Does Color Flickers in Your TV?

Three weeks back, I bought a brand new DVD player, Onida DFX-7410.  Using AV1 port(RCA), I connected the DVD player to TV(SAMSUNG CS21M50MEELXTL) and when a DVD was played, everything was perfect, except for the color. The color was flickering.

At first, I give my thought, over the probable causes of this fault. It has to be one of the following.

1. Faulty DVD Disc
   This was ruled out,when I tried with several other DVD Discs. All the DVDs faces the same pattern of color Flicker.
2. Faulty Video Cable / AV Port of DVD Player
   This again was ruled out, when I took the DVD player to my neighbour’s home and played the DVD. There, the picture is fine without any color flicker.
3. Faulty AV Port of TV
   This was the last one in the list, I doubted on this, as the TV was 2-3 years old.
   The TV has 3 AV Ports: AV1, AV2 and Alternate RCA port for AV1. I tried connecting the AV cable to each of the three RCA ports, the same color flicker issue persists. So, I assumed the common circuit for all the AV port needs servicing.
   But this cause was ruled out when I connected my Camera Sony Cybershot DSC W300 to the TV using AV1 port, the Picture is brilliantly clear.
4. What’s that? Its DVD Format (NTSC/PAL)
   So there is something, that causes the issue when the DVD player is connected to the Samsung TV.

   Today, I googled to check about cause of the TV color flicker, I came to the yahoo Answers. Immediately, I switched on the DVD player/TV. I was looking for NTSC/PAL in TV/DVD Player ‘Settings”. I couldn’t find any option in TV, but in DVD player, there is a dedicated button ‘N/P’. I toggled it from PAL to NTSC, that resolves color flicker issue.

   So What really happened was,
   DVD Disc that I have played is of Format NTSC, while my TV is PAL one. My DVD Player needs to be set as NTSC to read the NTSC disc and convert the video to PAL so that my TV can understand.
   In the case of my nieghbour, His TV is an pseudo Systems, it can automatically handle PAL/NTSC, that explains why it worked in his home without setting up NTSC mode.

   Though India is the country where PAL is the Defacto standard, It doesn’t matter when it comes to DVDs. What really matters is that DVD format NTSC/PAL and DVD Region codes.
