Re: LG CRT TV Problem
It sounds like your picture tube is either shorted at the blue gun or there is a blue drive problem. The blue driver transistor can short and cause the same problem. If it has little fine white lines as well, most likely it is the tube. Thanks for using fixya.

Nice big screen but CRTs are getting old So, if you can't set correct colors with your Hyundai it might have some serious issue with tube. Probably replacement might cost you more then a new new 27" Flat Panel. See some tutorial and info about bad color of CRT
