42pj550 GETS SOUND , but no image

[monera96]

I would like to thank everyone and anyone in advance for their help!

I got a 42pj550 by lg,

It get sound output but no video,

I followed a thread on jumping the ext aux point and it should start displaying test images , but even that doesn't appear to get an image onthe screen

When I plug in the tv, i hear a fast click.
When i turn it on i hear click click

as soon i go to change the channel, the tv shut down

Any idea guys?!

Thanks don't wanna throw away my 42 gaming tv!
