This is a 37" phillips plasma 37fd9954/17s with the common power supply problems. It has an mc34067p ic. These fail along with the caps near the heat sink. Has anyone run into this and are schematics anywhere to be found? I did find a data sheet on the ic and plan on starting from there. I am looking for a little more info on this power supply. The front half seems to be working fine running around 330vdc, but I can`t get much out of the second half. I think the ic is shutting it down or not letting it start up. Thanks, Cadiman
