YouTube is great for these kinds of things. Avoid the "Hey Guys! LIKE AND SUBSCRIBE" ones with one minute logo intros, and look for the 5 minute ones where the old bearded guy gets right into the job.
I don't really subscribe to any channels or particular people. Do a few searches for the model number + words like "repair" and "DIY", and skip anything where the production value looks better than your 1992 summer vacation VHS tape.
