My Home Theater turn on but don't play the DVDs I think I need reset but don't know how

If it plays CDs and DVDs but not BluRays at all, then the blue laser is burned out. CDs and DVDs use a different laser. A needed firmware update would not prevent it from reading a BluRay.

The Access Code is 0000 as default unless it's been changed

I think you'll find if it's not playing Region 2 DVDs that it's the same old Philips fault in that the laser has gone / is going.

not playing dvd

try Resetting the system turn power off then press and hold stop button on front panel, power light will flash, hopefully this will sort it for you

is it a burned disk? if so your dvd player might not be able to play that type of dvd... i know sometimes also scratched ones won't play at all as well... of course also make sure everything is plugged in correctly and if it does this with more different dvds then there's something wrong with the player itself... which i hope is not the case as those are very difficult to fix yourself

change the motor disc spindle are loose their velocity thats why don´´t read the dvd´s

no you cant it is only an upconverting dvd player

There may be some dirt blocking the lens of the laser. They make cleaning kits, which you can get at just about any electronics retailer. If that doesn't work, you might have a defective unit.

you need to buy a cheap av moulator (about 20.00 at most stores) this will solve the problem radio shack has them and so does wall=mart

i need to know if it was playing cds before then i will be able to help, my email is [email protected]
