My Mitsubishi WS-55819 picture turns a bluish cloudy after a while. It clears up by itself and then does it again. I noticed that when this happens it takes longer to show a picture when turned off then back on

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

Well I have a Mitsubishi WS-65413 65 in. Rear Projection Television and when I power it on in the morning it looks as if the picture on the bottom of the screen is bending and parts of the picture "double up" but like the person above me said after it gets warmed up it goes back to normal but every 3 or 4 hours it might get messed up for a min...Anyways: Is it the picture tube going out?? If so how does anyone know how much it would cost to repair/replace & What is a "Convergence Module"?? I don't know if my T.V has one of those or not but if it doesnt is that the problem perhaps?? Please help me or ill be forced to go outside... :-( ..... thanx 4 the help ppl!! -

SOURCE: 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.

SOURCE: WS-55511 55in volume turns up by itself & can't switch devices

The remote is not the problem. The switch for volume up on the control panel has become leaky. Very common problem for this generation Mitsubishi. If you don't mind not having the control panel working you can disconnect it and the set will work just fine with the remote. To disconnect the control panel pull the speaker grill, it just snaps off, and remove the front access panel. Once that is done you'll see a cable going to the switches just disconnect it.

No, that'll do it. Once you've changed em you'll know right away if somethin isn't right. But take faith and fire that puppy up. If the pix is good you did good. If something is amiss. I'd be happy to walk you through it. My money is on you though.
