today I talked with a retroshopper of my region and this guy tell me that my problem with the saturn is caused by too much time without playing with it and affects the pal version expecially It's sort of correct. The common model 2 VA9 boards have these issues. The less often you play with them the longer they need to "warm up" and work without crashing/freezing. I suspect the problem is caused by a combination of using the old PLL chip and a different layout of capacitors compared to Model 1 machines, which makes it more susceptible to capacitors not performing up to spec - which they won't, due to old age. However I found that replacing the caps will make this much less of a problem. Note that capacitors have a finite age of ~20 years, the electrolyte in them dries up, and they won't perform as well. So you need to recap old hardware either way, not just due to bad/leaking caps. Japanese units don't use that layout + PLL chip combination, except for a few model 2 V-Saturns and all model 2 Hi-Saturns. Normally they use a newer PLL chip which is more robust, so they aren't affected that much. Well, if I understood it seems that the better saturn's version is the japan one (maybe model 2?) but I have to bring my consolle to repair in any case.

The JP models can get bad too, and all units need the electrolytic capacitors replaced as they are on the end of their life cycles.
With proper maintenance, all the units are equally good, PAL, NTSC, JP, whatever.
Except the yellowed Japanese units. Can't do anything long term about those, even the hydrogen peroxide bath is only a temporary fix.

Hi, it's a long time that I don't write here. I have a great new for my saturn's thread here! Finally I had a chance for fix the problem by a professional technical in a shop of my country! In other word the problem wasn't in the capacitors but in...... THE OPTICAL GROUP! It was just a replace work!
