Working Atari 1040STF/SC1224 Suddenly Lost Picture

[tjlazer]

Welp I seem to have lost another monitor tonight.  A newer Goldstar SC1224. (No badge, printed label on front.  Mar 1989) Same tune.  Pulled it out of storage a few weeks ago, had it setup and working great.  Been using it every day and the last week it would lose power and turn off on it's own.  Turning it off then back on would resolve it.  Did that again tonight and this time it won't stay on.  No loud noises or anything.  It just won't stay on.  Green LED comes on for a second then goes off.  Would that be a bad PS in the monitor?

 

EDIT:  Let it cool off for a while and it's not working again!  What could the issue be?

It may be simpler to get a SCART cable and a SCART->HDMI adapter.

tjlazer: it is really not possible to even remotely know exact cause/component what causing this failure.

It is job for some service man - like TV repair man. Yeah, they may be rare birds now. Cost may be too high now. But if you have no experience with fixing electronic, better even don't think that can fix it self. Minimum is to have some soldering iron, instrument for measuring voltages, resistance, components . And to know basic electronic, components.

 

Just this - it may be that some component/section pulls too much current - like high voltage transformer with broken insulation. PSU starts, and switches off because of overload.

Personally, I would not bother, even if I'm who can fix it - if can find replacement component. Too old, will broke again, soon . Ah, and LCD consumes less power 🙂
