Question about Sony Grand WEGA KDF-55XS955 55" Rear Projection HDTV

BLUE SCREEN ON KDF-55XS955

THE SET WOULD TURN OFF AND ON WITH NO REASON. I HAD A PROBLEM IN THE PAST WITH THE THERMAL FUSE SO I REPLACED IT. THAT DIDN'T FIX IT. I FOUND OUT IT WAS THE LAMP SO I REPLACED THAT AND FIXED IT.\
HOWEVER THE PICTURE WAS ON AN ANGLE. I THOUGHT IT PROBABLY WAS THAT THE OPTICL BLOCK WAS IN COOKED. I FIXED IT BUT THEN WHEN i TURNED THE TV ON THE SCREEN IS BLUE. I CAN SEE THE PICTURE BEHIND IT .

Check the LVDS cable. That is the multi conductor (actually individual little tiny shielded twisted pairs) cable that feeds the video signals to the light engine. It is very easy (don't ask me how I know) to damage the thing when moving the modules around. The cable is a real piece of work and impossible to repair.
The manufacturers have seemingly no consideration for the people that have to work on these things. (let alone the poor owners that shell out big bucks thinking they will last a long time)
Hope Ya Fix It!

    ya, little tiny blue unrepairable things. Check to see if any of the wires are pulled out of the connectors.

  • Greg Collins Jan 12, 2008

    Check all the other connectors. It wasn't doing this to start
    with right? Something you worked on is amiss. I replaced a
    P/S board on one of these once, and didn't get it seated all the way
    into the motherboard connector. They had little lock tabs that
    get in the way of the mating connector shell and doesn't go down all
    the way. Sony does a good job of connectorizing these sets but it
    is still possible to not get them right.

I have a KDF-55XS955 or KDF-60SX955 it has lots of dark blue dots. I understand this is under warranty by sony due to the large problem and complain.


You are correct. It was under extended warranty from Sony.

Unfortunately, that program ended on December 31, 2008. Your set is no longer covered by Sony for this problem. It is, however, still fixable.

Expect to pay about $500-800.00 for the Light Engine and around $200+ in labor to install it. Once in, though, the light engine will take care of those blue dots.
