I'm wondering, Can my MZ700 go up in smoke twice? The first time happened over 1 year ago. I was keeping it on, with no CRT connected and then it just started going up. Smoke appearing out of the speaker. I quickly turned it off and it still smells like it. So I am scared to turn it on.

Open it and take shots and post them here if you cannot determine what the culprit is:
1) the motherboard.
2) the inners of PSU.

@hlide, Once my dad opened it up and gave it a clean it didn't happen again. I think it was the PSU because the motherboard looked fine.

It is certainly the filtering capacitor input power supply box.
I changed it in February but even without it, the system continued to work.
