Question about Denon AVR-1200 Receiver
My AVR 1200 went into Protection mode after being hit by a 440 V surge. I have been told that all ICs in the Power circuit have been blown off and resistance values have increased. I have seen that several capacitors have been blown off. It's possible that other sections have been damaged too. But I was told that can only be ascertained after setting the power section right. My mechanic's opinion was that even if things are set right the perfomance can't be guaranteed.
What would be the experts' take on this - would it make sense attempt repairing the set.
Something in the circuits got fried, most likely it blew out the entire board. ALL OF IT.

Electronics like a receiver are so sensitive to power surges. I'm sorry to say that it's most likely unrecoverable, especially if it wasn't plugged in to a surge protector. Even if it was, they don't all protect 100% from surges. :-/

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

Do you still have the AVR1500? I have one with a bad tuner--and would be interested in purchasing your for parts. Let me know if you still have it and if you'd be willing to sell it.
