Question about Mitsubishi WD-52725 52". Rear Projection HDTV

1 Answer

Tv won't power on

We had a slight power failure(glitch?) and the tv turned itself off, but the timer light won't stop blinking(fast). I've tried the system reset, but the light continues to blink (won't stop). I've turned off the power strip and left it off for 10 minutes, when I turn the power strip back on, the light starts blinking again.

Any help will be greatly appreciated.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.

TV shut off while watching and won't come back on


It seems this is a self diagnostic function. the official sony codes are as follows

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps

Tv turns on then off


hold the menu and input buttons simultaneously for 5 seconds. the tv will blink an error code
Error Code Probable Cause
12 Normal Operation - No Error Detected
21 X-Ray Protect
22 Short Protect - likely convergence IC failure
23 Loss of Horizontal Deflection
24 Loss of Vertical Deflection

Fast Blink for 70 sec. After AC is applied = Normal - DM μPC is booting up
Fast Blink (doesn't stop) After AC is applied = TV μPC is running, but DM failed to boot up
Slow Blink Set is Off = Normal - Timer is set for Automatic Turn ON

TV won't turn on


There is a failure in the scan amplifiers, and or the power supply. This will require trouble shooting by an experienced TV tech who has access to the service manuals and know the set.

There are many components in the set that can cause this type of failure.

Did you not take an extended warranty???

This type of repair is not low in cost to have done.

Green power light will not stop flashing and tv will not turn on or off


You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.
