WG 19K7601 random turn-off

[snipa]

I've just got my Xbox running in my cab on my K7601 monitor, and after sorting out the 50/60Hz problems, it was running fine despite still needing a few colour and positional tweaks when the probkem arose.

Anyway, it's happened twice now - after playing for a short while (10-15 mins) the screen just decides to turn itself off. I didn't have to leave it longer than 10 mins before it was works again, but it's just not acceptable.
I've no idea what the problem is, but I'm using one of Ultimarc's new XBA adaptors, which I'm sure isn't the root cause of the problem.

I know it will be the first question asked, and 'no' I've yet to install a cap kit, but is this the likely solution or is there another potential problem lurking?
When the machine was a dedicated JAMMA, only a few weeks ago, it ran really well with a sharp picture and some of the caps can be seen which have been replaced.

Obviously, I'll change all the caps with a K700 kit, but is there any others I should do at the same time, and will this solve everything?

Thanks for any help guys!

The K7000 capkit is needed right now. That's generally what is causing the problem is bad caps, but also numerous bad solder joints (especially around resistor R89).
