My mother-in-law's TV, which is not very old, has a problem with the picture. On the top 3 or 4 inches of the set there are always a series of horizontal lines. Is there a way to adjust this? or is the picture going bad??

Neither adjustable nor the picture going bad.
But appears to be a minor problem, chances are that a component in the vertical section of the TV is starting to fail. If you would opt to check it out/fix yourself, most probably would be a capacitor very near the vertical IC, value would be something like 100uF/50V. Though considered a simple job, this would require that you be familiar with electronic components & circuitry, a bit of soldering and use of a DVM.
Should you not be comfortable doing the above, perhaps your best bet would be to seek the services of a qualified tech.
Hope this be of some help/idea. Post back how things turned up or should you need additional information.

Tv is old the tv CRT-(tv tube) it CRT Yoking circuitry not good as before.The tv deguassing coil in not eleminating all the interference of the tv functions anymore.Move the tv unit to the right or to left like about 3 or 4 inches either sides will help for this problems.
you have to take in affect on how old is the tv if you have had it a few years then the screen is going out and will only be a matter of time before it goes all the way out and you will be buying a new one if it not old and its one of the newer flat panels then its the signal that the tv is receiving if its hooked to a digital antena then you only get max of 720 from it on certain channels no matter if the channel or channels are showing hd with out a hd source your tv will not show better then that i have a 42 inch hd flat panel and use a antena and the best i get from my hd broadcast channels certain times will i get true hd like when the news is showing or when one of the series that was filmed in hd is on other then that i only get a 720 picture instead of a 1080 most commercals are not film in 1080 but in 720 max and i dont know why makes no since
lcd or plasma.
are the lines solid or blurred. do they have sharp edges.
You may have a memory problem with the display which can only be repaired by factory trained technicians, or a brave soul willing to find parts on ebay.
Yes, definitely worth fixing. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor (no more than USD4.00 in price) usually gets it working perfectly again. If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.
if it cannot be adjusted then there is a problem in tv.
your problem is in vertical output circuit
Can this be corrected easily ?
or do I need to start looking for a new TV? I love this one and would like to keep it a while longer.
not to look for new tv.you will keep it for longer
that has a picture that recently shifted upward and now cuts off about 1 inch of the top of the picture. Otherwise it functions properly.
your problem is in vertical output circuit
1loose contact in vertical output section
2 capacitor defective in v/output.
it is a common problem.
it is a not a major problem.
if you are not tech person get it done by skilled tech.
hope this will help.
My television has sound but no picture. I can not program the television because I can not see the screen menu. I also have tried to change the antennae but this does nothing to the picture's reception.
Do you have any ideas to correct this problem. There is no warranty.
