TI Color Monitor problem. Looking for schematics.

Realizing this is an old post, but I was able to dig up two models manufactured by them between 1980-83, a 14" and 19" complete with troubleshooting and schematics/parts listings.

I know it's a shot in the dark, but I'm hoping with technology as it was back then even if the first isn't your model, there should be good similarity since same manufacturer? ¯\_(ツ)_/¯

 

To widen the topic some, here's the resource that may help out somebody else with other monitors: https://www.mikesarcade.com/arcade/monitors.html

Don't have the schematics... been a while since I worked on that particular issue... if you are at all familiar with T.V. sections... Following the wires from the deflection yoke coils to their destinations can often be enough to locate the Vert. deflection section.... usually two transistors with heat sinks, driven by an I.C.. I'd probably start by checking the electrolytic capacitors near the I.C., replacing with tantalums as I go... also sometimes there is a v.lin. adjustment pot. or fixed resistor.

 

    P.S. Sorry, if I'm being presumptuous.

Not sure I'd use tantalums since they are not supposed to be good with ripple.
