DEAD SET I have a dead set. The power light blinks 2 times followed by 3 blinks. I could use some help trouble shooting that error code. NO SHORTS are found on pwr or HV boards. THANKS

ost models have a self-diagnosis feature to help determine shutdown problems.

To enable this feature do the following....

1) Turn the tv on and then let it shutdown
2) Press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds
3) After 5 seconds the power LED on the front panel will blink a two digit sequence.

This will commonly be one set of blinks followed by a short pause then another set of blinks.
This will repeat around five times.

1 - 2 = no error detected

2 - 1 = X-ray protect (high voltage or beam current)

2 - 2 = Short protect (short detected - commonly caused by convergence failure - to repair this check out site for a convergence kit)

2 - 3 = Deflection protect

2 - 4 = Vertical protect


Note: A constant blink on certain models will typically be caused by a fault in the DM model. To repair this check out site a "blinking green light kit"

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device”(ALSO called input) and “menu” buttons on front of tv for at least 5 seconds and then release both together.

The set should blink a two digit error code, like---2 blinks, a pause and 2 blinks---it will repeat it about 5 times.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC'S and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


If you let me know what error code you find I will tell you what may or may not be done--I hope you find 2,2.

If this information helped you rate this solution as I do this here for free.

Good Day,

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times.
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source)
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC).

2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.

3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.

I hope this was helpful, BIG IRISH.

The model you have selected should have a self check feature: when turns off and the green power light goes off:

ON THE FRONT OF THE SET PRESS AND HOLD BOTH MENU AND INPUT(some sets the input is called device) together for at least 5 seconds and then release both buttons.

The power light should blink a two digit error code: for example: 2 blinks, a pause and 2 blinks--it will repeat the code about 10 times.

error codes for this set:

1, then 2 no error detected
2, then 1 X-ray protection
2, then 2 short protection
2, then 3 deflection circuit problem
2, then 4 vertical deflection problem


2, then 2 is the most common and easiest to fix.

Let me know what you find and if 2,2 I have detailed instructions for repairing that kind of trouble.

SYMPTOMS
Dead or Shutdown symptoms.
RESOLUTION
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.

5. Dead. 5 blinks then 3 blinks. Found shorted Damper diode D504. Q502 has a built in damper, as well.

6. The TV does not turn On and the LED flashers 9 times.
Found one side of R610 open on the Base of Q690 on the A board.

7. Dead, 9 flashes, Q606
Would not start when cold, has stand by 5 but relay never energize.
No response from front panel or remote controls.
9 blinks is not in service manual.

Found Q606 (Zero Det.), on the A Board, had no soldered on the collector
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
to fail on the A Board.

10. No picture or sound. Standby flashes.
Found Q512 (Pin Out) shorted. on the A Board.





11. Dead. No sound or picture.
Found the FBT and Q502 were shorted, and R615 open on the A Board.

12. Dead
No power, Stand by light flashes 4 times.
Found T604 and IC601, replaced.
Found D611 on the A Board was the cause of the symptom.

13. Dead.
Found D534 shorted on the A Board.

14. Shutdown 4 Blinks.
Replacing R595, OCP Latch Q532 on the A Board, fixed the set.
PN 1-247-891-00, 330K 1/4 watt.

15. Unit shuts down after 15 mins.
Immediate shutdown - sometimes it give a 3 blink, sometimes nothing.
Found R595 (330K) was open located in the Q532 OCP Latch circuit.
R595 P/N 124789100 330k 1/4w

16. Won't power up. LED Blinks 4 times, B+ is very low
B+ is at 49V, +15/-15 only coming up to about 1 volt.
Wth Hor Out disconnected B+ only comes up to 50v.
Found D611 on the A Board was the cause of the symptom.

17. Intermittently does not turn on
Found a intermittent C633 on pin # 3 of IC600.
C663 P/N 113647911 Film cap .001uf 100v
