Sony KP-57ws500 rear projection television.

I was trying to replace the convergence IC's and cracked the D board. Does anyone know how I can fix the D board or where I might be able to buy a new one? And would you know the estimated cost if I have to buy one?

Sony KP57WV700 Convergence problem


Problem could be low voltage from power supply as well as the amp ic for the convergence board. Need to take voltage readings from the test points on the board and compare them to the readings you should be getting from the service manual.

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
