WG V1001 Horizontal line only
All my monitor is producing is a thin horizontal line on a black background. I have gone over every piece of the vertical output circuit, as well as the video driver transistor, video output transistor, and a handful of other caps, diodes, and resistors. A cap kit was done from day one so all the electrolytics have been replaced, and gone over with an ESR meter to be doubly sure they're ok. I had gotten a secondhand chassis to use for parts, if needed, and I swapped the circuit boards to see if there would be a difference...to which there is not. Same line on screen. My question is: Aside from the big filter capacitor (and 4 in 1 can), ceramic resistors, and the assorted diodes I have already checked on the metal chassis base, is their something on that base that could be causing the issue? Two different circuit boards tried on the same base, resulting in the same monitor symptom. The second chassis base is too far gone to swap out. Anyone have a suggestion?
