Hi, Unplug the unit from the outlet for at least 1 hour and check if the symptoms persists. If yes, check if the unit can give an error code by following the steps below. - Power on the unit and wait until the initialization takes place. - Press the front panel "Input" and "Menu" buttons at the same time and hold it for 5 seconds, it will activate the error code mode. LED flashes a two digit error code. Example, if the error code is "22" the LED will flashes two times pause and then flashes two times and will repeat the error code for 5 times. "12" means no error has occured. Please let me know what will be the result to assist you further. Regards,email@example.com
May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.
Please check if you can access the "Self diagnostic screen" by following the steps below. - To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from. Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code. Regards, Jdvillanueva
Mitsubishi > VS XXXX this model is famous for fluid leaks. each projector
tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.
We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.
You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
According to the Sony Service Manual for the PFM-500A3WU, 12 22 means
either the Plasma Panel has failed or the Power Supply has failed. 12
means "warning decrease of panel high voltage" and 22 means "warning of
decrease of middle panel voltage".ve had a look on other forums and someone as narrowed the 12/22 code
down to the (ic102) its only outputing 5volts its something to do with
the (b+ power supply)
