Sound went out a few days ago, tried using a sound bar but still nothing. Was thinking something must be wrong with the main board. Any ideas?

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!

Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input). After extracting the main board from the shield, I replaced 7 Capacitors...04-30-2024, 08:20 PM -

I´ve been given an old CRT from Panasonic, it´s almost new, it was storaged and almost not used since bought.
It is imaculate inside, almost no dust or debris inside.

So I started to look for a service manual, I found one, and started from the beginning.
Most of the times the caps are the problem so I orderer all the caps for all boards,... -
Got a bunch of Motorola Minitor V pagers from Fire Departments here trying to fix some out of the non working ones. These pagers are known for either no sound / audio or they don’t charge. The internet is full of suggestions like metal shavings inside the speaker?
Anyway so I took one of the Minitor’s apart for my amusement in order to see why that is and nobody can fix em.
There are no service manuals or schematics for these that I know of. However… I did find the problem!
On the main board of this unit where the speaker connects to there is a metal shield....
