Greetings!

To provide you with the correct parts, we need to know what the model number of your set is. BUT, firstly, you made not need to replace parts. Many times when the problem with convergence is intermittent such as yours, the problem is poor solder connections on the STK voltage amplifiers, not the parts being bad. That's the first thing to check.

Hope this helps

How do you fix convergence on a sony tv?


hello!
If convergence in your TV went out suddenly and severely, there is nothing you can "adjust". That's a parts failure, convergence amplifiers I.C. chip(s) went south. Needs repair! Period! Minor alignments could be done by applying "flash focus" or "manual convergence" off "menu", if available.Some models have "flash" only option. Anyway, make sure there is no large metal structures near the front of TV or large speakers nearby. that could convergence to go out. Try not to play with any adjustments, if severe convergence problem. you won't be able to fix it right and will corrupt memory settings for "flash" option.
thanks,
Alex.

(5) Stretched Image at top and bottom edge very distorted. Reheat all the surface mount solder points on the Small Signal Board. Then realign the set including convergence menu. To enter service mode: power off the set for 10 sec, then hold down Vol- and Ch- buttons for 10 sec. See this link: Alignment Procedure (pdf)


Also download the Alignment procedure pdf file. Hope this will help you. Please let me know if the information was of any help to you or you need further assistance.

Good morning, I am in the moving business and have a customer that wants me to move their large TV Mitsubishi medallion tv. She thinks is comes apart in two peices for easy moving and I need instructions...


If the model is a WS-65809 that sey doesnt come apart. Actually very few rear projection TVs can be seperated Some RCA TVs can be disassembled to several pieces. Also I would let customer know that because a CRT TV has three CRTs that are aligned to each other , Moving the TV will cause the convergence to be adjusted. Based on model it can be just pressing the auto convergence option with the remote, But older rear projection TVs (2003 and older) have been known to blow ICs after a move when trying to reset the convergence. The ICs weaken over age and they can blow anytime the convergence adjustment feature is used, so its always a good thing to let someone know that even if very careful when being moved there set may develop convergence issues after a move because its a 3 CRT rear projection TV

All 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.

take the original remote and in the customer menu look for convergence--does the set adjust in all areas in the convergence mode? If not you have bad convergence IC's--a model number would tell me a lot.

Red horizonal convergence tilts instead of adjusting evenly.


For your hitachi unit one of the convergence IC is bad along with couple of low value resistance on
the convrgence board.

Good luck

51mp392h Blue Convergence Problem


Hello rogeuryder,

This is the one thing that even make TV repair persons shudder. You don't really have a convergence problem in the normal sense. The convergence works. What you have is a misaligned convergence situation which any documentation and or book on TV repair will tell you that at this point manual convergence adjustment is needed and the only thing you will have to do is keep trying to adjust the convergence until you get the center aligned, and then work towards the outer edges using both static (Center) and dynamic (outer edges) convergence techniques.

As this may sound it is; Very Very Tedious.

Here is something that may help you:

http://books.google.com/books?id=ttBofTJM7FEC&pg=PA112&lpg=PA112&dq=static+convergence&source=web&ots=hyUMeeY9s6&sig=DZm27q1aMbLiwKA__fyysBd2yUE&hl=en&sa=X&oi=book_result&resnum=9&ct=result#PPA112,M1

I have used this book when I use to teach TV repair. I hope you discover what I am tried to convey in my e-mail, this is no longer a question of can you fix a TV? It has become a question of do you have the patience to adjust a TV.

Good fortune in doing this, you will succeed if you just take your time and do static convergence first and then do the dynamic convergence with the manual controls. The procedure will be in the service manual.

I hope this helps

Thank you,
