Here are the Sony blink codes. I would download the service manual for your set from one of the sites that advertise here to verify this. If a vertical circuit failure is correct, that is a very affordable fix at any repair shop.
  • 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.

Sony trinitron 32 inch television model no. KV-32FS13 doesnt have any video nor audio and standby light just blinks about 4 times


Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check for any loose sodering points at the vertical output section.

Usually Sony and LG Blinking Codes are the same. Here is what I have.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  • 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

Tv will not come on. stand by light blinks no


Sony Blinking Codes
Many of the later model Sony TV's have a built in Self- Diagnosis function. If
the timer/standby indicator is blinking, this could be an indication of the
problem with the unit. The diagnostic blinking will occur automatically with no
action required by you to engage it.
The timing of the blinking you see would be as follows: two to eight blinks
(depending on the fault) about a third of a second apart, then pauses for 3
seconds, then the two to eight blinks about a third of a second apart again.
Here is a list of the problems that might have occurred indicated by the
number of blinks. The words in parentheses are those which you will see for
each of these faults on a diagnosis screen described later in this article.
Unit is dead and there are 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 As Discussed Above---
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 Vert. Deflection (V STOP), Screen goes to a single
horizontal line then the video signal muted. Check IC1509, Q1505
FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,
try turning up screen slightly.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.
Intermittent problems ?? This is a great feature. You can also bring up
these fault codes ON-SCREEN to see a list of the problem numbers with the
abbreviation of the problem and the number of times this problem has
occurred. This is slightly different than entering the service mode. To see the
diagnostic screen, Press the following buttons:
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
codes.
So, now that you know about these self-diagnostics, how do you use them?
Say that you have a set with a black screen. You see that the LED is blinking
4 times....This would tell you that you have no vertical and that is why the
video is muted. If it was blinking 6 times, you would know that you have a
horizontal fault.
It's not a sure cure, but it's a little better than a poke in the eye with a sharp
stick.
IMPORTANT: after you repair the unit, PLEASE clear the values on this
diagnostic screen. These codes do not reset themselves after the fault is
corrected, so if you don't clear them, you'll be seeing "old" fault codes the
next time you enter this screen.
Clearing is done by going into the service mode ( display, channel, 5,
volume plus, then power ) then press 8 and Enter, which of course returns
everything to the factory preset condition.

Sony tv wont turn on, standby light just flashes


I had the same problem guys! This is what I did:

My T.V. wouldn't turn on. The standby light was flashing six times, then four, then seven...I called Sony and they told me to unplug it for a couple of minutes, then try it again...didn't work....BUT, I have found a solution:

Try unpluging your T.V. for 4 hours+, then turn it back on. Worked for me! It's called a "hard reset" by sony. I had my T.V. unplugged for the whole day though.
