Title: Super Mario Bros no sound.
Post by: Viper155 on August 12, 2016, 11:42:35 am
I just bought a super Mario Bros that has no sound at all.  I've checked the volume control but that doesn't change anything.  The guy I bought it from said that he was playing it one day and then he heard a loud pop and it hasn't had any sound since.  Any suggestions on where the problem may be?

You may try looking at the pcb, check for bad caps/pot

Fixed!  It was the sound amplifier.
