Mitsubishi TV; Powers on for 5 seconds with raster and audio and shuts down, does this every time I try to power on.

This model does have some issues, you can try on it to either remove it and a box if used for power for several minutes and then power back to see if that helps.

Soft reset with set on should (using original remote) be Menu, 1,2,3 and enter.

If you are getting at turn on source and back ground is all blue the set will shut down rather quickly;

I have a suggestion, if it works fine, and if not it will not hurt anything.

with original Mitsubishi remote turn set on and then Menu, 1,2,3, enter.

This is the soft reset that most of these sets have (cannot be sure since Model number above is correct?)

The reset button on the front (if it has it) just shuts the set down and reboots the DM unit inside.

Most of these sets when it is pressed the green light will blink for about 70 seconds and go out; that is the DM unit rebooting and the soft restart is something else.

Let me know what you find before you rate this information.

You might just want to try to force it to shut down by holding the sleep wake button on the top of the iPod for about 5 seconds. After it powers down, wait about 5 seconds, then hit the power button on top for about 1 second to turn it back on. After it powers up all the way you should be able to unlock your iPod.
Hope that helps!

Check the error code by holding the menu and device buttons for 5 seconds and reading the number of times the power led flashes between pauses. This has to be done after the set powers up and off.

2.2 is a common convergence problem.

Ur power ic inverter board is dead.
U need a new one.

set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

DLP Projection tv, Models WD-57731, The tv powers on but the screen remains black, the audio comes on but after approximately 30-40 seconds,the audio starts to skip and then the entire tv system shuts down. I reset it a few times but that doesn't change the problem

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!

I just took my Mitsubishi WS-65315 65" in to be repaired for the same problem and was told that it needed a new main circuit board part number 930b899005 as was told they wanted to charge me $1100.00. So I told them not to do the repair and picked up my tv and found that same part at Sears parts for only $225.00. Some of these TV repair places are theifs.
