SOURCE: i have the mitsubishi 55711,i have a double image

This is a V-21 Chassis common, with these symptoms, for failure of the convergence amps. This set uses two STK 392-110 Sanyo amps mounted on a heat sink and hard to miss. They're a 40 pin ic about the size of a half pack of cigarettes.
It has also been my experience that two or more of the yoke return resistors need to be replaced, most commonly R8c21 and R8c22, both are 3.9 ohm 1w but test all of them for reliability.
Hope this helps!

SOURCE: Convergence Problem

Unfortunately you will have to replace the convergence board in this unit. it has failed. this particular board regulates the alignment procedure that you are having issues with. replacing this board will fix this issue.

SOURCE: tv screen colors are separating. cannot align

What you might be experiencing based on your symptom sounds like a damaged convergence IC.

If you cannot move the colors with the convergence menu then you have a damaged convergence IC.

With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00.

If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

I have attached some photos of really bad convergence problems, your picture may not be exactly as bad as these, but here is something to compare your set with.

Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

I have a magnavox 32MF301B. How do I connect a wii to it? I've tried matching colors of cords and it didn't work.


Don't connect colors. The white and red cords should go in the "audio" outlets in your tv, and the orange/yellow cord should go in the "video" outlet in your TV.

I got a wii and tried to hook it up to my toshiba tv and when i turned on my wii it was black and white and im positive i have it set up correct or if its just the cords itself the colors are blue green...


Make sure the plugs EXACTLY match the jacks on the TV. If you plug just the green cord into the TVs yellow jack, you will get black and white. If your tv has a combo jack (uses the green of a component input, make sure that the tv is on the right input (COMPONENT and not VIDEO).

let me know.

My screen showes triple image with green and red siloettes like it should be 3D but it is not this just came on overnight What might be my problem


ll projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Bought new componant cables for new tv and the wii will not play in color. tryed moving cables around still no luck the different combo's that i tried either switched every thing to all red or all blue!...


Make sure the colors line up.
Red-Red
Green-Green
Blue-blue

If the tv has a second componant input then test it in that input.

Whats causing horizontal lines in my philips 42 in. plasma tv? seems to be 4 sets of lines with about 15 to 20 lines in each set. Also has the red vertical explosion from images on the channel im watching.


There are very fragile ribbons that are attatched to the top of some LCD displays, if these have been pinched or damaged in anyway, this can create what you are describing. Was the LCD panel ever hit by like a wii remote around the tv bezel or did it fall without cracking the screen? It could be something simpler like, some really wrong color settings or something...

3 red lights is the red ring of death, 4 means your AV cable is disconnected. If it freezes up though, you have a bad DVD player in it. I would send it back.
