Mitsubishi WS55809 - tv won't stay on

I have a 55 inch Mitsubishi WS-55809. Whenever I go to turn the tv on, it comes on for approx. 3 seconds and then it shuts itself off. The screen doesn't even have enough time to come up. I called the help line and they told me to unplug it for 15 minutes and then try it again. I tried disconnecting the tv from the powerstrip and plugging into the wall directly. I tried disconnecting the tv from the cable box. None of these fixed the problem. Let me know if anyone has any other ideas. Thank you!! Bob

    Dan, Thanks for your response but I really don't have any other details to provide. It was working fine one night. The next day I tried to turn it on and it wouldn't stay on. I'm not sure what to do at this point. I called a service guy and they will cost me $85 just to come out. Thanks, Bob

    Dan,



    I had a tech come out this afternoon. He ended up running some tests on various components and didn't find any issues. He informed me that he would need to take out the main circuit board and take it with him to further investigate. Even though he doesn't know what is wrong with it, he told me that it would run anywhere from $375 to $450 to fix it. I'm not a technical electronics kind of person that feels comfortable fixing this tv on my own. It looks like I might be better off getting a new tv.

    Let me know your thoughts.

    Thanks,

    Bob

    I have the same problems with my Model WS-55819 - have blown out the dust, just in case it was an overheating problem, with no effect -- please let me know if you find a resolution richkat2006@clearwire.net

    I have the same problem with my mitsubishi shutting off after a few seconds. It had done this before on several occasions but evenually started working again. Need help! Kerry

  • Mortymer Jun 05, 2008

    Hi All,

    Same exact problem...6-7 year old set and it will try to turn on for about 1-3 seconds (no picture) and then shuts itself off.



    Worked fine for the past 6 years, but I sure imagined it would last a heck of a lot longer than that!



    It will be the last Mitsubishi product I ever purchase.

    :(

    My Mitsubishi WS55809 - tv won't stay on. Unit turns on for 2-3sec. and then shuts off. any ideas?



    i have also tryed to clean the boards.

  • Steve Tucker Jul 06, 2008

    My Mitsubishi WS-55809 won't stay on. It turns on for about 2 seconds and then there is a fairly quiet click and it turns off. (Same using either remote or button on front.)


    I have also tried blowing out the dust. Someone talked about fuses - I only find one fuse and it is on the AC power input line. If I remove it then the TV doesn't come on at all. When I replace it, the behavior goes back to what I've described above.

  • lbaker4 Jan 28, 2009

    My Mitsubishi set worked fine one day, the next My son pushed the power button and NOTHING. It will not even try to turn on?? Is it finally dead- it is an older set. we just use it in the family room and really don't want to get another one. how do you check fuses in it ??

  • Palsherrie Feb 02, 2009

    We had a similar problem with ours we haven't watched it in 6 mos I took the back off vacuumed it out and one fuse on the center main board in the back of the tv there is a fuse # F9A05 that fuse was burned out and I put a jumper wire on it and the tv came on and stays on we have been watching it for hours now. If this works for you I would have the correct fuse put in it don't leave the jumper wire as perment fix Our TV is a Mitsubishi HDTV 1080 55in rear projection Ours has a diagram on the right side inside the back cover that shows fuse locations.

Check the fuses soldered on the board, mine just went out and i have two blown fuses. A 5 amp and a 3 amp 125 volt. Also you can check the diagnostic mode hold the menu and the input on the tv for 5 seconds. If the light blinks twice and then 2 more times that means there is a short (bad fuses)

There are a number of reasons for hte set to sut itself down. Usually, the standby light blinks when this happens. It could be as simple as a bad connection or a more severe problem. Please try to post any details about the behavior you can.
Thanks,
Dan

A capcitor is losing it's performance characteristics. Mine is doing the same thing now. This happens to a lot of sets. It's as common as a tuner going out.

Electronics like constant temperatures and humidity. Unfortunately a home isn't going to have that. Also keep in mind that things are built to fail. If they don't then you have to invent something better. Inventing is a lot harder then replacing. It is certainly less expensive for the company.

TVs today usually are good for around 9 years. If they last longer then super. As there are so many different brands now you'll see a lot more inovation and claims regarding leaps in technology to keep you coming back for more. Gone are the days of quality based upon price. Now the price is all about popularity. It's the leming principle. If everybody else is jumping off the cliff then perhaps I should also, lest I miss out on something.

An old woman lives in a small rural community about 18 miles East. She called to complain that her pictures were bad. As a cable guy it was my sworn duty to go forth and see what's up... I looked over the set while the woman told the story of how she had ordered the first color tv in the area. She bought it at Western Auto and Appliance. It had a wooden cabinet and a small speaker below the old dials. She had been watching if for over 30 years. She had given up on the old girl and asked what brand she should buy to replace it. I told her to give me a little more time to look things over. I was really just curious about the set and all the adjustments you could make back then. Now you have to rely on a "technician" to fix it. Well, after giving all the knobs, switches, dials, and buttons a carefull inspection I found one small recessed button tucked away, far from any of the other adjustments. It simply said "RESET" and plain black letters. Could it be that simple?

As if God himself had directed me to this poor soul's home to bring salvation to her television viewing, I could feel the influence of some intelligence, some power, course through my body and into my hand clutching a tiny screw driver. I thrust the insignificatn implement deep in the darkness behind the word "RESET" plunging the smallest of black buttons till it would yield no more. At once an explosision of joyfull praise permiated every sqaure inch of the mobile home's living room. The 80 year old woman looked at me like I was holding a large check from publisher's clearing house. The TV was brought back to life, as if, by a miracle. Somebody sitting at a test bench in a research and delvelopment department within the bowels of RCA. decided that a "RESET" button would be a good idea. For that I am willing to bet, they were fired or promoted out of that capaicity.

So, to those of you experiencing this problem. If your set won't stay on, or if it shuts off as soon as you push the power button, I say to you go forth with credit card in outstetched hand and with the other hand cover you bum, because TVs are really expensive nowadays.

My HD 1080 WS-55809 won't turn on - little green light comes on for 2 - 3 seconds, then nothing. It was fine - we were watching a DVD but had it on pause - the tv turned itself off - then it won't turn...


Hi


Thanks for using FixYa. Error code 2-2 means short protect which is either caused by bad convergence ICs and/or 2 Pico fuses (F9A05 and F9A04). You’ll need to open the back of the unit and replace the parts that have gone bad to resolve this issue.
Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Tv wont turn on


hold the menu and input/device buttons for 5 seconds and it will blink you a 2 digit code
1-2 normal operation
2-3 i believe is short circuit protection = probably a convergence failure
