Run the diagnostics.

With the TV power cord plugged in, press the 'INPUT and 'MENU' buttons at the same time -- use the buttons on the front of the TV, NOT the buttons on the remote; a diagnostic Error Code Operational Check will begin, utilizing the 'POWER ON' LED (the green 'POWER ON' indicator light).

There will be a pattern of two sets of flashes, with a pause in bewteen flashes; this sequence of flashes will be repeated a total of five times.

The Error Code designations are listed below:

Error Code Description
12 No eror has occurred.
21 X-Ray Protect circuit.
22 Short Protect circuit.
23 Horizontal Deflection failure.
24 Vertical Deflection failure.

I hope this information helps.

Shutdowns


How long does it come on? If on then off, possible short somewhere, if turns off during movie, maybe weak power supply.

Mitsubishi Projection TV Model # VS-50502


The power supply section is having trouble.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

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.

Blown fuse


Sounds like a problem in the transformer (a short) possibly visible as surface burn marks on the transformer coils. This can sometimes be fixed, but is not usually worth it for a small transformer, but easily replaced. Also check that there is not a short where the power cord connects to the workings of the tv, maybe a loose connection or some debris. Hope this helps :)
