It is going into error protection mode. I will assume this is a power supply issue. The power supply with have blown ("popped") capacitors that can not make the proper voltage for your other components: EX: backlight inverter, Tcon board, etc. You will need to open the back of the tv (after allowing it to sit unpluged for 12+ hours) and look for the power supply board. The board is located dead center of the tv looking down onto it. I have attached a picture for what you need to look for. On the left is a healthy capacitor and on the right is a popped capacitor.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This tv have a colors wheel,hear loud motor noises,humming noises,squiling or grinding noises,have pictures black and white.All these causes are by the colors wheel is worn out, warp rubbing against it motor or fiber plastic glass briddle about to brake aparts.Don't turn this tv on anymore until,u change the colors wheel or u will damage the projection engine.The colors wheel are hard to change for amatur and hobiest.Because involved taking out many machanical parts,before even can come to the colors wheel to take out and change it.The best course to to hire a Tv Tech.to do this job.The price colors wheel part and labors.Awhile back was about $500-550,now??
