I have a marshall vs65(valvestate) that when turned ON lights up for about A second then turns OFF. initial fuse to the power switch is good. If anyone has experienced this before and knows whats going on pls let me know cause Im stuck.

Well from looking at the schematic it's more than likely something shorted in the power amp section. Not sure if these amps have a thermal circuit breaker on the power amp heat sink, but if it does and something's getting hot, the thermal breaker will shut the amp off until it cools down. Best to have a tech look at it and see what's up.
