Sony Trinitron WEGA KV-XJ29M50 29" TV - Dead, LED flashes 2 times

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

No Picture

4 flashed on that model mean a vertical deflection trouble.
Look for solder on it. IC 541 TDA 8172.

Unfortunately, the Power Supply has spat the dummy out. It is giving enough power to light the LED but not enough to run the set. To replace it will probably cost more than buying a new set. But ask around your local repairers for a price before you make any decisions...

4 flashes usually indicates trouble in the vertical circuits. Replace the Vertical output IC and the bypass 220mf Cap. to insure reliability. I don`t know about not hearing the relay click, you may have just blown the power fuse or also may have to troubleshoot the the power supply. ------ Eagle2

JVC AV-32260 timer led flashes

When your set first turns on it runs a systems check to see if the boards inside are safe to apply voltage to. also it checks the power supply to see if it is safe to power up.
Either it needs a factory reset which the procedure changes for each model. or it simply has more wrong with it after the surge and requires more to fix it then the cost of a new set.
The best bet is to look on EBAY for a similar set with something like a broken screen. swap out your screen into its chassis. 
if you do not feel up to the challenge of doing that you may be looking at repair costs and parts that are more then a new set.

Kv24fs120 dead set with two led blinks

Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.


2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).

Blinks twice pause blinks 4 times

Dead or Shutdown symptoms.
Dead symptom reported to be caused by the following:
1. Dead.
Found Q601 & Q602 shorted, R615 open, and IC600 on the A Board were the cause of the symptom.

2. Dead.
Found D614, Zener diode, on B+ line was shorted.

3. Set shutdown and the standby LED blinks 3 then 5 times.
Found 200v line was low. Disconnected CN706 on the C Board and found 200v now
present on CN706/pin 7.
Found: IC702 (C board) shorted the 200 volt line.
HQ Comments: C541 on the A Board could become defective if the 200v line is shorted since
the polarity on the capacitor will become reversed. R553 fuse resistor could also be opened
on the A Board.

4. Error code of 4 blinks .
Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.

No response from front panel or remote controls.
9 blinks is not in service manual.

of the transistor causing an intermittent connection.
Soldered the collector of Q606 and set returned to operation.
HQ Comments: Also refer to E30968554.

8. Dead. 5 blinks or 3 blinks
Found on the A Board D611 in the Power Supply open, and Hor. Output Q502 shorted.

9. Found Power Supply components D611 shorted causing Q600, Q601, and R615
