Cannot play disc - Sony DVP-NS57P

Open the case. Disconnect the ribbons from the main control PCB. Remove the screws holding down the PCB and the rear connectors. Take the board out. Find a chip with the number MR27T1602L or similar - it is called a P2ROM. Run a screwdriver slowly all around this chip to possibly drain erroneous (yea right) data. There is a small chip diagonal to the P2ROM right next to it. I could not read what it was but i suspect it is for temporary data storage - possibly a serial ROM of some sorts. Run the *SMALL* screwdriver around the 8 legs on that chip slowly ensuring that it connects each 2 legs to each other along the way. Now this will either 1) Do Nothing 2) Mess up the chips or 3) Clear out any bad (read factory installed failure timers) data from the chips. Doing this task over a period of about 3 hours seemed to have solved the problem. Now it could have been as simple as disconnecting the ribbons to the board and leaving it sit for a few hours to drain (memory caps to lose charge). I don't know. But I know after doing this my player started working again. Good Luck to all who try.
