It may well play NTSC disks but it won't convert the standard to PAL or whatever your system is. Check your TV will display NTSC 525line pictures with 30HZ frame rate.
I would guess it is either overheating, or someone has a Samsung next door and your remotes are the same. :>/
For overheating, go around the back and side vents with a vacuum cleaner with the small brush attachment on it.
no there is no magic button, I would replace battery and if that did not work buy a universal remote or Toshiba remote. they are readily available on line.
