Hi sorry to bother once again... I have figured out that i pretty much need to replace IC`S in my KP-57ws500. People have mentioned that i should replace resistors, fuses, and maybe other things? So could you please give me the breakdown of what i should replace to fix a double vision, red arching line problem. I do have the part numbers for the IC but need some help figuring out what i should replace .Please HELP. Thanks

You will no doubt need two STK392-560 ICs and quite possibly two 3.5 amp pico fuses, and its a good idea to get two 4.7 ohm 1/2 watt resistors as well. You can get all the parts you need at the following link and they will provide free installation instructions with pictures and free online tech support while you do the actual repair if you need it. Heres the link.

Double picture out of alignment


Hi:
Your problem is its time to replace the convergence IC's. Replace both of them as if one has failed depending on which color is out of convergence the other is not far behind. They are the two large black IC's mounted on a large metal heatsink, also while replaceing them check the small yellow or green micro fuses underneath the IC's to make sure none of them have opened from the result of the IC failing.

There are red, blue and green lines going all the way across


it sounds like a convergence problem; in the customer menu there is an option to adjust it with the Sony remote---if either blue or red will not adjust in some direction---you have a bad IC---this set uses two STK-392-560 IC chips for convergence---both would need to be replaced and the set adjusted again. If this has been helpful give me a vote here---if you need more direct assistance--------- etower.766@netzero.net

The convergence IC chips are available on Ebay from Surburban Electronics for less then 14 dollars for the pair.(plus shipping)

Oh no it is less expensive to repair the printed circuit boards. You should buy only the IC,s that sony recomends you to buy. They will cost you more then a replacement IC will but they are not all alike even if they have the same numbers on them. Go to http://www.partstore.com and enter your model number and look for the STK IC. Don't forget to get some heatsink compound to install on the back of the new IC's before you reinstall them.. Remember to always double or triple check your work and make sure you have no solder bridges or shorts on the board. If you need a copy of the service manual, post your e-mail addy and I will send you one thru Pando. Pando is available online at www.pando.com for a free download. Pando lets you send large files via e-mail and the Sony manual is large. Good Luck
