Uhm, seems like the dreaded black screen syndrome specially from v10's. Check 3 resistor banks placed near the IOP(on the same sid as GS and EE). A black screen means usually one of those banks is ruined. Test them this way: if you test resistance from one side to the other they will give around 43-47ohms, the secret is in the side by side measurement, since its a resistor bank, resistance side by sid should be high, if one of them gives low resistance then the bank is ruined and you need to replace it.
Search one of my posts on how to measure the resistance on this banks.
