Why some buttons do not react

Hi @cambo

It may be that the contact surfaces of the buttons/ circuit board in the remote control has either been worn away with use (usually happens with the most “popular” buttons) or hopefully they may just be dirty and cleaning them will solve the problem.

Here’s a link to a video that in general show how to clean the button contacts etc in a remote control.

If cleaning the buttons doesn’t resolve the problem then perhaps you may need to replace the remote.

If you decide to do this then here’s a link to just one supplier.

It is not a recommendation to use them. It is shown just to give an idea of the cost of the replacement remote. There are other suppliers online that may suit you better. Just search for Sony RM -S316 remote to get results.
