Hello Folks,
I Have a Sony Projection screen television KP-57ws510 with a convergence problem. Back in February of 2013 the Convergence IC's took a dump and i replaced them with Oem Sonyo IC's and everything worked great until last week when the convergence went out again.
I opened the back of the television and noticed that one of the convergence chips and its heatsink was ice cold leading me to believe that one of the pico fuses dropped out.
