Bad, Noisy, buzzy sound
Today I plugged my old sega genesis (I'm writing from Portugal, here we call it mega-drive), didn't use for at least 10 years. The last time I used it, it was good, I'm almost shure didn't have any problem.
Today, I plugged it and I notice the image was bad, but the worst part was the sound. I'm gonna try to describe the best I can, with my bad english, the sound was buzzy, noisy... I thought it could be a problem with the tv, or the cable, so I plugged my headphones to the genesis, and it was the same. I'm sure the problem is with the console.
I've read it could be the voltage regulator, is there any way to test them? DO you have any idea of what could be?
