This model is famous for capacitors being bad in the low voltage regulators on the signal board. Also has been known for cold solder connections in the power supply to the convergence IC. I don't have my notes at home but I belive that model only uses one IC for convergence, STK393-570. You cant see it from the back because of it being hidden by its heat sink.

Mitsubishi VS50605 rear projection TV won't come on


The power supply caps in the light engine power supply were faulty when they were installed. You need to remove the power supply and take it to your local electronics shop where they can remove the (7) faulty 1000uf 16v electrolytic capacitors and insert new ones. If you remove the power supply yourself (takes only a philips screwdriver) and reinstall it yourself, the electronics shop shouldn't charge you for more than an hour worth of time. The caps would be about $10.

Here's a photograph (thanks Don Crawford).

Power supply


Good Day,
Why not try to fix it, it's hard to find a board and easier to repair. Try these; 1). CHECK IC700 PIN 20 (AC-OFF) FOR 0 VOLTS DC. IF HIGH, CHECK FOR LEAKY D980 PART # 264P045040 ON THE MAIN PCB. 2).
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/device 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. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

Mitsubishi Vs-50605 TV dead


First thing on a Dead VZ7 to check is the solder connection at the yokes "DY" Connector. Then Check C411 2200uf @ 35V
Then C412 10uf @50V. Then Check IC700 Pin 20 for 0VDC any voltage other than 0VDC on that pin means Diode D980 is leaky.
Hope this helps. If you need anything further let me know.

Fix convergence issue first = bowing / distortion will go away.
Requires changing large STK IC's and possibily a pico fuse
