Mitsubishi WS-55859 55" Rear Projection Television - Page 4 - Answered Questions & Fixed issues

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

sounds like you need a new lamp

U can go to the menu reset everythings in the audio setting.Unplug,replug an hour later,all the setting it will reset back to factory setting.Ur audio should return to normal.

Failing power supply. Need capacitor replacement

Could be a color crystal that has a loose solder, had repaired one. Or the micro may need replaced. See a tech...give him these hints. Some knowledge will net a couple of bucks saved!

The dm board power circuit has gone bad and would require many capacitors to be changed. This board is a box (metal grey) on the left extreme as viewed from rear next to input connector board. It is not recommended as an abinitio DIY Project. Caps faults are difficult to find and require an ESR meter. Call for professional help and should cost 180 to 220. Check it out at www.fixurtvs.com for more questions and price quotes.

The WS-55859 does not have a "Lamp" it is a 2001 rear projection set with three picture tubes.

Have (if this is the correct model) you tried the self check this set has?


Also do you have this problem on all inputs--tuner, and various rear inputs?

The more you tell me the better I can help you.

Got a IM?

The convergence board or the verticle is bad. needs professional repairs can cost anywhere from $ 180 to 350. Check it out at www.fixurtvs.com.

This is a common problem. Its called a convergence failure.

• Screen Looks 3D
• Colors wont align
• Video may look distorted

Problem #2 CRT Fluid has clouded over. Symtoms

• Dull looking video
• White looking video
• Halos around objects

hello sound like a lot of money

is a power supply overload is normaly a HV Circuit defective, need to be repaired send to repair.

When the tv turns off you should be able to hold down MENU and DEVICE, located on the front panel of the tv, for 7 seconds and get a blink code. This code will help you determine where the problem lies, or at least narrow it down. It will probably be something like 3-2, 3 blinks, pause, 2 blinks, pause; repeated 5 times. Post the blink code and I will help you further.

bill! any time that you have power turn on issues, you should make sure that you have the proper ac supply voltage at the wall outlet. plug in a lamp at the same outlet as the tv set!. if it works unplug the tv set for a few minutes to attempt a reset of a possibly bad turn on relay or power circuit. try turning on the set by the power button on the front panel. then try using the power on the remote control. each time listen for a click of the power relay and static build up for the high voltage circuits. if you have niether! unplug the set and open up the back bottom panel and check for a open fuse any where on the the circuit board. now bill put on some rubber dish washing gloves before you attempt to replace any fuses upon reaching onto the circuit board suface area. there is a danger of electric shock! at the projector picture tubes an the flyback tranformer areas. if you find any blown fuses and intend to replace them, they must be replaced with ones of the same voltage and amperage rating or your could cause a fire and burn up your set or your home. if the fuse at the ac line cord circuit is not blown ,then you have a open on short circuit in the high voltage section of the set. replace the blown fuse and power of the set again, if it should blow the fuse then you need some professional help unless you are familar with testing and changing out the horizontal output transistor in which maybe causing the short.

Please do the self check this set has:

When the power light comes on and goes out press and hold both the MENU and Input (also called Device) buttons at the same time for at least 5 seconds and then release both buttons.

The power light will blink a two digit error code--for example--2 blinks, a pause and 2 blinks.

Let me know what error code you find and I will tell you what it means and what may actually be the problem.

get a real tv

THIS IS MY STANDARD ANSWER TO THIS QUESTION==SOMETIMES PEOPLE DO NOT TRY THE EASY POSSIBLE REASON--IF YOU HAVE ANY QUESTIONS LET ME KNOW---IF THE ANSWER TOLD YOU something you did not know--rate the solution----

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.

32 isnt a valid code for your model. Mitsubishi model WS55859 has only 5 possible codes they are 12, 21, 22, 23, and 24 Double check the code again and resond to this same post and i will assist you.

It is usually a vertical deflection circuit problem. Here's the basic troubleshooting:

1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
2. Press MENU button. If a small horizontal line appears at the center of the screen, you have lost vertical sweep on your TV. The protection circuit shuts down the picture to protect the tubes from burning a line across them. The intermittent problem may indicate a loose solder. Try resoldering the vertical output IC. The IC along with the B+ feed resistor back in the sweep power supply is most probably bad or has a loose solder.
   
3. Press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
   
4. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "24", the LED will flash 2 times, pauses, then flashes 4 times. The error code is repeated a total of 5 times. Error 24 indicates a vertical deflection circuit failure.
   

Please let me know the code you'll and I'll tell you where the problem lies and how to fix it.

needs to reset tv. check for timer menu, and deletes all entry, and test again.
