hi fella's has anyone repaired one of these samsungs it's a ps42b430p when to the customers house, he already took the back off, the fault it's clicking, i disconnected the xmain first still clicking, reconnected the xmain, disconnected the y main, still clicking, so disconnected both boards, no clicking now i get a slow flashing green light on the logic board the va/vs are the right volts 55/ 205, the lady said she plugged something in the usb then she heard a pop tv went off clicking strange one, could the mainboard have blown, thanks for your time
