[Coco] Tandy Assembly Repairs

Hi.   Ian M helped me diagnose that my 4p has a bad power supply (blown cap). He is helping me out with a replacement

My only other hardware issue is a faulty keyboard on my ‎TRS80 Model PT210 Data Terminal. The keys don't all seem to work. Is anyone willing to look at it for me?   I took the keyboard out and removed the key caps but the switches are soldered to the board. Not sure what I need to look for. The switches seem to press down properly
