If my memory serves me right, once the tape drops, the carousel should automatically pull the tape out of the cartridge and around the rotating video head assembly.
With what you have mentioned, that's the lesser problem. the real problem is the tape being fully loaded around the rotating head assembly, with no response (no play, rew, ff, etc) from the front panel.
So, there should only be a few things that would prevent auto-load (full tape out of the cartridge and around the rotating video heads assembly).
Two things to check, one is a lamp....Ok, I just read where you had replaced a sensor lamp. Was the replacement an original. Because not any lamp will make this circuit work.
Also, and since the unit has been sitting for a long time, I would suspect one of the contact switches being oxidized or not making a good closed contact. You would need a few very small clip-leads to check this out. And once you're able to get your hands on them, you'll need to connect them on each of the switches-one-at-time, and complete the contact yourself once the tape drops.
