I bought the Famicom software "Door Door" which was sold at a discount because it didn't start. From the rule of thumb in the past, I was convinced that if I clean and polish the terminals anyway, it will start up.
Unfortunately, when I start it up, it doesn't respond even if I clean the terminals or polish it shiny. It was a completely broken defective product. The shop staff isn't lying. I'm bad because I didn't trust it.
However, if you repair it, you will have purchased a product that starts normally at a really low price. In order not to lose, we will identify the cause and try to disassemble and repair.
