Don't have the model number handy, but the set was made by Sanyo and sold by Fisher, dated 1996. It wouldn't tune in any channels, the voltages (5 and
9VDC) were present on the tuner and injecting a signal into the IF stage produced a normal picture. I had every reason to suspect a bad tuner, but once replaced (with a rebuilt one) I got the exact same result. Apart from checking the supply voltages, and injecting an IF signal past the tuner, I don't know how to troubleshoot it any further. I checked around for bad capacitors but couldn't find any. Is it possible the replacement tuner was bad too? Or is there something I'm missing? Thanks for any advice.- posted
