Hiii...

I'm not sure about the chassis number of your tv set..
but I can give a solution for your proble....
It might be the problem at A,B,M board there's no +5V or over voltage +5V...check the IC504 at A board looks like a ic regulator 5V..check c530(470uF/25V),check c540(1000uF/16V)..

HI,

  • 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.
Goodluck,

Why my Sony Wega tv standby light blinks 10 times?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

My sony wega kv-32fq86b, some times it will switch on and stay on, other times it will switch to standby and keep tha standby light flashing.


Hello
Standby light blinking is a fault indication in Sony sets. You just count the exact number of blinks at one time, after switching on and off the set by its front panel power control switch, NOT BY THE REMOTE CONTROL HANSET. Just inform me the exact number of blinks occur there, after counting it at least four times. It will help me to reach the faulty stage, of sometimes to the exact fault location also. OK.

Above and below are service manuals, and above is your user manual. http://elektrotanya.com/sony_ag3e_chassis_kvdr29m80b.pdf/download.html
"the standby light sometimes flashes 5 times every 3 seconds" (sic) With regard to those flashes, if there is no mention of it in any of the manuals, from the links i have provided, then i would just keep an eye on it. But you have no real problem.

TV won't turn on


The 9 blinks usually mean that the power regulators are shot. This is a relatively simple repair and is a wear and tear item. Expect about $25-$35 in parts plus the local labor rate for the total repair cost. If you want to try and repair it your self, I can look up the part designations and numbers.
Keep me posted.

Sounds like a power supply problem. How many times does the light blink? The times that the light blinks could possibly tell you around what circuit is having a problem.

Due to playstation or dvd nothing will happen. 5 red flashes means jungle ic failure shows this display. Technical person only sorted out the above problem.
