If the D board didnt correct the convergence issue the problem has got to be the wave generator on the A board or possibly the Velocity boards themselves that are bad.

Boe in blue dynamic convergence curcuitry. Swapped deflection yoke on two tubes but problem still remains. Unplugged convergence plug on yoke and bow disappeared but unable to adjust dynamic convergence....


what's the number of the board where you unplugged the conv yoke, should start with 930_ that is the board you need. Try the partstore.com with the part number or type in the brand and model when you have the number on the board, and they display price and availability.

Menu screen appears constantly, volume decreases by itself


Hi, common issue with rca sets, you need to replace the tact switches on the front control board. If your not good at soldering / un-soldering you may be able to still purchase the whole control board, call a local tv shop with the complete model # and chassis # of your set and they can give you price & availability, video-tek

Hitachi 43F300 convergence


Hello,
Do not replace whole convergence board.Because convergence data stored in old board cannot transfered to your new board.Means in your new board there is no convergence data.Unless you have the service manual and know how to get service menu.

I believe if you have convergence problem one of your IC (STK) is bad along with couple of small
Value resistance.

Dont forgat to Rate!

Good Luck

Conv problems with no pic has sound


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 projeciton 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 photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Toshiba tos-50h81 convergence issue


you have this in your menu. but your menu will not adjust and fix your problem. if all three colors are bowed in at top and bottom...red green and blue... then you need to change all convergance ic's and check fuses. also there might be some solder in fuses hiding on the board. Need to also check all fuses around conv ic's and around conv yoke plugs.
good luck.

Sony KP-51HW40 Convergence issue


First if the auto convergence isnt working you need new Ics . two of them.I am part owner of a site that sells the ICs and provide free tech support by way of online instant messaging and we include detailed instructions on how to do the repair yourself. We also have a service where you can send your board to us and we will install new ICs and all new Convergence resistors and ship the board back to you. Or we sell remanufactured boards. I would recomend replacing the two ICs as that would be the cheapest rout the ICs arent exspensive , but will require de-soldering and soldering in the new ones. Here is alink to the site. You can go and send them a request for information by clicking on the contact us link in the lower left info box. Someone will get back with you quickly just leave your model number and what you would like info on.

Sony KP-51HW40 Convergence issue


Can you adjust the convergence by the convergence menu without going through the service menu? The settings through the convergence menu should save automatically. Have you replaced the convergence ICs? If so the settings should save, if not the D board will need to be replaced or at the very least rebuilt. Let me know if you need further assistance with this issue.

Samsung HCN4226W Service Menu?? For convergence issue????


The resistors on the new module are not 100% Identical in resistance to the originals on your board, to access the svc menu you will want a service manual and will require some patience. It can be tricky I would personally call a repairman with convergence in mind. Or order a manual and read the conv section several times. http://www.eserviceinfo.com/index.php?what=search2 Is one site, might have to purchase one.
