3 red sections on power switch

hello you have the red rings of death which means that your xbox 360 is overheating and need the rrod repair if you have brought the xbox within the first 6 months you can send it back to xbox and they should repair it otherwise if its older than 6 months old there are people that repair consoles

Typically this is a heat issue. I had the same problem recently. I was able to fix mine by adding a 5vdc fan internally mounted on the GPU heatsink & removing both heatsinks from the processors and re-applying heatsink compound. Before trying any fixes though be sure to contact microsoft and see if they will fix it under warrenty.
