Sound But No Picture Shuts it's self Off

Hello!
I have a Mitsubishi WD 65831 and this morning I turned it on and I have sound but no picture and then it shut off within a minute. When the lamp goes out will the TV shut it's self off? Or do I have another problem? I would like to know if you think just replacing the lamp will fix it? thank you for your help!

Hello... About the only thing that can cause this symptom is a bad lamp. Most of the time, you can look at the lamp and tell if it's bad. If it's not shattered, it might have an odd bulge at the base of the reflector, or a gray circle on the clear tube at the bottom. I hope this helps!

SOURCE: Replaced lamp and now can't get a picture

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

You most likely have some faulty capacitors on the power module. You can easily identify a bust capacitor. They will have swollen tops. Here is a sample pic:

Check the specifications of the faulty capacitors, and getthe replacements from your local electronics shop. If you are comfortable withthis, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out thedefunct capacitors. Once that is done, solder in the new capacitors carefully. Ifare unsure how to do this, try to get a friend who knows this kinda stuff to doit for you, or get a qualified technician.
Warning: If you do not have a background inelectronics repair, or are inexperienced, get a qualified technician to do itfor you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

If you want to go in for a long term solution, youcan easily replace the whole power board. You can get spare from HERE.

Hope that helps!

If you hear a whining noise, the odds are it is the color wheel, the bearings are bad in it and will need to be replaced as a whole unit, kinda pricey, my suggestion, sale the bulb and all boards in it and which should fetch about 400+ and invest in a new TV, a color wheel is pricey unless you can find a deal

sounds like the projector globe is gone. i think you will need to replace it. if you are lucky there should be a pannel on the side or rear of the tv that allows you to replace the globe. pricey though.

good luck
