My crt tv no pics but good sound
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.
STOP TV FROM TURNING OFF AND ON
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience.

JVC AV-27820 turn on the a white line accross
HelloTotal 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.
