Probably have the wrong "Source" selected... it's most likely still looking for the input from the camera which I assume you are no longer looking at. Blue screen is the "screen saver" mode when there is no signal.
Hi and welcome to fixya,
it is the colour wheel problem,,,,,,,,,this is common problem please check it ...it may be also cathode ray tube...
thank u.........
the problem will either fix itself out or the screen will go. chances are one color goes then the next and then its toast but can go after blue as well.
On your TV set remote are you selecting the proper input; for example when you have different devices connected to the back of your tv set, dvd player, vcr, cable box etc; you have to tell the tv which device you want to use by selecting the right one on your tv remove input selection. Hope this was any help.

Make sure Initial is highlighted in yellow and press Enter.
