TV won't show picture the power and OPC light blink twice together followed by three blinks from the OPC alone.

The main tv Tuner signal board have problems or it is dying or might be dead already.But sometimes this tv will still work and can be used,i have the same tv have the same problems it work for me all the times.By doing this process.Everytimes Power and OPC lights blinks.Just push the remote power switch again for tv to repower the tv power and OPC lights again,have go thought this process pushing power remote switch again have to do this like 3 or 4 times sometimes before the tv to work.Tries websites like Shopjimmy.com or Ebay.com to buy a whole new refurbish main tv Tuner signal board for the replacement.

When I turn the tv on the power light goes green for a couple of seconds then it shuts off and the picture never comes up.

Mitsubishi self check: MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.

Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem

******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.

SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.

IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

Tv shutting off

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

Hi Chi Chu. I just inherited an Sharp lc-c5277un that turns off within 5-15 seconds of power on. No additional blinking lights, no OPC, nothing. It then will power cycle and turn on again and then do the same. I pulled the back panel off and realized that the Antenna hookup has been ripped out of the Main Board. Normally a dead port wouldn't kill something, but based on what you said it sounds like since this is the TV Tuner board it possibly is just causing the TV to turn on/off. Is there any way to verify this before I go and try to source a replacement TV Tuner board?
