This TV is a few firsts for me: first KD-series (digital) Trinitron, and the first I've worked on from this era that doesn't do ANYTHING when plugged in. Neither the front panel button nor the remote control activates the set. I don't even get any standby LED blinks!
Nothing looks compromised on the mainboard. The TV makes no noises at all...just as if it was never plugged in. I don't even know where to start on this one, oh dear. Thanks again you guys, for putting up with my constant service requests.
