    Problem is Identical to jthomas4765. Use the remote and manually to turn the TV on and it turns off in approximately 3 to 6 seconds.

Good Day;

One of these may be your problem:

1. SHUTDOWN CAN BE CAUSED BY NO VERTICAL DEFLECTION. SINCE THE VERTICAL CIRCUIT IS POWERED BY THE SWITCHED POWER SUPPLY THE UNIT MUST BE TURNED ON TO TROUBLESHOOT THE CIRCUIT. THIS CAN BE ACCOMPLISHED BY TEMPORARILY DISCONNECTING THE VERTICAL INPUT TO THE X-PROTECT CIRCUIT. ** TO PREVENT DAMAGE TO THE CRT'S YOU MUST UNPLUG THE CRT PCB'S. ** TO DEFEAT THE X-PROTECT CIRCUIT, UNSOLDER D4A1 LOCATED OFF THE COLLECTOR OF Q4A1. IF THE UNIT POWERS ON AT THIS POINT, YOU HAVE CONFIRMED A VERTICAL FAILURE AS THE CAUSE FOR SHUTDOWN. ** D4A1 MUST BE REINSTALLED IN CIRCUIT TO PREVENT CRT DAMAGE. ** 2.CHECK PIN 1 OF IC401 FOR 10.7VDC. IF LOW OR MISSING CHECK FOR SHORTED D4000 LOCATED OFF PIN 1. (PCB-MAIN) D4000 PART #264P487030 3. CHECK PIN 8 OF IC401 FOR 27.7VDC. IF MISSING CHECK FOR OPEN D955 AND L961 AT S1 TERMINAL OF T902. (PCB-POWER) D955 PART #264P102040 L961 PART #411P012010 4. CHECK FOR DEFECTIVE IC401. IC401 PART #272P239040, OR INSTALL PT# IC-401, THIS KIT CONTAINS CAPACITOR C920, D4000 AND IC401. BE SURE TO MOUNT C920 ON FOIL SIDE OF PCB. 5. EXCESSIVE 130V SUPPLY. CHECK C911 47 UFD 100 V AND C914 47 UFD 50 V, IN THE IC900 CIRCUIT. Good Luck, big IRISH.

Mitsubishi Projection TV Model #VS-50603 will not turn on.


The TV is going into a "protect mode", the micro-processor has sensed a circuitry problem and has shut the set down so that no furhter damage can happen, you will need to have the TV serviced by a Mitsubishi tech. Good luck !

there is a protection circut that will shut down the tv when it detects a failure in one of the components , when components heat up to much they go into thermal breakdown, the part that is heating up and failing is getting worse , so it will need to be test to determine which one

Mitsubishi VS-5071 rear projection turns on, has audio but no video


That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.
