Pdvd880-----invalid region - Venturer PVS177W Portable DVD Player

You can make the Player to play all-region DVDs [not Blu-ray discs]. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Procedure to make it region-free to many DVD brands are given.

factory reset the screen

This means that the region code on the disk (which determines where it may be played) does not match up with the region of your DVD drive.

Normally the region code can be changed, but only a limited number of times.

Try to make that if you buy a DVD online, it has the correct region code for your player

You can not fix this, DVDs are coded in such a way that a for instance a DVD sold in the European market can't be played on a DVD player sold in the USA. You can buy region free DVD players, but they are not sold at the local electronics stores, they are available on eBay I'm told.

i have ku4000 lg cyon show but the problem evrytime insert the sim card invalid card the phone is from korea i need ur help pls what can i do?

Make sure that in the Windows control Panel you have given the correct selection of your Country in "Region and Language" or "Regional Settings" .......

You can make this player REGION FREE so all discs operate on it.

Power up, no disk in. Status says READ then INSERT DISC.
Press MENU (status reads invalid key icon)
Press 1 (status reads invalid key icon)
Press 9 Menu is displayed.
Press ENTER on the region, digit turns to "-"
Press 0
Press ENTER again
Press EJECT to clear the special menu.

If you reset (unplug) the player for any reason - this will need to be re-entered.

Thanks for using FixYa!!

If you go into your factory settings setup screen check there for what region its set to and if it is possible to change it, change to the correct one.

PS If you're gagging to get at this and the remote doesn't work, pull out the tab that isolates the supplied button cell in the remote control :-)
Region 1 NTSC
Region 2 PAL
Region 3 NTSC
good luck
please mark the post with a fixya!

Did you get this working? If not, then your DVD isn't supposed to be region free in the first place, and I can send you a firmware which I have used a hack in order to make region free. You can then take this firmware and follow the same instructions you used for the other firmware.
