I should also mention, with the LC Chassis, when the tuner was working, before it faded off to nothing, I saw a lot of weird garbage on the screen that is not there off the A/V I added in.
I would see Red, Green, and Blue dots, slightly off center, in an even row from top to bottom that would shake a little.
As well as to the far left of the screen on a darker image, I would see a faint vertical bar, in red, green and blue. Both would change and go away if the fine tune was adjusted for a less clear, still color picture.
Generally, the tuner produces nothing unless the AGC is turned very far clock wise. No static, no sound, just a blank screen.
