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?

there is a possibility that the power switch capacitor has bubbled or leaked a remedy is to unplug the unit from the outlet for at least an hour then try to power it back on.

i will try to look for more information about other work-around's or which of the other parts are defective or almost defective, that is causing the problem.

I have a RCA R56wh78 projection power button flashing green.

Thats the classisc sign that the CP150, CP114 and CP120 capacitors need replacement. You can get the repair kit called CP150, CP120 and CP114 at which contains the capacitors and the CD with step by step instructions on how to do the repair.

The tv wont turn on. the red light blinks 9 times.

There is a problem with one or two of the diodes on the G board.
Zero Crossing Detector 9 times 9:0 or 9:1
Probable cause • D6116 or D6301 is open (G Board)
symptom • No picture
I hope this helps and good luck!

Power and tubes power up then turn off

Depending on where you got STKs even New can still be bad! Also what was STKs # that was in TV? If 110s,120s.150s use 180s if 020s use 040s other wise use same number on STKs.STK392-560 use same/ STK392-570s Use same.

Tv wont turn on blinks 9 times then 1 time

I was inform that it could be a sensor (bad diode), you have to get a multimeter tester and test the diodes and if current flows from both sides then replace that diode.

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.

Sony KDP-65WS550 flashes when you try to turn it on

No the DLP units can flash more than 8 times. 9 blinks mean Zero Crossing detector which means diode number D6166 or D6114 is open they are on the A board.Let me know if you need any further info.

Trouble code: Standby LED blinks 9 times

Try pushing the buttons on the remote and let me know what comes up on the screen if anything.
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
