My Mitsubishi when I turn it on it shuts itself back off

SOURCE: My Mitsubishi turns off automatically...

I had the same problem with an RCA, check your sleep mode settings on it, it may have defaulted to 1 min, so it cuts off when it cuts on

SOURCE: Power turns off automatically

Same w/ mine.  Repairman said they turn off auto to protect the set no matter what is wrong.  Take it to be fixed.  Mine was right at $100.  Works great again.

Dear Sir,
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. I hope this helped.

Good Luck, big IRISH.
