My xbox 360 has no video.. [Help]

Well i recently was playing my xbox 360 and the screen began to go blurry, so i restarted my xbox and i heard everything through the tv, the normal sounds it makes when the xbox starts up but no video showed on my tv. It was still black. I thought it was my tv so i switched tvs but same problem. I also thought maybe the setting switch was on hd, but it wasnt. So then i though it was my av cords so i went and bought new ones but it wasnt that. My warranty has expired for my xbox so does anyone know any ways i can fix this myself?​

 

I had the same problem. Its the GPU, the solds are bad. You can try to turn the xbox on and wrap in a towel. It worked for like 15 minutes for me but then went black again. I called xbox and they said it would be 100 bucks to fix it. So i called again and lied that i got the RROD and they fixed (sent another one) xbox for free.
