The vhs player works 100% along with the buttons. But I do not know how to test the record button. The DVD player worked at first but then stopped working when testing, but then went back to working as should. It might have just been the disc i used to test it, but i dont think so. All the buttons worked. I do not know what the tracking buttons are for or how to test them. The only input connections that were tested were the DVD/VCR AV output connections. (last photo) The DVD player also makes what I think is a strange sound.
