as you say that color came back for 15 minutes then went off. this is a clear indication that there is a loose contact or pcb crack somewhere in color section only. if that happens to be ok then check 1 antena or cable socket loose 2 loose connector in color section 3 print open or crack near chroma signal processor. 4 loose near color control. 5 chroma ic night be defective. if you are not tech person take the help of tech.person.

The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.
