SOURCE: i had a power outage and now the tv will not power


You may have a blown fuse. Unplug the TV and remove the back. Look for a small fuse near where the power cord goes in.
If it is blown that may be the problem.
Use a magnifying glass to read the AMP rating.
replace the fuse and plug it in. If the fuse blows again you need expert repair services.

If the fuse doesn't blow then try to turn it on.
If it turns on then check the operation of the TV.

If the fuse blows again or the TV won't work correctly then you need expert repair service to fix your TV.

You may be able to have your household insurance pay if it is damaged by lightening or a power surge.

SOURCE: The power outage went out yesterday and my tv wont turn on

Most likely it is capacitors on the dm board that have gone bad. This is a fairly common problem and has been addressed on fixya many times. If you know someone who is good with soldering and technically incline or even an honest electronics guy then the repair is quite cheap. If you have any other questions please let me know. if its not the capacitors on the DM supply then its a problem with the whole DM assembly that part usually is around 300$. So you may want to consider purchasing a new tv. Trying the 7 caps on the dm supply board shouldn't cost much if it takes anything more then that. I would sell the tv on craigslist or ebay and recoup as much as you can towards your next tv.
thank you,
Thank you,

If it is 2,4 you have a problem in the vertical circuit and I would suggest you first look for any signs of glycol there.

No red on mitsubishi ws-65908

DTV is HD input but look to see if red lens is lit====set does have a hard reset which might cure it if it is a issue---it is based at the exact model number, a four digit code and the working Mitsubishi remote control.

1 Answer

The on/off relay does not stay engaged

Based on model number listed here:

If set powers up and green light comes on and goes out a few seconds later:

Press and hold menu and input (source) buttons at same time on the front of the set for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks, 2 blinks, pause and repeat it for a total of five times.

If the set has been unplugged you will have to plug it in and turn it on letting it fail (unplugging will clear all errors).

Let me know error code and I will explain--2,2 is most common and most easy one to fix.

I have a WS 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.

My mitsubishi tv model ws55908 will just turn itself off after I have been watching it. It could be as soon as 1 or two hours or 4. it does not happen all the time I can go a month without it happening...

This TV has a self diagnosis feature. When the set fails, push "menu" and "input": buttons at the same time and hold them in for more than 5 seconds. Watch the front panel light. It will blink two numbers five times. Get back to me with the numbers.

Mitsubishi WS-55511 Problem TV out - Getting only continously blinking green light on the front-panel

I had the same problem with the blinking light on the front of the TV and it would not power up. I read all the problems everyone was having and thought I was going to face a huge repair bill. The service guy came out, pulled off the front panel where the speakers are and disconnected the circuit for the front display panel. 3 1/2 minutes in my house, $90 service call. Apparently, when you give the TV too many commands at once, it's safety feature is to"shut down and lock up". He mentioned also that sometimes when these sets get to be about 4-5 years old, the wires in front can "leak" causing a shortage and then locking up the TV. I keep the circuit unplugged and operate the TV solely by the remote. Give it a try, what can it hurt!! Hope this helps.

Power went out, tv won't come on

If you are lucky, it's only a blown fuse, but with a blinking light on the front, this is doubtful. I would pull the back cover anyway and check the fuse. If fuse is ok, then normally if you have no sound and no picture, you have a blown "horizontal output transistor". Look for the big wire (usually red) coming from the picture tube to the circuit board. The red wire goes to a large object on the circuit board called the "flyback" transformer". Usually very near this transformer you will find the h.o.t. (horizontal output transistor). It will normally be mounted on a silver piece of metal (a heat sink), about 2 or 3 inches square or possibly rectangular. The transistor has three pins coming out of it and is probably the largest transistor you will see that has only 3 pins. The upper portion of the transistor will be clamped (or screwed) into the metal heat sink. You have to desolder the h.o.t. and replace it with a new one. The h.o.t. usually costs only about $10.00. If the fuse and h.o.t. are good, then the "flyback" is probably bad and they run from $25 to $100. If the TV is worth only about $200, then replacing the flyback is not recommended, because there is no guarantee that this will solve the problem. Keever.

Projection red is above other colors

Look in your menu for something called "horizontal static convergence" or just "convergence". Adjusting this will align all three tubes electronically. If physical adjustment is needed, then you have to do this manually inside the Tv. keever

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
