If the adjustment of the screen settings does not fix your problem, its likely that one or more of the CRTs (picture tubes) is defective.

And, the CRTs for these sets are hard to find and expensive.

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.

MY problem with Sony KP-53S35 53 in. Rear Projection Television. When the TV powers on, the red light blinks until the picture comes on, then the red light blinks go off. I had to wait more than 5 minutes...


the number of flashes of the red indicator lamp points to the possible cause of the delay of the raster or picture, but usually it's an indicator of an emission unbalance between crt(picture tube) guns. the picture will take longer to show up as the emission on either of the picture tubes goes down.

Grey Screen with 480p signals (or higher)


I've had a KP 53HS10 for close to 8 years I think. 4 years ago the picture started blinking after long use, then more and more often. I had a repairman come and replace the tuner card (that's all I know about what he did). Now that I finally have HD from cable, I've found that 720 doesn't work and 1080i works, but the picture blinks on and off apparently struggling with some inner problems. Everything looks great, for a second and then it blinks. The red light blinks 5 times repeatedly while this is going on. I called SONY 5 times means get a repair man. I searching forms like this for help as well.
