Please check the type of plug since they vary at http://www.raspberrypi-spy.co.uk/2014/07/raspberry-pi-model-b-3-5mm-audiovideo-jack/

I assume you're using the 3.5mm to Composite cable such as at http://www.mcmelectronics.com/product/24-15489 since this is a RPi 2
If you need a more comprehensive reference there's an excellent one at http://www.raspberrypi-spy.co.uk/2014/07/raspberry-pi-model-b-3-5mm-audiovideo-jack/

The link you have in your post is for the the older systems that had separate video and audio outputs.

Thanks GreenBeanie for adding your link to mine. Note that some types of plug have different order of GND. The GND must be on ring2 nearest sleeve for Raspberry Pi to work. One of these camcorders will have video on ring1 instead of on the sleeve meaning switching cords to work.

Thank you Clem and GreenBeanie , Yes I am using 4 pole 3.5mm jack to RCA cable. I have used the same cable for another AV monitor and it's working fine with out any issues.

Following cable I have used:

and also I have tried swapping red plug as composite video input instead of the yellow one, but no luck

Thanks,

If one AV monitor works and not the old CRT TV, I would suspect the brand or age could be a problem. Can you say what you have brand and age?

What is the exact model of your TV, Nageswara? There seems to be an LG OEM Composite Cable for some models, that does more than just change the colors of the composite inputs. I'm assuming that there is a difference in the impedance that's enough to cause video problems with a standard 75 Ohm input; but that's just a guess. It's a 3.5mm to YWR female cable.

You might be better off with an HDMI cable and an HDMI/Composite adapter. I saw an HDMI to Composite on eBay: http://www.ebay.com/bhp/hdmi-to-composite-adapter

............or............. an electronics project?

This is a screenshot from LG's generic "Color TV" manual, showing the hookups. When you change the input on your TV from regular TV (or cable, or whatever), does anything come up on the screen? Typically you'll get a box stating something like "No signal".
