How many times does it blink?
- 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 defective.
- One blink - not used for the self-diagnosis
- Two blinks
- B+ over current protection (OCP), unit goes to the standby mode then
displays the 2 blink fault. Could be a short in the power 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.
- Seven blinks
- High voltage shutdown. The high voltage has exceeded 33k and the unit
goes immediately into safety shutdown. Check power supply regulation
and horizontal circuits.
- Eight blinks
- Problem with the audio (AUDIO), unit goes to standby and blinks the
self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some
projection models of Sony TV sets, this code means that T8005 (flyback
transformer), or the associative components in the high voltage
circuits are defective on the D board.
- Nine blinks
- Replace D 6116 and D 6301 on the "G" board, do not resolder as this
will fix the problem temporary. Or Panel Module Error or Thermal Error.
If it is intermittent 9 blinks, meaning sometimes the TV comes on and
other times you get flashing, then change the switching regulator on
the "G" board or check connections. Make sure the regulator is -12 or
-13 (negitive).
Ten blinks -
Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on
the " D" board. If the transistors are bad, check R8051 and IC8005,
also on the "D" board.
The sony HDTV LCD Television goes off every 30 seconds, turns back on after 30 sec, goes on and continues on a loop. the green light stays on all the time.
my sony kdf-e60a20 60in turns on for a min then goes out green light keeps flashing for a min then the sound on comes and the pic come back on then it starts all over again
Tv picture goes out for 30 seconds than comes back on. Stays on for about 90 seconds or so. Then repeats the pattern. The green light stay on steady. I have pulled the lamp. cleaned the screens, dosen't help. Whats wrong? What do I do?
P.S. I use a sound system, I dont know if the tv sound goes out as well.
I bought this TV in 2006 and it keeps going on and off. The green power light stays on all the time, it never blinks.
my 50 inch sony KDF-50E2000 does the on and off loop thing. The tv works fine for about 30 seconds then it like restarts itself, sound and picture shuts off green light blinks for 30 seconds and picture and sound come on for about 30 seconds then starts over again
shut off randomly, now proceeds to blink and i cant turn it back on
sanyo dp42740 shuts its self on and off with froze piture
tv turns off and on
