Re: DVD player is locked

Press and hold the Track Down button on the player
Press the Power On button to turn on your player
Wait until the machine shows "----" on the display
Release the Track Down button on the player
Using the main remote keypad, enter the digits 1, 0, 1 and 1, then press Enter
The machine should now display "D-00" and be region free

Enjoy ;)

Re: DVD player is locked

Well, more information would be nice, but locked as in it wont open could be due to fact that somebody jammed it back there or a disk popped out, to fix this you could call a repair man or get a thin pair of siccors or screwdriver to pry it open.

Remote is working ,but DVD player button is not working and I could not eject my disc from dvd player.

DVD player drawers are generally driven by a small rubber belt that either falls off or breaks. Easily fixed by just looking inside the unit and replacing the inexpensive belt.

I have a Philips HTS 3371 DVD home theatre and can not play many DVD's as it give wrong region error. Can you please provide the unlock code and how/where to enter it to get it fixed?

Hi -

Please follow the instructions below for unlocking your Philips HTS 3371

Please note: Unlocking a DVD player may invalidate the warranty. Unlock sequences may not work with some firmware updates and some DVD players have been damaged through failed attempts to unlock them. Unlocking your DVD player is done at your own risk.

1. Switch the DVD player ON
2. OPEN the disc tray
3. Key 9 9 9 9 0 using the Philips remote control supplied with the player
4. Press PLAY. The disc tray will close.
5. Switch the player OFF then switch ON again.
6. To test, play a disc from a region which was previously locked.

If it does not work the first time, switch the player off and back on, then try again.

This is a verified unlock method, but I was unable to confirm whether it works for players sold locked to Region 1 (North America). If you have a Region 1 player and the method above does not work, you will not be able to unlock your player.

DVD player won't turn on after power outage

Hiya, sorry to say that the power supply is probably damaged, sometimes happens with power outs. Unless it is expensive model, they are sometimes not worth fixing (although the fault could be very simple like a single diode etc. Maybe send it in and ask for a quote, then decide if it is worth it.

Best of luck

My dvd player is locked

If you are unable to get the tray of the dvd player open either the player will have a hole in front for you to stick a (I use a straightened out paper clip) into and press in towards the dvd player. It will manually open the drive so you can retrieve your dvd or there will be enough of a lip on the tray door you can grab it and pull it open manually. Then I would try unplugging the player and waiting a few minutes and plugging it back in and you might get lucky and it may never happen again. Good luck . Hope it works.

to play discs from different regions on HTS3548:

Before you begin, ensure you have connected your DVD player to your TV and both have the power on. Once you have connected the TV, follow the instructions below.

-- Open the disc tray
-- On the remote control, press in sequence:
Disc Menu
7 3 4 4 6 6 0
-- Make sure Region 0 is showing on the TV.

This should hopefully help!!!!
