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.

SOURCE: Mitsubishi Diamond Series T.V.

When a tv (Rear proyection) shows this coloration is the meanning that the red color is not there (the red color is generated by a red CRT). Now it can be really bad not having the tube working but before conclution make sure of this: (and if the red color gets back then the tube is ok)

  • is this condition the same in all inputs? or the picture looks ok with a different video source (VCR, DVD other)
  • are the menu letters same as the picture looks or are they fine?
If we cannot see any red color back with this testing, still chances that a technician find an electronic problem that make the tube to be off. so don't rush conclusions and get to the end to save the tv with out replacing the red tube, but if all was done and nothing then the tv needs the tube replacing.

Sounds like your TV is overheating. How dirty is the filter on the side? Is the fan on the back turning ok:? Does it look real dirty? Is so, a good cleaning is in order. Also, there is a fan under the lamp. Can you determine if it is working...the air flow may be obstructed (from the clogged filter) and it takes some additional time to cool.

Sounds like you have a cooling issue. Do you notice if the fans inside the back of the tv are running? If not then it's overheating and turning itself off to prevent further damage.
Also The next time it happens, before you just turn it back on, press the INPUT and MENU buttons on the front panel together and hold them down for at least 6 seconds. This should cause the front LED to flash a 2 digit code. If it flashes once, then twice, then pauses and repeats, it means that the TV's computer didn't detect a problem.

Mitsubishi black diamond tv


Might be a bad CRT or bad video output IC that drives the CRT that would cause this issue.
