Hello,


It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.This will help.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex


When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

My 65 in mitsubishi medallion hdtv 1080 wont turn


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.

Mitsubishi Medallion Hd1080


Try to access the self diagnosis feature, by pushing the input/device and menu buttons in on the set itself and hold them both in together for 8 seconds to see if the led will blink a two digit code. If it doesnt that means the processor isnt powered so therefore its a standby voltage issue thos are usually easy to track down Try the proceedure to access the diagnosis feature then let me know the results.
