV in DEC 04. In Jan 07 the TV would start, shut down, then restart repeatedly. Tech guy replaced the lamp. This fixed the start-up problem but created a blue ghost over the center section of the screen. I kept the old lamp and put it back in. The old lamp worked and the blue ghost went away. I said the problem was due to new lamp. The tech guy and Sony said that's not possible. He put a second new lamp in and it had the same blue ghost problem. Then I put the old lamp back in and the blue ghost went away. The tech guy said there is slight evidence of blue ghost at the bottom edge of the screen. My point is that's not objectionable. The tech guy says the light box has to be replaced. I say there is something wrong with the new lamps supplied by Sony. The tech guy says the new lamp is stronger and it magnifies a problem with the light box that allows the blue light to "leak thru" and show in areas where they should be no blue light. Does this make sense? I beleive Sony redesigned the lamp; it's a different part number. It's a stronger lamp that puts more stress on the light box and creates new repair problems for the TV. Anyone have any info to share? I plan to stay with the old lamp as long as I can. I can't figure out why the lamp didn't work properly before and is working fine now.

It is a defective light engine and it must be replaced. I hope you have a warranty because Sony will not help you.

Problem for Sony Grand WEGA KDF-55WF655. Hello,


5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
Thanks.
