I have read cases where the laser somehow got either too far in or too far out of its normal path. I think I read it in a thread talking about the u66 error? anyway the person took the cover off the unit, then the cover off the drive. He carefully physically moved the laser head position, put the cover back on the drive and unit and his error code went away.
Now I know your situation is different but as long as you don't force the laser head and break anything, I don't think it would hurt. BTW I've found the easiest way to take the cover off the drive is to take out the 4 screws and then lift the rear of the cover then slide the cover back a cm. or so and lift up. I've personally never had a EH-75 but I'd think the cover would be similar to the ES-15 of the same age, which I have.
To reinstall the cover slide point the front down and slide under the little pins and then forward. Finally pushing down on the back.
Note when you have the drive apart I would strongly suggest cleaning the spindle. It's the rubber part that holds the disc near the center. The lower piece(not on the cover) tends to get dusty and cause disc slippage which also causes problems. Who knows, maybe it's just the spindle that needs to be cleaned. The classic sign of that is scuffed center part of the discs(it should be totally clear) and grinding when writing to the disc(especially during finalizing and editing disc).

If you don't feel comfortable doing the above maybe you have a friend or relative who might be handy? Otherwise you could sent your machine into Panasonic and they will fix it for a flat rate of $130. A machine of your quality would sure be worth fixing.
Personally I'd try cleaning myself and if a no-go then send it in. Make sure to get it put back together correctly though, otherwise they might not like it that you took it apart yourself and possibly deny the $130 flat fee.
I can't tell you how many times when I worked in a radio TV repair shop we got in devices the customer tried to repair. They usually came in a basket including the parts they couldn't figure out how to get back in place

P.S. personally I wouldn't try cleaning the laser with any solvents or force. It's very fragile and I once ruined a player trying to clean the laser. For that I'd suggest a lens cleaner, although the lens cleaner does nothing to the spindle. For that you need to disassemble the machine.
