At first it was lots of horizontal lines over the screen, and later TV screen went completely black. The sound still is perfect. Perhaps I just need to replace the fuse? I love this TV! Thanks...

You have stated that your TV has a lot of horizontal lines before it went off picture. We say that lines as retrace lines. So many of them will there on the entire screen, at about one inch or so apart, horizontaly scattered along with picuture. At that time, you may be unable to down the brightness control also. Even though you have reduced the brightness control to zero position, there will be some brightness level on the screen. You should have to repair that fault at the begining. There is a voltage going to the picture tube base, known as screen voltage. That voltage determine the emission of the picture tube, and we call it a bias voltage. When it goes higher than normal, this trouble ie retrace lines will occur. In long run it may spoil the picture tube itself. I don't know what the case of yours.
Anyway it is best for you to consult an experience technician in this case. Ok.

CRT TV with only a horizontal line through the center of screen.


Yeah. Unfortunately you are right. It is normally the ic that controlls power to the gun. And it is expensive.
Your only chance is to find another model of the same TV that some is ready to trash or throw away at low cost and that TV having some other defect. Advertise in the local newspaper or other channels. It is worth a shot.

Picture is black except for colorful horizontal line across tv

It sounds like you need a DEFRAG Done. Have you put any new speakers or magnets near the TV? Has anyone had a magnet toy or things around the TV lately?

Problem with tv

Could be a horizontal output fault, faulty power supply, a simple dry solder joint or HVT. If you can hear arcing or smell an ozone odour, it will be the HVT which may cost a bit.

Without knowing the actual cause, it's impossible to say how much it would cost to fix it.... could be anywhere from $50 to $250 etc

Best to have it checked by a technician and get a quote to repair... then decide if you think it's worth it.

Toshiba is generally a reliable brand, so if you were happy with the picture quality before the fault occurred, it's probably worth repairing.

Picture is now a thin horizontal line

now only visible in a thin horizontal line. first of all you reduce brightness to monimum. it just to protect your tv from crt demage. your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem. your flyback transformer or horizontal output might be defective. but remember check for power supply is ok from surge protector hope this will help.

Green screen with almost horizontal zigzag lines

Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.

TV has bright horizontal line

do some voltage checking on the ic and make sure that volages are reaching there, about 32 volts. if it is reaching, then you can change the ic there. but before you do that, check around that ic and make sure everything is ok there. good luck
