Technics SL-QD33 problem

Turntables | Audiokarma Home Audio Stereo Discussion Forums - audiokarma.org
I seem to have a common problem on a SL-QD33 i recently bought (as-is). The TT plays fine manually. The platter spins if I move the tonearm over the platter. It wont stop spinning Unless I power cycle it. If I press START/STOP button, I either get nothing at all or I get a flashing red LED. It also stops the unit from being able to play manually as the platter will no longer spin if I move the tonearm. I have to power cycle to get manual play to work again. I've read a lot of the posts about issues like this and I have already manually moved the worm gear through it's range. All the lube looks good. Nothing is sticking. If I reassemble the bottom tonearm plate as per the service manual, the motor will spin a small amount as the large white main gear moves to its "rest spot" but thats it. Nothing else. This TT was worked on before I got it and the person didnt even put the springs back in the feet! I'm assuming nothing was "left out" of the lower tonearm movement mechanism's plate if it was gone through. I really need some high quality photos of what's supposed to be under there. The low-res B&W drawings in the service manual lack detail. There were some of these types of pics in another thread here but theyre no longer showing up. I also read a post where someone got this same problem solved by replacing the power supply, so ive ordered one of those from another TT that was being parted out. Thanks for any help!!!!
