The TV starts up normal and after a few seconds will start to alternate between a blank black screen and a normal screen. It will alternate at about 1 second intervals. Also it will not complete an auto channel scan.
Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

What you all need to do is get away from a coax cable connection. If you have a cable box, or satellite box, take the coax cable off and use red, white, n yellow rca composite cables to connect your recievers to the tv. if you dont have a cable box, either get one, or get a converter box and use a tuner outside of the tuner within the unit. The tuners in those tv's are built to show you when you experience signal fluctation(which is normal with a coax cable) and thats why the box keeps popping up on its own. good louck to you all with this problem

mine does the same thing, before... it would come on when i turned it on & off. But now it blue screens then blank black. Blue means if it stays blue & i turn on my computer it will show all the computer stuff, i have not used TV yet.. But if you can get it to stay blue you can change things with the cc control, or swap..
If you find how to keep it blue let me know please..

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.
