There is three flashing lights\r\nwhen it starts

This is a common fault with the 360, it says that its a "general hardware failure" which could mean
anything
really. In truth its the lead free solder that cracks with so much heat and as a result the Xbox 360 fails
causing the 3rrod (3 red rings of death) or e74 or even no sound but graphics or sound and no graphics
just like you are reporting.

Firstly get a spare AV cable from someone else, try this, if that does the same then try a different
SCART
input on the TV. if all this fails you need to fix your machine as it WILL get worse

You will need to get a 3rrod repair kit or get someone to fix it for you, there are guides available on the
internet. I'm in the middle of producing one right now that I will make available free of charge for all fixya
members.

Yes, if you switch the Xbox 360 on and are getting 3 red lights then you have the red lights of doom.

It happens because the GPU and the CPU overheat and then the soldering snaps off and you are left with this error.

To fix it all you need to do is send it back in to Microsoft this will take about 4 weeks to get fixed or you can fix it yourself using a good guide

Are the lights red or just green when it starts? If red then you my friend have the red rings. You can fix it sometimes by unplugging your console and wrapping it on towels for about 10-20 mins then starting it back up again.
