Hi.
I have to agree with Graham and Ken. I think you may be expecting more than the machine can produce. If a customer brought in a machine like that for repair if it performed well on a soak test it would be sent back NFF.
In those days spending days on a machine for an alleged fault you'd most likely get a warning of wasting company time.

I remember one customer measuring every square on the test card and if they differed by any more than 1 millimetre he would demand a new set, and then go through the same again.
Often in VCRs and TV sets of the time there were compromises made.
Splashes on screen are generally earthing or the signal level off tape being slightly low, this could be the heads themselves too, slightly low record level or even incompatibility between different machines, some of these things can be difficult to resolve and remember if there are too many drop outs due to low signal the drop out compensator will struggle.
Again in IMHO that picture looks pretty good to me.
