20 Most Recent Mitsubishi WS-55809 55" Rear Projection Television - Page 9 Questions & Answers

There can be several causes for this, few of which you can do anything about. However, a few things to try.

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

Good luck with your problem...I hope you can work it out.

most likely a blown transister near the bulbs or color wheels causing it to turn off once they start drawing juice I would consult a local tv repair store and see if they have any exp. or parts for yours

Sounds like you have some solder problems on your deflection board. If you're up for it, you could fix that yourself with some solder and a soldering iron. Just take the back off, and look for the board with 2 of these on it (numbers may be different).


Remove the board carefully noting where you unpug things (take photos if needed). Then reflow the solder joints on these parts. I hope this was of assistance, best wishes.

Did you try connecting directly using a HDMI or Component cable? Also did you check the connections which is the most common cause of this problem?

Sai.

This is a internal overload issue need a TV rent-a dude.

If the error code/blink code is 22 - its commonly a convergence failure. If its fast blinks with no set pattern its normaly a DM module problem. Both can be fixed with kits from www.TvRepairKits.com

I would check the flyback transformer on this unit something tells me that might be the issue your having. Warning tho if you do not know how to repair this TV check it into a shop as the flyback transformer has high voltage and could be fatel up including death if handle the wroung way.

Is there any sound once the picture goes out? Or no picture, no sound and no blinking light?

These chips are the culprit:

Replacing them requires a lot of soldering and a knowledge of circuit boards.

Is the Tv worth saving? is it bright and clear? was it good (when it worked?)
if the answer to all of these is yes, then you have a few choices. If any of these are not true, then you should just get a new tv.

Your choices are:
If you are good at soldering, then you can attempt to replace the IC's yourself. (with all of the parts handy, it should take 1 hour)

If you aren't good at soldering, then you can have a friend do it for you, or you can have a mechanic fix it. (tell them that its the convergence IC's that went bad. (pay no more than $200 for the job).


These go bad on almost all projection tvs eventually. They overheat and burn out, causing the screen to go in/out of alignment and make wavy lines.

If you need more info on IC's, contact me.

The red crt tube on your tv is going, or you need more optical fluid for the lens. Crt tubes typically run for $150-$300, and a fluid refill should be less than $100. If the tv isn't very clear or bright, even when working right, then consider just getting a new tv. These are costly to repair and will eventually begin to have more problems.

Contact me for more info.

I assume you bought it at TvRepairKits.com. Its printed on the sheet in the kit. Or go back to their site and ask for the instructions. Include your last name and zip code so that they can verify you ordered a kit.

Sounds like the switch mode power supply has popped, check with cpc or farnell to see if your model has a power supply repair kit available, normally they cost around £40 and will require soldering skills. Don't touch it if it's still in warranty.
Hope this helps

Convergence is dead.U know how to solders?Must replaced the 2 Convergence ICS,and all it resitors.Buy a convergence kit at Tv repair World.com,Tvrepairkits.com to repair it ur self.The shop will cost U 300 for parts and labors.

All these sets do have a hard reset---not the reset button on the front of the set---it will return the set to the factory original condition it was when new in the box--it will not affect the convergence as that is stored in a separate unit--the DCU (digital convergence unit).

It is accessed with an original MITSUBISHI remote.

You can try it if you want:

ACCESS CODE FOR WS65809 IS:

menu-0,1,7,0 enter

There are 3 hidden menus in the set--this is the Option menu

You will see either reset or option etc and highlight it with the remote and hit enter. Set will shut off and should come back on channel three in the air band--any labels you placed on inputs will be gone and set will be in air band--you will if on cable have to change it to cable band and auto program etc.

Let me know what happens and if you have questions I am here to help.

Although that's not a lot to go on, I would hazard a guess that the Convergence ICs have gone kaput and need to be replaced. If you are handy with a soldering iron, you can do it yourself.

Chips run about $15-25 a piece. Have plenty of thermal compound on hand and slather the backs of the ICs and the heatsinks with it.

One surefire thing you can do is to check the 5amp fuses on the main and power boards to see if any of them blew. There are two located on the same board as the ICs that--if blown--definitely point to the ICs as being the culprits.

2,2 is error code for short protection---98% of the time it means one or both of the two soldered in pico fuses that protect the convergence circuit are blown.

The repair involves getting the middle circuit board out of the set, replacing both STK-392-570 CHIPS and either of the fuses involved.

I will post photos here of the fuses and some resistors on the same board that likely are good but easy to test.

Then I will post the step by step instructions in several parts as they are too long to post here in one shot.

Read the instructions and decide if you can do the repair--ignore the true/false stuff--its there because they were composed in MS Word.

Photos and then I will post the instructions in a minute.

Ic looks like this but number will end in 570 and your model uses two of them.

Set comes on and shuts off within 5 seconds?

I am expert on this set.

Regardless, my answer stands. It needs repair by a qualified technician. Rates vary by area. Make telephone inquires.
