No picture using component on Toshiba 32HL66

If you are using the Red/Yellow/White cable, that's composite cable, but if you're using the one that's Red/Yellow/White/Blue/Green, that's called component. So basically, you set your TV's input to the corresponding color match. 5 colors: Component, 3 colors: Composite.

Did you switch the Xbox HD switch to the off position?

Look like ur Xbox 360 AV RCA cables is not making contact to the input board very well.Take some rubing achahol cleans the all those input holes,take the RCA AV connections make couples twises to the red,yellow and white,will help.Make contact with ur input board it should work.

You say the component video is no good? Well this usually happens when it is wired up incorrectly, Ensure you have the right colors in the right jacks at each end, it is real easy to get mixed up... make sure Red goes to Red, Blue to Blue and Green to green, all alongside each other, NO ALSO using Component you MUST also run 2 more cables for the Audio, they are Red & White NOT the Red from the "Other" Video input, BUT the AV Red & White jacks, beside each other on the units. So all in all there are 5 cables taking the Video, 3 R, G, B. + The Audio, R & W.

To localize issue better try plugging your xbox into input for your ps3 and see what happens. You may have a bad input. Happens.

This might not help everybody but it might be a cheap fast solution to the "Xbox 360 no picture but sound ok" problem. I have old refurbished 360 that has had no problems at all. SInce I got it have used it with powerwave cooler attached to the back. This cooler has seperate Outputs for Vga, SVga, audio, component and av. Don't need the microsoft cable at all just standard cables. Always had it plugged in with VGA or SVGA cables and got great picture. I bought new 360 and put the old one in bedroom with old tv which only has av inputs. Got shocking picture that was unwatchable but sound was good. Tried all ways but no different. Seems the xbox plug has problems. If you get the powerwave cooler it splits the xbox output socket in to seperate outputs for everything so you can use it with Vga or Svga cables if your tv has those inputs and it should work fine. Only seems to be the standard AV outputs that have problems. Haven't tried the componet leads but I guess they might work as well. If you only have the old yellow, red and white AV inputs on your tv this wont help you but if you have the other types of inputs it might fix it. The powerwave cooler you should be able to buy for under $20 so it could be a cheap solution for this problem everyone seems to be getting lately. It works for me at least so get one and give it a try.

already solved it. thanks. i couldn't see the xbox settings blade because of the blank screen so switched my component cable to the tv setting instead of the hdtv setting, then i could see the dashboard in non-hd and switched the resolution to 720p while simultaneously switching the component cable back to the hdtv setting. that worked.

Probably your G-Hyper board. You will need expert servicer and should cost about 3-400.00
