The STK's are probably blown again. You need to pay close attention to the resistors around the STK's. If you have ANY bad ones you have most likely reblown those chips. Let me know if this helps.

Replaced Convergence chips, same problem


This set has pico fuses on convergence board and also on G power board, there should be 2 5 amp pico fuses on power board.

If convergence is bad exactly as before double check the power board fuses and check to see if voltage (it is marked!) is there with power board disconnected from chassis..

I have a Sony KP-53HS10 TV for over 9 years. It still works great, good picture. But few weeks ago, it started making a "ssssssi" noise after turning on 4~5 minutes. The noise might come from a cooling fan...


There are no fan in this tv.This tv most common problems are the dead convergence board parts have problems,picture have colors lines R,B,G out of alignment,have colors shadows,and 3D pictures.The convergence board must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved convergence problems.The problems u discribing,it a starting point,just the convergence problems,have not take it effect yet.Sooner or later ur tv will have the convergence problems.

SONY KV-32S25 TV SHUT OFF...NO POWER NO SOUND


You have a blown fuse. It should be a GMA7 amp or a 5 amp. You could try to replace it and see if your TV works again. If it blows the fuse again, then there is something shorted causing the fuse to blow. Then call a good TV Tech.

You also need to check following pico fuse PS8001 to PS8006 (6 fuses) as few can be blown off and requires replacement.

You should do above said repair if you have knowledge of electronics, have experience of big TV repair, have necessary tools and know that electric shock risk is involve in TV repair.

When one or all the colors are bending severly, then the convergence circuit is not functioning correctly and must be repaired. Only one color bending means just the convergence ICs and all colors bending means convergence ICs and voltage supplies. Convergence issues are the most common problem with rear projection (w/picture tubes) televisions. The cure is replacing the convergence IC's. Sometimes the pico fuses need replaced as well. If you have the experience to use a soldering iron and a basic understanding of electronics, then, you may be able to do this job. If not then call a servicer in your area. Go to the Sony website, Sony.com, and you can locate one in your area.
