SOURCE: TV shuts down

Remove the lamp assembly, There will be a screen on the top and bottom of the assy remove all dust from these screens. also check the tube at the top of of the lamp receptical this is an air cooling pathway. reassemble and fire it up. This worked for me and saved some serious coin judging from some of the other solutions I have seen (lamp and balast) ouch!!!

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

The picture goes off, the power/standby light


Sony KDF-60XS955 picture goes and power/standby light light flashes


Hi,

Most likely you have bulb failure. First step in troubleshooting is "Change the Lamp or Bulb". Lightning, power line bumps and collisions with vacuum cleaners can all shorten lamp life. Rough handling in shipment can also happen without your knowledge.

+90% of all Sony LCD Rear Projector "No Picture or Intermittent Picture" faults are related to bulb failure.

If new lamp does not improve the situation, then hands-on troubleshooting by someone that has parts and knows how the unit works is the only practical remedy.
