Question about Mitsubishi WT-46809 46" Rear Projection Television
The vertical deflection IC if defective will cause the protection circut not to let the tv power up ,it has a thermal protection circut as well
here is the vertical deflection IC # la78045
and here is a link for the NTE equivalent part and specifications and pin layout
http://www.nteinc.com/specs/7200to7299/pdf/nte7209.pdf WARNING if you heat up any component to long or with to hot of an iron you can dammage the component and or the thermal protection circut
but I believe you will also have to replace the flyback (high voltage transformer ) with wire giving to much voltage
