Sounds like you have bad solder joints on the vertical ic which should be numbered IC501 on the board.also there are capastors that coud be going bad but i would look for bad solder joints on ic frist.
The capastors numbers on board are C502 / C516 also need to check R 483 which is a resistor.
resolder the ic if you know how to solder. That is a comon problem a lot of tvs out there have. The only thing is the tv has high voltage on it even if it is unpluged from the wall. Some of the capastors hold there voltage for a long time. Be sure and unplug tv before you try anything if you are going to do it yourself and stay away from the capastor in the AC line should be marked 200 V or moor.

I turned my television on then it made the tv frame made a noise!and now the screen is black except for this thin line across the middle of the screen which is display the picture


Most likely the vertical oscillator circuit has failed. As CRT televisions have gone the way of the dinosaur, my advice to you is to give a fond adieu and invest in a new TV.

LG 32LH30 LCD TV Problem


IMO Seriously for $119 it's not worth it.
However, it does sound like a capacitor problem
If you are "Serious" about fixing I'd find a TV repair Forum.
Else I'd go here and get a new one.

SANYO TV Picture


I just bought a new Sanyo DP19649 and we can watch it for about 15 minutes then the screen goes black but the sou nd stays on. We have to turn it off and turn it back on to get the picture back for another 15 minutes-then it's the same thing all over again. The sleep mode is off and it isn't on automatic shutoff.

The Picture on my Mitsubishi vs-60805 "shrank" then disappeared


it isnt worth it, your verticle diflection is out, that board is about 3-4 hundred, and you would probabily need a service center do it(messing with like 30000 volts)and they will probabily charge around 200

Picture on RCA TV shrinks to a horizontal line


Hello,
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps
