Good Day; 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 OPEN FUSES F9A04 PART # 283P044020 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. IC8C01 and 02> 267P141030 HIC; STK392-110. These parts are the most common part to fail in this model.

they are fairly similar to each other, did you get a error code from the led by pressing menu and input both in together and holding for 5 seconds?

Hi name is Ernie, and i have a mitsubishi vs-50501a .... my problem is that the picture is out.. i got sound but no picture.. the problem started with the tv turning off after 15min. then i would turn it back on, 15min later it turned off again. So now it stays on but no picture.. let me know if i can fix it myself.. im mechanically incline.. thanks.

It definitely sounds like it's time to have a TV repair man come check it out, or you will have to bring your TV into a TV repair shop. If you are familiar with working on TV's and have the proper equipment and electrical knowledge, you may be able to take apart the TV yourself and check for damaged capacitors, or boards that need to be replaced. I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

there is probably quite a few "dry joints" that needs re soldering in the power supply section.
This should solve your problems rather than buying a new one.
Good luck and Thanks for using fixya.

Hello.
in VS models there is no such a thing as a lamp. Your TV have 3 CRT tubes (picture tubes) each of them dedicated to Green, Red and Blue part of image accordingly.
It is not the part that you can easy replace by yourself and it cost new around $600 and just to refurbish existing one around $320.
But you have to refurbish all three of them at the same time. So we are talking about $1000 just for parts, not to mention enormous effort to align everything back together.
If you have bad CRT in your TV - I would advise just to trash it and invest in new one.
Lamp is replaceable in DLP projection Mitsubishi TV and it is next generation of TV"s. Model number starts with: "WD".
If you still insist on part number - I need to know what color of CRT you need - they have different part numbers.
Best regards
Russ.

I would be looking for broken solder points on the underside of the signal board. Touch up with an iron and fresh solder. Trace the speaker wires to the plug on the board for a good starting point. If no obvious cracks look in immediate vicinity. Goodluck.

Google to Encompass Parts Distribution and type in model number 1-800-638-3328

no picture but have sound

Yes,ur tv have crts coolants problems,it dead.Need it crts coolants replacement.Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a crt coolants replacement kit and follow the tutor dvd instructions to rejuvenate ur crts by replacing the crts coolants.

I had this happen on my WS55909 about 2 years ago. I dont remember what the circuit id's for the fuses were, but out of 6 fuses on the middle board, the two in the middle were blown. I traced the circuit schematic and found that only the convergence IC could cause these fuses to blow. It sounds like you already put in a new convergence IC (the one with the big-*** heat-sink which probably also needs a fan) but you need to make sure all those fuses on that board are still good. After I replaced that IC, my TV still didn't work. I went and double checked for continuity of all the fuses on that board and one was blown (after checking all of them and replacing the IC). Replaced it and the TV has worked ever since. Total repair cost was 23 bucks. Professionals recommended that I would be better off just buying a LCD TV than fixing my rear projection TV, but I still dont think you can get one of those as big as 55" for only 23 bucks! ****. BTW, mitsubishi would probably tell you otherwise, but you don't have to use those "littlefuse" fuses. I soldered in a fuse-holder for a glass fuse of the same value (5amp 125v in my case) that can be purchased at radio shack. A fuse is a fuse. My TV never burst into flames.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

• Screen Looks 3-D
