Lines on TV Screen

I was getting blue circular lines in the screen when there was a solid colour on the screen. Now there are both blue and red circles. Is this a sign that the bulbs are burning out?

Depends on the TV model, if this is a rear projection TV with CRT lamps, that means that either CRTs are not aligned (fault on convergence board) or one or more CRTs had blown.

you should do the following tasks:
Press the left side of the TV with your hand, if the colors got disappeared, fortunately the flat cable inside the TV causes the problem. But

Replace the video board, if you can find one. Letting it cool down will not help any.
