Hi all,
I'm in the process of restoring a monitor ii that I purchased not working. Upto now I have recapped the main board and the unit now powers on. The rear controls and contrast knobs are now functioning since the recap however it doesn't want to display an image. At best I have a slight outline of the Raspberry Pi boot logo however the image is very distorted and wavy. Looking at the circuit diagram of the monitor would I be right in thinking it is possibly the transistors that are on the video in - Q101 and Q102?
My main electronics experience is with audio amplifiers and such. I have discharged the CRT and understand the risks assosciated with the high voltage.
Many thanks.
