In a crt television, you have a special power supply for the huge voltage for the tube. That can be defect, but also the heater in the back of the tube can be defect. Actually more defects can make the tube is not working, while the receiver and the audio part still work fine. Could be a little thing, like a bad soldering place on the mail board, but be aware it is dangerous to open a CRT, because of the very high voltages. (Up to 30.000 volt on the tube) and the voltage can be there on the tube and in capacitors.
Don't spend to much money for the TV, because the new flat panel TV's are not that expensive anymore.

That television has no digital reception capability. You need to get a digital converter for it. The format that is uses is called NTSC and it is no longer being transmitted in most places.

Without a remote control, you can't program it. If you wish to buy its original remote control, you have to contact the authorized service center. If you wish to buy a universal remote control, you should know about, which brand remote control have setup code to your TV/device brand. You should first make sure about the number of digits in the codes to your device have. There are 3-digit, 4-digit, 5-digit and even 2-digit codes. You can get this detail by the code list attached to every universal remote control. The brand name of the remote control you select isn't a matter; but, its code list should have setup codes to your TV/device brand, otherwise you can't set it up with your device. For more information; check the links given below, and find which brand remote control has setup codes to your TV/Device brand. Setup code list & setup procedure to some popular brand remote controls are given. Check it, and determine which brand remote control should be bought, and buy that brand remote control, according to availability.

Hello
Total failure of vertical sweep occured whic your JVC TV. There are mainly two resons for this fault.Loose soldering terminals of the vertical output IC is the first one. The second one is of failure of the vertical output IC itself. You have to locate this vertical IC. It can be located at the main board. Vertical IC will be screwed on to a metal heatsink to radiate heat from it while it works. You can identify it very easly, if you have knoledge in electronic circuts abd printed circuit boards.
Resolder all the solder terminals of this IC first, by applying a little more solder; without making any solder bridge short in between the close adjecent solder terminals, and see whether it helps you. If not replace it with same type and number. OK.
