Monitor lives its own life ;) Turnes off and on in random moments

Sorry no magic wand exists, but you don't have to insult me by declaring that I was "saying nothing".

I work on these all the time. It simply needs to be repaired.

No mere words will actually help. The only thing that will help is when someone repairs it.

If you can't do it, I urge you to take it to a shop. Sorry no magic wand exists, but you don't have to insult me by declaring that I was "saying nothing". I work on these all the time.

Okay. As I say, I work on these all the time. I actually refurbish them.

For good measure, I replace all four of the output transistors with TIP41Cs because they handle the power much better and don't get so hot.

It requries a little cutting on one the metal shield so the tabs of two of the transistors won't short. That will be obvious.

The output transistors are the little tabbed ones between the output transformers.

I also replace all the polarized electrolytic capacitors on the main board, even though only one or two may be bad, because the batches they use seem to all go bad sooner or later.

I use good quality caps rated at 105C.

I then resolder quite a few connections in the power and inverter sections to prevent future trouble.

Now if you just want to get your current problem fixed so it will work until one of the other above components or connections fails, I would suggest that you look for bulging or leaking caps in the power supply section.

The first suspects would be the caps located by the group of three heat sinks - that's roughly the area between where the video board plugs in and the main large power supply capacitor is.

That's as specific as I can get. Good luck. Okay. As I say, I work on these all the time. I actually refurbish them.
