Component input on my TV went, took PS2 cable with it.

One of the component inputs on my TV went several days ago. Nothing works in that particular input anymore, and the TV detects that cables are connected when they are not. Input unavailable normally, always on with "No signal" now.

The TV isn't the issue, it's still under warranty and I'll be calling a service center next week.
My real problem is it appears to have killed my PS2 component cable as well. My PS2 still works fine with regular AV cables, but damn it looks like ass that way.

Are there any components in these cables that may need replaced? There's a big plastic cylinder near the connector end, but it's sealed closed and I don't want to go cutting it open if it's nothing more than a ferrite in there.

That normal composite video still works in the PS2 isn't an indicator that the component cables are bad. There's an outside chance that the component output on your PS2 is gone, especially if the failure on your TV was due to a faulty ground or a short. You happen to have another PS2 you can test those cables with?

Tested the cable on my other PS2, just plain doesn't work. Pretty sure it's the cable.

Looks like it's time for the tedious multimeter test. Not only do you have to make sure that every pin on the connector leads to a plug, but you have to make sure that there's no short by making sure every pin leads to *only* one plug and no ground. It's easiest to clamp on lead to the plug end and then take the other to each pin one after the other, making sure that you only get one continuity path. That's when you can start to decide if it's worth fixing or if you should just through it out.

To answer your other question directly, there's really no components in there. Worst case scenario, you might have a short or a melty point that needs to be cut out so you can splice the remaining two pieces back together.

Why I didn't think to break out my MM I don't know. I just assumed there was probably some resistors or caps in there that might have went.

Off to test with MM now.

Ok I went over everything with my MM and it checks out except for one thing. Checking the green line gives results that fluctuate. On diode mode it checks out clean, but if I set to x200ohm it's all over the place. From 0.01 to 0.67 and sometimes flies right to INF.

I plugged the cable back in again, and this time I got a picture, but everything is tinted green. Sync is on green with component right? Might there be a capacitor hiding in that line? I know no other explanation for such a variation when testing resistance, but then again I'm no expert!

Mind you, if that lines the problem why is red and blue missing? Green I know, on component, is "everything else".

Edit: I fixed it, after cracking the housing on the connector, I can see why the ground pins test ok on the shielding, as they're wired right to it. From there, the video ground was making intermittent contact with the pin it's jumper across from the other grounds.
Looks like the wire was blown right apart out of the insulation, as the insulation was still in one piece, just with a hole in it and a split wire hanging out.

Soldered it back together. 100% fixed! Now to figure out why the hell my TV did this......
