    does sanyo and sony interchange because the part numbers and site is for sanyo my tv is a sony KP-46WT510

  • Tanya LeVasseur Aug 16, 2007

    I got my ic's they said nothing but the stk #392-560 even though I ordered them as sanyo..Do you by chance know the original part # for sony ic's for the color convergence.
    Shortness

  • Tanya LeVasseur Aug 17, 2007

    Thanks again techman I did go back into the sight and went off. It would have been worse if I had to end up paying to have them replaced in a few months..We will see if they live up to any of it ....I really don't see it happening but hopefully noone else will end up a victim to this nonsense...

  • Tanya LeVasseur Aug 17, 2007

    just one last note. Something good did come out of my search for everything. If anyone one needs an original remote there is mr.remote on ebay you can buy from store instead of bidding they are the most reasonable I found mine for around 23.99 with free shipping real good service. NEW remotes everyone else wanted from 50 to 71 dollars with shipping. Good luck all

  • Tanya LeVasseur Aug 18, 2007

    Sorry all. The remote store is awesome remotes not mr.remote. It has been a draining day. Sorry again

The system will not let me post to a link, I wrote: OK first off, as you stated, you will for sure need an original replacement remote for this TV set to make any types of alignments. You may also have a friend relative or maybe a neighbor who may have a remote you could borrow. If not, there is one available here http://www.remotes.com/remotes/servlet/rs?a=gmi&smodel=KP46WT510&brand_pn=SONY_KP46WT510&mode=large&uid=11859736726080 Now the convergence IC's, there are two of them that will need to be replaced, the number is STK392-560 You can get the original Sanyo IC's from HERE http://www.mcminone.com/search.asp?keyword=STK392-560&btnSubmit.x=10&btnSubmit.y=8 You will also need to get some heat sink compound and apply to the backs of the new IC's before you install them. Now after all is said and done, before you plug in the set, take a multimeter and check resistors R 8122,and resistor R8127. These two resistors supply the voltage to the IC's. They are 7.5 ohm resistors. The R8122 carries the negative 22 volts and the R8127 brings the positive voltage to the IC's. Next, check the circuit protectors around the IC's also. They are PS8001,8002,8003,8004,8005 and PS8006 and make sure these are not open. These circuit protectors are nothing more then 3.2 amp fuses. I do not have the KP46WT510 service manual, so you will have to go to servicemanuals.net Good Luck

    The convergence IC parts used in the Sony is made by Sanyo. There are replacement type STK iC's but like I said these are aftermarket IC's You need the IC's that have Sanyo on them. You will be on the same river without a paddle several months down the road.

  • Larry  Dillon
    Larry Dillon Aug 16, 2007

    If you purchased them from MCM, they are getting as bad as the other parts houses and ripping off the public. Their web site says they are the original Sanyo IC's. But without Sanyo on them, they are cheap after market types of IC's. Go back and tell them they are using false advertising.

  • Larry  Dillon
    Larry Dillon Aug 16, 2007

    i guess if that is all you can get, use them, but just be sure to use a lot of heat sink compound on the backs of the new IC's before installing them.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

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.

SPEED BUMP OR BOWING


Your convergence chips and convergence resistors are going bad. When they fail the screen colors will look distorted/3d looking. Another symptom is one or more colors can't be converged using the convergence menu. You can purchase the parts over the internet. Just make sure you get Sanyo brand convergence chips and the correct flame proof resistors. You can also check the site www.TvRepairKits.com for a kits.  Just make sure you replace both of the convergence chips and all of the convergence resistors.

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
