2003-2004 Model Year Grand WEGA Televisions:

Models: KF-42WE610, KF-50WE610, KF-60WE610, KDF-70XBR950, KDF-60XBR950, KDF-42WE655, KDF-50WE655, KDF-55WF655, KDF-60WF655, KDF-55XS955, KDF-60XS955, KF-42WE620, and KF-50WE620.

As technology evolves, Sony continually looks to stand behind the reliability of its televisions. It has come to our attention that a very limited number of televisions manufactured between 2003-2005, after a period of time exhibit a stationary scribble / random line pattern on the screen. Click here to see photos of this symptom.

As part of our commitment to quality, Sony is announcing that for any owner of this model television who paid out-of pocket expenses on or before May 26, 2006 for an estimate or repair service to replace the optical block for this specific issue, Sony will reimburse the customer by mail for his/her parts and labor expenses. To receive reimbursement, please follow completely the directions and terms on the claim form for reimbursement; all claims must be postmarked by May 31, 2007.

In addition, for any customer who later experiences this issue on one of the affected models, Sony will cover the cost of the optical block repair at no charge through September 30, 2007. All other terms of the Sony limited warranty continue to apply.

no and yes
the lamp warning is to alert you that a timer has expired that clocks the approximated life of the lamp in "hours of use".
it is never accurate and is dependent on whether or not it was reset the last time a lamp was replaced.
reset the lamp timer in the users "setup" menu.

the lamp has NOTHING to do with color, it only provides light.

check the connections between the TV and cable/satelite box...the red.green.blue component connector...the red one is likely loose.
if this does not correct you color problem, your optical engine has failed.
very expensive repair, not for the DIY type guy.

I have a Sony Grand Wega KF-60WE610 television. It now seems that the picture is darker than it used to be. I can still watch a show, but many people who have seen my television comment on the poor...


I'm sorry that the pictures on the TV screen is black. Based on the information you have provided, it appears that the issue is with the Lamp itself. The lamp of the TV may have to be replaced within two to three years depends upon the amount of usage.
If the screen becomes dark, the color looks unsual or the LAMP indicator on the front of the LCD projection TV flashes, it is time to replace the lamp.
Thanks for understanding. Please let me know if you require further assistance in replacing the lamp of the TV.

My KP53V45 has sound and a very faint picture all in green with a number of horizontal lines. It also shuts down after 10 to 15 seconds. Is this a projection lamp issue?


Sounds more like a color wheel, if the color wheel is not working properly the on board computer will shut her down. And will get weird colors or flickering colors.
Sometimes will also make noise.

Toshiba 42HM66 has a whirring noise that stops when power off


this is a bad color wheel, however you cannot just change the color wheel on this set you have to replace the entire light engine.

Screen getting dark


If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it

Whining Noise and Image Problems


You better to check the color wheel or Lamp ballast.

Normally, the noise comes from color wheel.
