From your description it sounds like a yoke problem, you describe an hour glass picture which is a classic symptom of the horizontal sector of the yoke is at fault. The easiest way to test for this is a ringer tester, chances are it will show a short in the horizontal winding which causes the high voltage to load down and draw more current in the process.
U can't.Only horizontal lines on the top parts of the tv screen or the lower parts of the picture screen.Or very light horizontal lines mix in with the tv screen pictures.The "CRT" the picture tube is slowly dying of old age.Quicker than they supose to.The late 90" these problems case show up alot more in standard tvs using CRT tube.Because the CRT and analog design about to be faze out of the market place.The glass molding and those radiation matrials,they used to make those "CRT" picture tube materials,not as good as before.
you have to make sure that if you are using external/additional speakers that you keep them away from console. I had a similar problem when I install a surround sound system in by bar and one of the speakers was very close to the TV. A good friend of mine walked in and said "if you want to get rid of that picture problem and save the life of the TV you had better move that speaker." It has to do with the magnets in the speakers.
The vertical output IC LA7847 is failing. It will likely fail permanately and you will have just the horizontal line. The set will require service. Just do not run the set very long in this state. That thin white line can likely burn into the crt phospher and will show all the time thus ruining the glass picture tube...
Your problem is a bad main B+ capacitor. The right way to find this would be with a good ESR type capacitor meter. If you do not have an ESR cap. checker or do not know how to use a cap. checker. a local repair shop should be able to assist you in this repair at a decent price. Let us know what you did to get this set fixed?
