Hey guys. I have a vht 2502 that won't make any sound when taken out of standby. Cables are good. The A channel had been acting weird for a while so I've just been using Ch B. Now B is gone too. The fuses, main and the front fast blows, all seen ok. Yesterday when playing through Ch B i noticed that my toddler son had taken ch A out of standby with no load. He loves all buttons and switches. It'd been a couple minutes before i noticed and threw it in standby. That's everything i can think of. Any thoughts ?
