A bizarre coincidence but our Sony DVD player DAV C700 did exactly the same when the kids were watching a DVD. All other functions on the system are still working but the DVD player wll not eject or play - and the self diagnosis function C 81 remains illuminated on the display.

Problem traced to Samsung's Anynet+ System interacting with LG's Simplink. They seem to be
compatible. Cured by Menu/Option/Simplink/OFF. Hope this helps with anyone else having this problem. trev6.

the problem has to be from the display inverter board. The display inverter board is responsible from bringing display on the screen. Now since is no longer display, then it mean it has become defective.
Get a philips screw driver, disassemble the unit in order to get to the display screen. You will see a kind of flex or wire connected to the screen. The board where the wire/flex is coming from into the screen is the display inverter board. The board is rectangular in shape.
Remove the board, take it to an electronics parts store within your vicinity for exact replacement and the unit should display again.
Keep me psoted if you need any more assistance on this issue.

Typically a no disc display indicated dust on the optical unit ( lens ) or failure due to low laser beam emission. For the first case you have to remove the top cover and clean the lens very gently with a ear bud. The the cleaning does not solve your problem you have to replace the optical unit itself. Unless you have experience doing the above i won't recommend it. Replacement will cost you about 15$ plus labor.
