I hav a mit 65 in tv model number wd 60737 it comes on with the words welcome mit and green light blinks and then shuts off.

Does the led light flashes green continually?

Check if you can access the operational error code. The TV must be in shutdown and then press the front panel "activity" and "channel down" at the same time and hold them for 5 secs.

Led light will flash 2 digit code separated by a pause.

23 - 2 blinks pause 3 blinks

Let me know the result...

Optoma RD50 TV which shuts down on #1 fan failure

This could be a variant of, or a newer (or older) version of the "DMD fan failure" message.

Symptoms I had are, I stop hearing a fan when the message is displayed.
Then the temp LED keeps flashing RED until I either try to turn the TV on again,
Or turn MAIN power off/on again. BUT it repeats when I try to turn the TV on.
The picture appears normal until this happens ( about 15 sec.)

The solution is to FORCE a normal shutdown by hitting the TV off button
before the message appears.
You should see the power LED flashing RED/GREEN (cool down) and then RED (standby).

Have an hitachi 53uwx10ba red light on front is on but no tv

on some TVs, the lights do not turn off so that is not that big of a deal.  If you want to make sure, unplug the TV and then push and hold the power button for about 30 sec.  Then plug the TV back in and that should fix the light if it is stuck. (Pushing the power button wile unplugged will reset the system default!)

Have a Panasonic Projection TV PT-47wx51c. It is currently shutting it self off, then the red light in the front blinks and can not be turned back on until it is un-plugged. Just befor it shuts itself...

can you determine if the led blinks a certain amount of times then a slight pause before blinking again? Let me know as it may be blinking a diagnostic code.
