Unique AV Electronics@Akshit2111 : where is the Marantz service center? Can you PM me the details..
Hdmi section of many brands are reallyI generally dont have any fluctuation in my area. Basically in my tv cabinet all the speaker wires( 4 atmos and 2 surround 3lcr) assemble in a tight space where i am supposed to keep my avr so some of the wires got squished by my avr as the space is quite tight. I am afraid this could be one of the reason. I have never had any such sudden power surge problem in my area.
29000 for hdmi board change. Apparently it has to be imported and the availability is scarce.What's the status of your AVR ?
