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.

Why wont my mitsubishi big screen tv turn on? the green light comes on but then shuts right back off.


Model number given indicates it should be a 2000 year model.

If so, it should have the self check feature; try to turn the set on and when the green light goes off: On the front of the set press and hold both the menu and input buttons for at least five seconds and then release both buttons.

Power light will blink a two digit error code like: 2 blinks,pause and 2 blinks (2,2 error code is most common one). It will repeat the error code several times.

Let me know what error code you find and I will tell you what it may mean.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

Mitsubishi WS-55807 Won't Turn On


The TV is on protect mode. The clicking sound is the protection switchthat keep turning the TV off to prevent further damage, this happenswhen a fault had been detected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Alsoensure that the fault is not coming from a faulty receiver box sendingbad signal, check if you get same problem with no receiver boxor dvd connected.

If that does not work, and you keep having a flashingled on front of the TV, and tv turning off by itself after a while,that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.

2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faultsthat can occur are a blown capacitor on power board, aconvergence IC has blown, or a fault on Digital board.

Check alsothe video cable or any external connection cable, if the cable is shorting, or the connector is bad, youcan get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

RCA will not turn on


I had this problem on My RCA tv, what I found was a couple of bad green capacitors in power suply there are around three of them I just replaced 2 of them if I am not mistaken one of them is C120 but if not change all three this are the value of the ones I replaced 2200uf 16v and 220uf 35v, if you see on top of the green capacitors you will notice they are bad.

My tv is working for more than a months and I had the same problem as you are having.
