DVD Player freezes frame in middle of disk and then stops

"No Disc " message on different disks usually means a lens problem, as already suggested you need to access the lens pickup after removing the dvd cover, and to clean the lens with Q Tips and isopropyl alcohol.

This kind of maintainance should be performed by a technician , if you decide to do it yourself, unplug the unit before servicing it, and be very careful.

Hi and welcome to FixYa,

Based on your description and since the error happens on the same position, possible a mechanical problem with the traverse mechanism. This is the metal rod that the lens carriage move along from center of disc to edge of disc. Pls reference below image.

Corrective measure therefore would require opening the unit, locating and cleaning this metal rod and all other attendant mechanism/parts including the worm gear and re-application of appropriate lubricant.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

U saying that the prob is in disk or in the player?

Try a dvd lens cleaner, if a cleaner doesn't work you possibly have a fault in the dvd drive or on the lens, hows your JVC warranty? 

Hi

Have you tried cleaning the disc itself and do you have a lens cleaner for your unit. Keep us posted. Thanks
