I've recently replaced the convergence IC's on a Sony KP-65WV700 as well as a resistor that was shorted. I am now able to achieve proper convergence per the service manual instructions, or via the user menu; however, upon saving those settings and turning the TV off, the convergence begins to drift , usually to the left. It seems to be through the entire screen, but can show a greater drift in certain areas, with no discernable patterns. Each time this happens, I try to re-accomplish convergence and ensure to exit the user menu or service menu properly after writing the values to memory per the service manual, with no success. I'm stumped as of this point and would greatly appreciate some help to get this TV working properly again.
Thanks,
Chad
Check all of your solder connections,make sure there not bridged and use acetone to remove any residue left behind from the soldering process.
