Sony KP-41T25 convergence Can't Post
I replaced the STK392-010 with -040"s seem to have straightened out red and blue , but green is twisted like a bow tie. I re soldered still the same. On the convergence board I can plug the the red or blue into green and have bow tie effect on either. One more thing, I have never done this before, guided by web forums only. A lot of the forums referred to several Pico fuses that will need to be replaced in conjunction with STK"s, I didn't find any. Looking at the service manual it appears to me the only fuses are the glass variety. Resistor look good, capacitor are not swelling , I don't know what to try next. Thor

have you double checked the soldering to make sure there is no minuscule blob short circuiting two pins?.use a magnifying glass

Used a photo loop to check joints, looked good. I removed the heat sink connected to the blue, green STK, underneath were a series of resistors, four of which were darker then the rest and the circuit board underneath was darkened. I believe I followed the green output to these resistors, so I am taking a chance and replacing them. Sony #1-214-673-00 4.7ohm 1/4Watt 1% tolerance. The resistors were at 4.8ohm when I put them on the meter. &lt;br&gt; <br>Well I got the resistors that is not it.
