Let's look inside an industrial VHS VCR from the Early 80s. Panasonic AG-6800. It has HiFi Sound and has a parallel remote connector for remote control and to use this as an edit feeder VCR.
Let's replace the broken panel on the Samsung 55" Q7 TV with a new one.
Hopefully not breaking it in the process. It is a big and delicate TV Panel.
At the end a big peel off the screen protective sheet.
I setup Windows 98 on a Pentium 3 Computer and try out a few things.
I had to blank parts of the screen to avoid Copyright issue.

Some fault finding was required for this. The service manual is very helpful.
