Question about Samsung HCL4715W 47" Rear Projection Television
Hey, I am going to be replacing the horizontal output transistor but I am wondering if I could sub something else in. I am wondering if someone could tell me the base drive that the transistor has on it. I was looking at an IGBT that would work great if there is at least 10V of drive on the gate. If I could even get the schematic on that portion of the circuit that would be even better. Thanks
IGBTs do not work well at high frequencies. They are not very linear, either. Even if it works, you'll likely wind up with a compressed and distorted picture.
Just put in an equivalent output transistor and call it a day.
