Xbox 360 rrod question

My 360 got the rrod a while ago. I preformed the heat sync fix shortly after and its been fine for about a year. Now today I played my 360 and turned it off when I was done, I came back later and had 3 flashing lights when I powered on. It’s different this time though. It turns red almost instantly after powering on and only the bottom right light is not lit. Not only that but no video is displaying on the screen at all. It’s as if I don’t have the video cables plugged in.

I checked all connections and tried a new power supply. I looked around online but I couldn’t find a solution for these types of rrod symptoms. Has anyone else experienced this? If so is there a fix that I can try to use on my own?

If you need any more info let me know. Thanks
