Hi,
The power supply is cause of the problem. Donot switch on the TV again and again as it could furthur damage the motherboard. If you are not comfortable repairing or opening electrical components its time to take to TV repair mechanic


Thanks

This may be due to some heating problem in your power board
and hence please have a check for bad components.

Kay, the problem is not A DIY and certainly not cheap to fix. If under warranty of any kind claim it. If you recently had a storm and also have home insurance claim repair under FUSION You need to have repair person use the words Fusion on the bill to get paid/

The popping was capacitors on the y and x sustain boards and even the power board. Sustain boards are about $200 each and power board about $170 all up close to $900 for the repair. But get some quotes and try and find Mitsubishi specialist repair people as they will work faster and have the right parts in stock.


Please rate my help++++Thanks for using FIXYA

I HAVE A MITSUBISHI 65 INCH MODEL WS-65411 AND HAS A CODE 23


This error code shows that you have a Horizontal failure occurring. It could be a intermittent solder connection on one or more of the yoke connectors. That is the most common issue with shut down due to Loss of Horizontal Deflection. If you are handy with a soldering Iron and confident in general TV knowledge, you can repair this. If not , do not attempted it. Call a Professional. If confident, unplug the set from power, remove the speaker Grills from the front. Then remove the Center Piece of the front panel. You should have access to the front plate. Remove the 6 screws holding in on and place it aside. If you look at the neck of the left CRT', you will see a 4 pin Plug Connector that goes from the High Voltage Board up to the Yoke . You will need to use a flash light and check the solder connection under that yoke plug. Most of the time it will look like it has been arching. Resolder each of the pins. then move to the center CRT and do the same. After that, repeat it again on the CRT to the right. Make sure that each of the pins you solder are not shorted or have Solder Splashes between the pins. Plug in the set and turn on. Hopefully you will not have the problem again. Reinstall the Front Panel Access plate, Center Piece and Speaker Grills.
Hope it does the job,

I have an mitsubishi medallion hd1080 big screen tv model# ws-55819 getting code 1,2. (hold the menu and input)


Try to unplug set and try it again as if the set was unplugged and then the self check done it will be 1,2 which means NO ERROR detected.

Let me know also what the set does?

TV turns on, then turns itself off about 2 seconds later.


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.

Mitsubishi WS-65313 65 in. TV will no longer power up.


You should call a good TV Tech. This problem cannot be solved by a consumer. The one thing you might try is to unplug it from the wall for a few minutes and then try it again.
