Question about Marantz SR-7200 Receiver
When I turned on my marantz sr 4200 , for 4-5 minutes , it has peaks, the led indicator is red , and I hear a lot of noise in my speakers .After this period it work normaly , and peaks disapered
This is an indication of some bad solder connections on one of the boards. It could be the power supply board, amp board, or the digital board. I would like to be more specific, but this is not a common problem with those symptoms. Bad solder connection are a common problem and can cause many different unusual symptoms. Unless you have excellent soldering skills, it would be best to let a service center repair this for you. This is a very good receiver and is well worth getting fixed. If you have excellent soldering skills and are willing to take a chance on fixing it yourself you could save yourself some money, but be aware that if you make even one mistake while soldering, you could easily cause much more damage than you started with. Some of the components that may need to be resoldered are surface mounted IC's that are very difficult to resolder and if you have never done this before it is not a good idea to start learning how to solder on such a nice receiver.
Let me know if you need any further help.
