Solved! My TV cannot change input source

Oct 21, 2018
I recently got a second hand Samsung SyncMaster 933HD. It's a relatively old DTV/PC monitor.

It has 2 HDMI ports so running a Playstation should be no problem. My problem is the buttons on the side of the monitor don't work so I can't change the source to hdmi. It is stuck in PC mode. I've also tried using Peel Remote but it doesn't work. Is there any way I can change the source to hdmi? Or am I doomed?
