Question about GE 46GW945 46" Rear Projection Television
And now my 46gw945 has a black bow in the top of the screen, and the colors are all screwy can anybody tell whats wrong???
The GE (actually RCA) 46GW945 uses the PTK195 chassis. There is a separate power supply for the convergence circuits in those sets. The earlier versions used a switching transistor but most sets use the STK730-010 power IC. I have seen many of those IC's stop working after a power surge, resulting in very curved sides with screwy colors. You can remove the back and you will see the 2 main boards at the bottom of the set. The convergence power supply board is mounted above the board on the right (when viewed from the back) and has a pretty large black IC mounted on a little heat sink, labeled STK730-010. Replace that IC and the colors should return to normal. If you do not have experience replacing IC's and working on TV's then allow a qualified tech to handle it for you.
