rpi2 not working with my old CRT TV

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.

Hello, I am using LG slim magic flat TV (model: 29fd5rge) and its close to 7years old.

Thanks,

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".

When I change the input, I can only see AV2 on top right corner nothing else completely black screen and when I change mode(TV/AV) using remote I can see other modes like AV1, Component and S-Video.

Thanks,

You're welcome.

Strange that it goes from TV to AV2.  I have found with some manufacturers that you have to select an AVx input, rather than Component.  Have you tried powering your RPi up and running through all the input modes on the TV?  I would even go so far as to leave the audio conns unplugged.  That shouldn't make a difference, but I've seen some few CRT sets that ended up with grounding problems when the audio was plugged in.

Hi, when I loosen the 3.5 mm jack I can see booting and Rasp logo,  but it's flickering it's difficult to make out something.

Ah. That says the GND is the sleeve and not the next first ring. You cannot use this cable and must get a cable with GND on the ring. You have a video composite cable which does not work.
