Arrgh! I wrote a long response and then I got a white screen of, "I lost it all." The purchaser did put the pcb in the mail one day after Ebay's suggested mail by date. Now I just wait to see if it is the same pcb I sent him. I don't know if it will help me but I have posted the picture of my marking on the pcb to several sites, even maid a faux ebay listing (showing the markings on my pcb) with a very high price so no one will buy it. I worked at at electronics repair center in the 80's and early 90's, I did all the VCR repair, which was all component level repair. It was a great place to work, the owner was an authorized service center for over
80 companies, which meant we had service manuals for most of them. I performed service on over 11,000 VCR's in the 10 years I was there. It's common to have the same problem, so after you have repaired a few, you know what it needs by the customers description. When VCR prices got near $250 to $200, people started making the decision to buy a new one rather than repair. I had thoughts about DVD repair, but glad I didn't start that because the prices came down quick on those. I got out of repair and moved to Florida. My timing was pretty good, I told one of the other tech's I was leaving and he might want to take over my repairs, (I made the most money at the shop), but by the next year when I visited he said he was only coming in 3 days a week, and had another job.
