This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen. Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube. Local tv repair shop will help you for that. Thanks
This may be a bad crt or picture tube. Take a good look at the picture when it's on and see if it has a pinkish or greenish tint. This is easiest to see if you turn the color adjustment all the way down. If it looks like the tint is green or pink and the focus isn't great then it's probably a bad crt. Not worth repairing if its the tube.
check for bad solders on the crt socket . If it turns off again try running the tv with the crt socket off the tube but 1st try to time how it takes for the tv to turn off then disconnect the crt socket. If it does not turn off the tube may be bad, if it does not turn off check the voltages at the crt socket and see if all the voltages at the colour outputs are close to the same, if so then you have a bad tube when you connect the tube and the voltages change conciderably the tube is gone
This is a CRT type projection TV set. You could have a bad green picture tube, a bad connection on one or more of the picture tube sockets and or driver boards, or there is a RGB driver problem in the video jungle IC or the output driver transistors. If you have had any experience with solid state TV repair, there should be no problem figuring out whats not or is working in this set. If you have not had any experience, there is alot of high voltage on these picture tube sockets, and one wrong move and you will get a perm of a lifetime. That voltage hits you so hard, I have seen it make a grown man cry. Play it safe and call in a pro to assist you in this repair. Good Luck

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
