Kp-46wt500
With set off and using the original Sony remote:
Display, 5, vol up, power
Buttons on the remote will let you cycle thru the menu to the convergence adjustment--do you know what buttons to use and what they do?

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
Solution #1
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

It depends on whether you can do the repair yourself---it sounds like you have a bad convergence ic--this model uses two STK-392-560 convergence chips(You can buy both on Ebay for less than 15 dollars plus shipping.)
Most of the time just the two chips need to be replaced and the set adjusted with the remote.
Many shops will charge 300 or more for this kind of repair---This repair should be able to be done in your home---I have done hundreds of them---shop around and see if you can find someone who will do it in your home--if they say it has to go to shop keep looking. I do this kind of repair here for 200-250 depending on the set--I doubt you could replace this set for 200 but it is a economic decision.

Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

You can download the manual for this at:

and there are other sites as well---it should explain among other things all the controls used when in tech menu for adjustment and to save the adjustments.
