How to replace cicuit breaker mitsubishi ws 48511


It does not have a circuit breaker but if green light comes on for a few seconds and goes off:

Mitsubishi self check: MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

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

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


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 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 IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

Push power button and it stays on for a couple seconds and then shuts back off. No picture comes on. Thank you Jeanette


To determine what your problem is:

UNPLUG TV ANDTHEN PLUG BACK IN---TURNON---GREEN POWER LIGHT COMES ON FOR A MOMENT ANDGOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.

MY TV IS NOT COMEING ON IT IS MITSUBISHI


This is NOT a solution but a suggestion:

So you may know what is wrong, if power light (green) comes on and then goes off:

PRESS AND HOLD"device" and "menu" buttons on front of tv for at least 5 seconds and thenrelease both together.

Will only turn on for about 3 second with no picture and then turns off. Standby light blinks 6 times


For the KV30HS420, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:

1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)


hope this helps John

Standby light flashes green and red, the pattern is 11 flashes, is this serious


Submit the TV to an authorised SONY workshop for a quote and a full assessment of the actual problems. This repair could prove expensive/uneconomical, but it is up to you. The quote (and their second opinion) should help.

Here is a list of the problems that might have occurred indicated by the number of blinks:

* 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.

* 1 blink = not used for the self-diagnosis

* 2 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.

* 3 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.

* 4 blinks = No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

* 5 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.

* 6 blinks = No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

* 7 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.

* 8 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.

* 9 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).

* 10 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.

I assume the TV has no picture/sound as a result.

No Power


Good Day;

Shutdown at Power Causes: Cause #1 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/device 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. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. 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. Good Luck, big IRISH.

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.

or

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


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
