If you've already cleaned the player with a good quality commercial DVD cleaning device then you have done just about all that a typical user can do short of taking it apart. I just had a real nice DVD player die last weekend and was surprised to be able to pickup a fairly decent DVD player/recorder for under $80. I also noted that a basic DVD player (also played audio CDs) started at $30. On the one hand the old one cost over $150 a few years ago and I hated to just give up on it, but for $80 I got a new unit that recorded and had one year warranty. Had I taken it to a repair shop it would have cost at least $40 with no guarantee other than 30 or 90 days. Have you considered just tossing the old one and purchasing a new one?
To find the laser remove the cover, with the dvd tray open. now you may have to remove the piece of plastic that covers the dvd when it plays. below that is your laser. the lense itself is about the size of a pencle & clear plastic. cleaniong the laser with a swab is a lot better that relying on those lens cleaning kit you can get. as for the ic i don't know what you mean? good luck.
