How to get these buttons working

[unknown]

My projector screen only works via the RF remote how would I check the way the wiring shold be to the plug so I can resolder?

Have you disconnected the switch panel? Can you post a photo of the main PCB from the top.

Thanks for your reply Do you mean tried the remote with the switch disconnected? Or just disconnect it because I have had it disconnected before.

What do you need to re-solder?

I want the buttons to work on the switch. At this point only the remote works.

I still don't understand, maybe it's me.

What do you need to resolder?
Which plug are you referring to?
What is at the end of the cable that is connected to the switch panel?
Has it ever worked?
