Question about Mitsubishi WT-42311 42" Rear Projection Television

1 Answer

Turnes off, sometimes in a short period, and sometimes it will go for hours.

After a short period it will turn back on. As a rule once it starts turning off it will keep it up for the night, but I only try to turn it back on a few times. I have had the set around 5 years with no other problems.

Picture turns green ,usually within 10 minutes of turning it on.It will sometimes go back to normal color but generally returns to green.This happened when the set was much newer and Sony replaced all...

Green Tube maybe trying to short out or you can try adjusting screen drive to the Green Tube by turning control down a notch, Sony had a bad run on these with alot of Bad Tubes.

TV Turns Off Automatically While Watching

Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.

After my 70" tv is on for a period of time, it turns off and won't come back on for a while.

Good Day, Connie ss;
The next time the TV turns off try this:
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/device 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. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB. I hope this was helpful, good luck, big IRISH.

Mitsubishi VS-50707 shuts down sporadically

you can do a self-diagnosis test by pressing the menu and input/device button on set for 5 sec and see what error code it gives you. Count the blinks followed by a short pause then more blinks. This is the error code.

Loud whirring. Not the fan.

The fan noise is normal on this set. The lamps are cooled via this method. Your users manual explains this issue..and it is the fan as you can see it slows down after the tv is switched off..

Whirring noise. No other problems.

Sounds like you have a noisy color wheel. Very common on all Samsung DLP`s. The part # is BP96-00250A for model HLN5065W.
