Question about Audio Players & Recorders
I have a DENON AVR-1500. It worked great until I got a static relayed shock when pushed the power switch. Now after the initialization process, "PROTECT" comes up on the display. The manual states that the speakers are short circuited or the ventilation holes are blocked. I checked both and this is not the cause. Any Ideas?
all i can do from your description, is to give you some of my views. so, don't vote me anything, except "faxya".
as you described, the speakers are ok, and ventilation holes have no problem, then, the problem lies with the Denon itself. the static may have hurted the "protection logic". do you know how to change its logic IC or to ru-burn the MCU(micro computer unit) and you do not have the unconteminated logic program anyway? i guess not. Not even the agent's servicemen can. It has been a long time servicemen are spoiled or hands tied up by the VLSI(very large size integration), so they just find out which PCB is in question and change the whole PCB, just like car service centers do. very costly to our wallet and to the environment!
