What does a 2-3 dignostic code on a Mitsubishi 55819 mean?

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

It is a little misleading but means something in Horizontal or high voltage circuit (covers a lot of area inside the set) is bad.

Going to need a service manual, etc to try to track it down.

Entire chassis for this set can be removed====called a light box.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

Mitsubishi WS-55819 turns off after about one second upon power up. Help

try the self test: when it goes off press and hold the menu and input buttons at same time for about seven seconds and release both.

power light blinks two digit code like, one blink, two blink, a pause and repeats it several times, this code will indicate area of problem.

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.
Above, a service and repair manual, above that are two user manuals.

Mitsubishi WS-55819 Won't turn on

If F9A04 and F9A05 are open the convergence ICs will need to be replaced as well as the two pico fuses. You will need two STK392-570 Convergence ICs and two 5 amp pico fuses. You ca get the replacement parts at the following link with free installation instructions. heres thelink.

Code 22 indicates that your set is in shut down due to what is called Short Protect. The most likely cause is the Converge Ic's drawing too much current and opening one or 2 fuses. Normal repair cost varies by area and servicer. Expect 250 to 350 plus the service call. I normally do this on site.

Can the WS-55819 be reset through a reset button?

Code 22 is short protect. Recheck your work. Did you check and replace open fuses and/or Convergence IC's. The Conv. IC's normally open at least one fuse when they go out.

LED Blinking

Okay 2 blinks isnt a error code, so your set isnt shutting down due to a protection issue, so I would suspect one of the low voltage regulator transistors or the horizontal output transistor as being defective

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
