1. Try to look for settings for TV pictures. Some digicams have 'em. If you use a "daylight" setting, chances are excellent that the TV pic WILL look blue, as they're usually set to a too-high (=blue) color temperature unless they're calibrated for a 6500K white balance.
2. Make sure you use a tripod.
3. If you can select a shutter speed? Make it 1/30 second or slower. 1/15sec is very good for TV pix.
4. You may have to turn down the TV pic brightness if you keep getting overexposed shots...
5. ... or try a camera setting for snow or sandy beaches. Then the camera will compensate for very bright images.
Good luck!
