Question about Projection Televisions

Mitsubishi WS- 65809 65 INCH

The power in our house went out for about ( 2 ) seconds. This particular TV set was not on. But now the green button on the TV keeps going off. This is the only set with any problem since the outage. How do I resolve this problem?? Thanks in advance....DD Model #WS-65807.
Audio is o.k. but no images. Input label shows double letters and concaved. On "menu" selection, all letters are doubled and concaved.

    Thank you so much for your interest in helping someone in need.

    Called in Mitsubishi authorized service rep and he said exactly what you described, fluid is leaking on one of 3 circuit boards on the bottom and needs to be replaced at $600. He said it should correct the problem and if it doesn't, control circuit (looks like an steel enclosed tower in back of these 3 CBs, sitting in the middle) needs to be repaired. He said the first step is replacing 1 circuit board where fluid was present.

    I'll keep you posted.

    Thanks.

    Just talked to the Service Rep and he said it's not a question of cleaning, it's corroded and he cannot get the replacement part from Mitsubishi. Horrible news is that this TV is worthless. He said the fluid leak is repairable not the signal board. I hate to dump this TV.

    Any suggestions?

    Thanks again.

    Unlike what service rep said the signal board is not corroded through anywhere and no fluid visible. But he showed me a jell-like white substance when he was checking inside. Bottom left-hand side of picture where orange loop is the place of said corrosion but the black mark on the picture above is where a couple of capacitors plugged in. As far as I can see the signal board is clean and no sign of corrosion. He also claimed corrosion is under the signal board and only cure is to replace it. He also advised me it's no longer available from Mitsubishi. What it means it lasts only 5-6 years for a big projection TV and not servicable? This 65" TV was not much used in the last 5 years. I had an excellent experience with 19" Mitsubishi TV for 15 years and was going strong.. I'm sorry about all the gripes. I'm located in Washington, D.C. area. Can anyone recommend me with a reputable repair place? I hate to give up any hopes. Thanks.

    It seems like MEK is a cleanning solution. Where can I get it?

    Any tips you can provide me how to clean it with MEK?

    Thanks.

  • mx-4h Sep 12, 2008

    I tried MEK with the same results and I'm going to ask Mitusbishi for their input. I cannot imagine a world congolomate and a reputable company such as Mitsubishi manufacture a pricey product last only 5-6 years and drop the ball. I even bought an extended warranty for 5 years which expired 1 year ago. What if I still have warranty and no replacement parts?

    Again, thank you very much for all your prompt responses trying to get this one running. You are the best internet-based help I ever experienced. Keep up a good work!

Sounds like you have a couple of problems here. The double image would be convergence but that should not cause a no video symptom. I would check to make sure that you cable box/sat box is working correctly and that you are on the correct input.
If you still have no video then another cause for multiple problems in this model would be a fluid leak, I would take the front off of the set and look in with a flashlight and see if you see any liquid on the boards. This should be on the big boards in the bottom of the set not the 3 boards hanging off the tubes. If there is no fluid on the boards and you still are having several problems then you may have had a weird surge issue, i would have to say it would be affecting the signal board which i just check on mitsubishi's website and they are showing 0 available but they do not have a No longer available notice so they just might be out of stock right now. If you need more info please let me know

    He said the board needs to be replaced? Now sometimes this is the case, but did he even try to clean the fluids off of it? At my company when we have a fluid leak we first clean it with MEK and try to get the set up and running (this saves you the cost of a new boards). Also is he going to do something with the tubes to prevent a future leak? These are just a couple of questions i would ask him. Let me know if i can help more?

    If you would like to try and tackle it yourself I would need to see some pictures of the fluid on the board. Not many techs are qualified to do the real tv repair work they are more of "board changers" so we may be able to clean up the board and get the set running. let me know what you would like to do?

    I do see what looks like some corrosion on the board there I have circled the areas i think i see, its kinda far away so its hard to tell. From what i see i think this has a good chance of being repaired. A good wash with some MEK and that board might run. If you would like to find a servicer use this link http://www.nesda.com/locator/state_searc... these are all members of NESDA and should be reputable servicers.

    Your about to get into a very large project, it can be done but not easy for a first timer.

    MEK is short for Methyl Ethyl keton, you have to be very careful with this as it smells horrible and will melt almost anything. You should be able to find this at any home improvement store or paint supplyer. I would not recomend using this product in your livingroom. You may want to try rubbing acohol first because its not as harsh of a chemical.



    In order to clean this board properly you should put a very small amount on a toothbrush and rub it around the corroded areas then let it dry and repeat this several times. Sometimes removing the board from the set is nessesary to clean it properly.

    Let me know if you need more info?

I have a mitsubishi ws-65315. When I go to turn the tv on the green power light comes on and you can hear the tv click on, but seconds later shuts off.


this model has a self check, when green light comes on and then goes off. Push and hold both the Menu and Input buttons 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, a pause and then repeat it several times.

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

I have a mitsubishi 1080 series tv. I turned the tv off and then I went to go turn it on, now the little green light on the tv stays on for 2 sec. and then goes away without the piture ever coming on.


A hint--if the green power light comes on for a few moments and goes off do the self check this set has.

On the front of the set press and hold BOTH THE MENU AND INPUT (OR DEVICE) BUTTONS BOTH FOR AT LEAST 5 SECONDS. Release both buttons and look at the power button.

If this is the case the power light will blink a two digit error code--most common in this case is 2 blinks, a pause and 2 blinks--it will repeat the code up to ten times.

Let me know if you find an error code or the power light just blinks and never stops.

If this helped you rate this solution as I do this here for free.

Power went off in house when it came back on the green light on the front panel keeps blinking will not stop Mitsubishi Bigscreen model ws- 65909


I've got a 65535. When this happens, you can sometimes press the On-Off button for 10-15 secs until the light goes off. If that doesn't work, then unplug the tv for 30 seconds or so, then plug back in.
These sets are known to have power supply issues, and the blinking light may be a coincidence to the power supply failure. It's fairly easy to repair if you know how to solder.

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.

Press power button green light comes on.But no picture no sound,


I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

TV power will not stay on.


Not worth to fix.Either power supply,sensor or convertion board are too costly for the part.Buy a new TV.

If your TV is not powering on you probably blew the power supply. These TV are sensitive to power surges. Be sure to use a power strip with power filtering technology (different from a surge protector) costing around $80.00
