On my Sony DAV-S300 DVD System, both C 13:00 (dirty) and "no disc" (recognition) problem errors are happening more frequently. I've run a DVD Laser Lens Cleaner from RadioShack (should that matter?), cleaned suspect DVDs...no joy. It plays after repeatedly inserting the same disc sometimes for 10+ minutes for no particular reason, other than maybe holding my mouth a certain way. 
So I went to try and recalibrate the DVD Player System according to a few good instructions on http://fixya.com , but pressing "Title, Clear and Power" in sequence all within 5 seconds, cannot get the "Test Mode Menu", to come up. It just turns on the default DVD screen page and shows "no disc". I have a factory Sony Remote RM-SS300. Are there sequences other than the above (pressing: "Title, Clear and Power" to get in to Test Mode Menu with differing remotes? Anyone?
Thanks
