Power issue (?) on a Sony VO9600 u-matic
Hi all,
I wonder if anyone has seen this issue before. I have 2 of these machines - one works great - the other has a power issue. The symptom is: - on power on (switch at the front), the VU meters twitch, the front lights (SP/High band etc) flick on for a split second and then the unit goes dead. Buttons don't respond, no lights on - nothing. - occasionally - usually after being left switched off for 5 mins or so - the unit DOES power-up successfully and stay on. If you power off and on-again, it goes back to the fault So far, I have swapped over the AC-DC and DC-DC power boards (which are known to work okay on the good machine) and no-change! Before I go any further, anyone seen this before? Given its not the power supply itself, is this some sort of safety shutdown/short-protection from elsewhere? Couldn't see this noted as a common fault so was hoping someone might have some pointers. Rob |

I had the mains power switch go intermittent on one of mine.

Thanks wave solder !
You were 100% on the money with my machine. "Servisol"-ed the front power switch and problem solved. Fitted a replacement pinch roller (thanks whiskers), cleaned, oiled and greased and works a treat! Thanks again Rob |
