The good news is that you did not do anything wrong.
The bad news is that this is a common fault with this model and will need to be sent back to the supplier for a firmware upgrade.
Disconnect the unit from the power source for 15 minutes then reconnect and it will come back on, however the problem will come back again as it is a firmware fault.

The display screen is rolling and is in black and white.


Hi

You switched to PAL mode from NTSC or vice versa. Most DVDs will only output PAL or NTSC, not both. So even if the disc is region ffree, the fact that it's encoded in PAL (50hz) makes it appear like you describe - no vertical hold / black and white.

Some set top players [Apex, Phillips] will convert PAL to NTSC on the fly or vice versa.

Remember, PAL/NTSC is not the same as Region.

Here's some detailed info:

http://www.sjbproductions.com/web_pages/tip_video/ntsc_pal.htm
http://www.dvdcity.com/codefree/codefree-ntsc-info.html

You can convert the DVD to NTSC, and strip the region code by following http://www.videohelp.com/guides/how-to-convert-interlaced-pal-dvd-to-ntsc-dvd-id1107#1107

Most players are either NTSC or PAL, however increasingly DVD players from the Far East (Apex, Phillips etc)


, which is 50hz instead of 60hz, hence the lack of vertical hold

How do you change the DVD player mode from PAL to NTSC ?


I just found the way to change the setting from PAL to NTSC.

While the unit is turned off , press the EZ View button on the remote control. Press alternatively the select between the PAL or NTSC setting on the unit display. That's it.

anteetina,

most probably your problem is within color system settings. It's either PAL/NTSC or PAL SECAM signals being produced by your player.

1) try to check your TV screen with regards to color system it use, check the color setting if it does indicate "Auto" "PAL" or "NTSC" try to choose "auto" and see if any changes will occur.

note: you can also check the service manual of your DVD player of what color system it produce and if it's match with your TV screen

cheers.

Can't display Pal on My Sony 57" KP-57WS520


There are probably a few problems here. What are you using to play the disc? Some NTSC players will "play" a PAL disc but interpret it as NTSC with the symptom you are describing. You need a DVD player that will play PAL. Many of those will output NTSC directly when set up to do so. The other alternative is to have a PAL compatible player that will output PAL into the converter. To narrow this down specifically, please post the model numbers and the connection scheme for your equipment. Once I understand your current setup, I should be able to describe a method to get this to work for you.

Nope. The AV inputs except a composite video signal that is either NTSC or PAL. You will need to convert the PAL signal to NTSC.

It's likely to be an incompatible signal. You have PAL (UK) and NTSC (Belgium), the DVDR/VCR combo may not be compatible with PAL causing it to seem like it's not receiving any signal, when in fact it is - but not in a recognisable format. You may try and get an NTSC to PAL signal converter like this: http://cgi.ebay.co.uk/NEW-TV-AV-Video-System-NTSC-To-PAL-Converter-Converor_W0QQitemZ270163920912QQihZ017QQcategoryZ32837QQtcZphotoQQssPageNameZWDVWQQrdZ1QQcmdZViewItem That'll solve your problem.
