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.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

SOUND AND PIC GOES OUT FOR 30 SECONDS, THEN PIC COMES BACK THEN SOUND. IS THIS THE LAMP OR THERMAL FUSE OR WHAT.


The lamp is going bad. If it was the thermal fuse it would not be intermittent. It is very common for some Sony sets like yours to do exactly what you describe when the lamp is going bad.

Sony WEGA 50 turning off every 30 seconds


The protection circuit is cutting in and out and it is really just a high current detection system.
This is very typical of loose connections and cold solder joints which are easily diagnosed by giving the set a whack with your hand in a few strategic places.
Also check the fuse on the power supply board .
