Question about Sony KP-53HS10 TV
AFTER THE TV IS ON FOR A SHORT PERIOD, THE SCREEN GOES BLANK BUT THE AUDIO CONTUNUES. THE TIMER RED LIGHT STARTS FLASHING. WHEN THE TV IS TURNED OFF AND ON AGAIN THE SCREEN COMES BACK ON, BUT AFTER A SHORT PERIOD THE TV SCREEN GOES BLANK AGAIN, AND THE TIMER LIGHT STARTS FLASHING AGAIN; THE AUDIO IS UNAFFECTED.
TO GET THE TV SCREEN BACK AGAIN, I HAVE TO TURN OFF THE TV AGAIN AND BACK ON AGAIN. THIS CYCLE WILL GO ON.
HOW DO I GET TO KEEP THE SCREEN FROM GOING BLANK AND THE TIMER LIGHT FROM FLASHING WHJEN THIS HAPPENS?
Try unplugging for 36 hours. I had the same problem but with no sound and picture

Unit is dead, No blinks
- Problem in the standby power section. Might check fuse, R607,
Q601, IC601, R612 and VDR601 (should show open).
Continuous blink once a
second, no pausing - No reply from the jungle IC301 (data
bus is busy, shorted to ground, or held high), IK video path is
One blink - not
used for the self-diagnosis
blinks - B+ over current protection (OCP), unit goes to the
standby mode then displays the 2 blink fault. Could be a short in
supply of any of the circuits.
Three blinks - B+
over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Four blinks - No
vertical Deflection (V STOP), Screen goes to a single horizontal
line then the video signal muted. Check IC1509, Q1505
Five 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.
Six blinks - No
Horizontal (H STOP), no raster, goes to the blinking self-diagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.
