After it shuts off, you need to get a code from the tv by pressing the menu and device buttons together for 5 sec. A code will flash at you made up of 2 digits. Example. 2 flashes a pause and 2 flashes points to a convergence failure. If this is not your code post yours and I will help you.

    I have the same problem, and the code is 2-1 - X-Ray Protect.

    Any ideas?

    Thanks in advance.

When i turn on my mitsubishi ws-55857 it turns off after a few seconds. should i call a repair guy???? i am a handyman??/ what should i do


Hello

this has two general failures that cause this type of problem... The first and easiest is that when the bulb gets older the tv's start turning off by themselves. Pop in a new bulb and the problem goes away. The second is a power supply issue, and those are generally available on ebay or shopjimmy. If you like the tv, I would find a new bulb ...

Best of luck

When power button is pushed on it clicks "green" for 2-3 seconds and then powers off.


Replace Both of your convergence ICs STK392-570, they are big black ICs.Also resolder all poor connections,look for leaky capacitors.
