No picture when I load dvd, screen reads 'loading' for a while then it says 'wrong disc'. It was working fine yesterday.

Check and replace the Laser Pick-up unit of the DVD player. It is weak. Contact any service technician. This work cannot be done by a user. It is somewhat skilled one.

if the disc is read by the player the tittle menu of the disc should appear at the screen and the player is ok you just need a remote control coz some disc/program need to start through remote program

the laser may be broken,and can not read...

no try to open the cover and inspect anything stuck in loading mechanisum.check the all reed swiches and clean all if they are dusty.

Wish I could. I have the 4600 combo and the VCR works fine. The DVD stopped working many months ago and just yesterday started working fine again. Worked fine for two days and then stopped, picture froze, and all I got out of it, is the picture is loading. Wont give me back my DVD nohow, so have opened the case and stole it back. Tray will not open at all. Trying some repairs, will holler if succesful

I had the same problem but I solved buying "Laser Lens Cleaner " Philips Magnavox after 3 attempts the DVD starts to work fine again. First only 3 min, then 10 min and now the entire CD cleaner and after I left the CD cleaner for 15 min I tried to play the DVD and WORKS!!! perfect!!!

two DVD player with same problem. I think they are disposable. :(

Load the right format of disc
