SOURCE: Mitsubishi WS-55819 power issue

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

Sounds like bad convergence IC's; this set uses two STK-392-570 IC CHIPS; both should be replaced and the blue 3.9 ohm resistors in front of them should be checked. Get someone who has done this repair on this kind of set before--it is usually not something for a do it yourself person; the middle pc board needs to be removed to safely replace the chips; then the set needs to be adjusted in the regular and HD modes. If this is helpful, give me a vote. if you need more direct information email me: etower.766@netzero.net

WS 55819 Mitsubishi HDTV , the tv turned off itself. The power light on for couple of second then off again. What is wrong with the TV?


This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Akai, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free.

Mitsubishi WS-55819 HDTV won't power on


At the very least you are not getting any of the Standby power to the Microprocessor (5 vdc). I would concern myself with that area once you get the manual. In the mean time check all the fuses.
