I tested diodes 1-5 on the circuit as well as Q1 and q2 which appeared to be still in spec
D1 is a bridge rectifier so its probably fine
D2 reads .5V forwards and OL reverse
D3 reads .6V forwards and 2V reverse
D4 reads .6V forwards and 2V reverse
D5 reads .6V forwards and 1.8V reverse
these were tested in circuit as the leads are so short, if i removed them i dont think id be able to get it back in.

D3-D5 on your VCR appear to be bad, because on diodes they're only supposed to measure voltage one direction, and you're measuring voltage (albeit a very small amount) in both directions, which tells me that D3-D5 might be part of your problem (and possibly something for me to check on my VCR as well.)
