The set is going into shutdown because a problem has been detected inside. This prevents further damage. It could be anything from a shorted horizontal output transistor to a defective convergence IC. Without examining the board and taking measurements inside, it will be difficult to near impossible to diagnose this remotely. I would suggest that you invest in a detailed repair estimate that shouldn't cost more than $100 and report the results here. With that info, we should be able to walk you through the actual repair.

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?

I am having a problem with my Mitsubishi medallion HD1080 . I turn it on and it turns off right away. It won't stay on for 3 seconds shuts off by its self. Can somebody help me?


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.

Hope this will helpout...

I have a Mitsubishi medallion 65 and it keeps turning off,


Dear Sir,
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 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)

1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 PART # 283P044020 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. I hope this helped.

Good Luck, big IRISH.

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.

Powers on and off.. wont stay on


Check to see if all the fans are running. The fans are needed to cool the engine off while it is running. Double check the fan for the DMD board for this fan is a common problem.
