The fact that removing the front helps does not really means anything but is good that you have notice,the age of the set has a lot to do with the problem,I am sure it has many loose conections that need to be resoldered regarless,all sets have many components that disipate a lot of heat and over the years the solder cracks and it forms a ring ,this makes the set intermiatnt until no conection exist any more and it stops working for good.What does the unit do when it shutsdown? does it show a picture with lines that is red ,green or blue and then it shutsdown? or it just goes off? if it shows you a color like I mention it could be the picture tube of that color and the repair will be expensive but it could also be a loose conection somewhere in the power supply or the deflection panel,If you are familiar with repairs ot TV's you can possible take care of it but if you are not familiar with electronics call a qualified technician.I hope you can use this information.

I have a WS 65908........it has the same problum--listed on this site.......power on for 3 seconds...and it said this.... Do the self test this model has: When set shuts off and on front of set power...


Error code 23 on this set means that the Horizontal Deflection circuit of the set has failed. Usually this points to a damaged Horizontal Deflection IC and sometimes the HOT(Horiziontal Output Transistor) as well, not to mention the resistors that are blown when the IC failed. Replacing these parts should resolve the problem.
PS:Note that the Deflection circuit involves certain high-voltage components and prior to repair it is advisable to discharge the high voltage before attempting the repair. You will also need to know how to use a multimeter(to test the HOT and look for blown resistors) and a soldering gun. If you think you can do it yourself, let me know and I will provide you detailed step by step instructions.

Power on for 3 seconds then shuts off


Do the self test this model has:

When set shuts off and on front of set power light goes out:

Press and hold on the front of the set both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will blink an error code: most common is 2 blinks, 2 blinks a pause and then repeats it several times.

This feature will narrow down where the problem is.

Let me know what error code is found and I will tell you what it means.

If this told you something you did not know rate this solution as very helpful as I do this here for free.

The tv keeps shutting off just after minutes of turning it on. We can wait about 5-10 min before turning it on again but then it only stays on for a few minutes.


This sounds like a heat related problem, which could be a faulty chip or a cold (bad) solder joint on one of the PCBs (printed circuit boards). Due to the lethal voltages present inside a CRT type television, it is strongly advised to have this repaired by a qualified technician. however, if you or someone you know is technically inclined, you can try to fix this yourself. Cold solder joints can often be spotted by visible cracks in the solder joints. a through inspection of all the boards could easily identify the problem which can be resolved with a quick tap with a soldering iron and perhaps a little extra solder added to the joint. if that yields nothing, another method is heat/cold stressing the boards while the TV is running. With the TV on, spray small areas of the PCBs with cold spray (or a can of compressed air duster turned upside down) until the tv shuts off. then heat the last sprayed part with a hot air gun (or a hair dryer) until you can get the problem to repeat regularly. inspect the area causing the problem and you will probably find the culprit.

Mitsubishi WS-65908 Error Code 24


If you have an ohm meter, check the resistance from F9A04 to ground, and then reverse the leads and check F9A05 to ground. These supply +24 and -24 to the convergence integrated circuits. The conv ic's may be bad. Also, code 24 usually indicates vertical deflection failure as well. One other check to make.....The pic tubes on this set may leak a few drops of coolant onto the boards. Look VERY carefully for liquid drops on the boards or a green and or white corrosion spot or two on the boards under the pic tubes-near the front of the chassis.

Re:problems


Your TV is probably shutting down due to excessive current draw. Replace the filter capacitor in the power supply and cross your fingers. This will be a large, tall, and round shaped object near the location where your power cord goes into the TV. It has two pins and one is positive and other is negative. Do not get them crosses when installing new part. keever
