Error Codes; Self Diagnostics - Mitsubishi WD-52627 Training Manual

Self Diagnostics...When an abnormal condition is in-
dicated by the front panel LEDs. Or, when the TV turns
On and then shuts Off, the Self Diagnostics help isolate
the problem. This is similar to the Self Diagnostic fea-

V28 ERROR CODES
Description
Description
1) With the TV Off
2) Press and hold the front panel "MENU" and
"DEVICE" buttons for 5 seconds.
3) The LED will flash the Error Code indicating
what caused the TV to shut Off.
4) The Error Code will be repeated 5 times.
When the LED stops flashing, the mode is
automatically terminated.
Reading the Error Codes
The Error Codes are two digit numbers.
The LED:
• Flashes the value of the most signifi-
cant digit (MSD).
• Then there is a pause.
• Flashes the value of the least signifi-
cant digit (LSD).
• The Error Code is repeated 5 times.
Example: If the Error Code is "32", the LED
will flash three times, pause, and then flash
two times then repeat the sequence 5 times.
If the technician is still uncertain of the code,
repeat the procedure.
After the error code is known, troubleshoot
the area indicated. For instance, if excessive
temperature is indicated when the set is known
to be cool, suspect a failed sensor.
