I did run back through the pics link Hull Chipper posted for us. I did not see anything in those pics that stood out as the voltage regulator but I know it does either have one or something simular somewhere. Those pics are informatived but
not detailed enough to identify what might have caused your problem. Sony could have built it into the power supply for all we know at this point. I'm sure once members gradually start getting theirs here, we will start learning alot more. Hehehehe
This might just be our first mod to be performed.
