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
There is a mechanical adjustment on the tubes themselves when it was dropped it could have knocked it out of alignment, or the Convergence ICs are bad with is a common problem with CRT projection tvs. Mechanically adjusting the tubes can be tricky I wouldn't suggest working on it unless you have some kind of experence with tvs. But if you do adjust the red and blue to the green.
Sorry to hear about your bad luck! Be carefull if this is a crt based tv you could get shocked messing with the wrong wires. If you send me a few pictures of the back of the set i will help you locate where they belong.
blue tube is very common on this type of tv, His prices are very fair.My concern is the other tubes i usually could tell if the other tubes looked ok. If he says they seem fine.And you like this tv it is worth fixing. Make sure if you do say yes you get a 1 year warr on tube and a warr on labor,
Im not sure if you got price with yoke assy to or just tube. It is very hard to put yoke in tube and have it adjust properly. make sure when you talk to him it
is a new tube and yoke assy , If not dont fix.
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

If you have a service manual or the experience to do this then I guess you can repair it. You do need a cross hatch generator to do an alighnment and sometimes an ocilliscope to adjust horizontal alighnments as per the service manual. Your paying for what the man took years to learn as repairing TV sets is not an overnight thing. As to the worth its up to you, do you wantt to invest this much money in a set that cost you a bundle?? How old is it? will answer your Question as they usually "made" to go for at least 5 to 7 years. After that its a crap shoot and if its older I wouldnt invest a dime in it. Unless you know how to repair it I would say buy a new one as the other tubes may go out a week from now or it could be 3 years from now as we TV techs are not fortune tellers. 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
