Greetings Rich..
First of all it should be stated that as inexpensive as these VCR decks are now days, you MUST have a lot of time on your hands! I believe I've seen the local Sam's warehouse store selling the decks for around $25 - $30 now. Other discount warehouse type stores will also offer the same with nearly all these decks now coming in from China. The point of this is to ask yourself whether it is cost-justifiable to put in all this effort when you can buy a brand new deck for not a lot of green backs. Additionally, it can be rather hard to travel the highways and byways of the electrons without [at least] a good idea (at the logic gate / analog level) of what makes a VCR tick. Of course, a manufacturers schematic / parts list in hand wouldn't hurt either. Even better Rich, a service manual for the specific piece of electronics under repair. Years ago, besides the manufacture were the Sam's Photofacts people that used to do this - no longer. Why? I suspect that it's hardly worth it any longer when the entire deck (new) is now selling for around $30. If at all possible, I would attempt [at least] to get technical schematics from Hitachi for your specific model. Short of that, I would inquire if parts for this deck (especially any specialized parts) ARE still available from Hitachi. If not, you need to ask yourself whether it's worth continuing or not. As an alternative, there are several very good books on general VCR repair listed below. They can often get you rolling in the right direction of repair and alignment. They're certainly worth being on your bookshelf IF you do this very often. You may want to inquire with your local public library since they MAY have a copy for you to check out. These books will also detail the test equipment that is necessary to do an effective job at not only troubleshooting and repair but alignment too.
