A horizontal or vertical line on the screen They can be caused by a loose connection, a failed capacitor, or a burned-out coil. An expert can only do the replacement. 
Poor quality picture appearing to be bent The internal convergent circuits could be faulty due to bad connections, faulty fuses or resistors. An expert can only fix this problem.
No sound at all or poor quality sound It could be caused by faulty speakers, amplifier issues due to low supply voltage, or faulty wiring. An expert will be able to fix this issue.
Shadows at the edge of the screen If this happens, there's likely a magnetic field near your TV set, failure in the TV's thermistor, or the cathode ray tube needs degaussing. If the magnetic issue is not the cause, you will need a technician's help.
The smell of burning and a crackling sound It is caused by the failure of the cathode ray tube. If you experience this, switch off your TV immediately and get an expert's help. 

Flat screens TVs
We don't recommend you attempt any internal repairs on flat-screen TVs like in CRT TVs; an expert should do them. Flat-screen TVs have different types of screens, LCD (liquid crystal display), PDP (plasma display panel), and LED (light-emitting diode). Here are tips you should know about flat screens TV repairs. 

Flat-screen TV issues Flat-screen TV repair measures
TV turning on and off intermittently This could happen because of unwanted signals being received; try covering the sensor at the front of the TV to see if it happens; if it happens, find the obstacle and move it away. Unplug the TV and plug it back to see if the problem is still there. Remote batteries can also cause this, changing them more often.
TV set on but no sound The first action to check is to check the TV settings menu; someone could have accidentally changed the sound settings. If the settings are okay, you may need to call an expert. 
Having sound but no picture You can fix this by attempting to increase the brightness and contrast. Also, check if the wires are plugged in properly in the sockets. Call for help if the fixes don't work. 
Color patches on the screen Magnets can cause it if near your TV; check that there are no magnetic devices near the TV set. You can also try slapping the patch slightly with your hand; if you notice any rings of colors appear with waves, most likely the screen is damaged.
Interruption of images by poor reception Poor reception can cause interruption with TV images and ghosting; ensuring you have a high-quality lifted aerial will help get an improved reception. 
Discolored images or images not moving. Discolored images can be solved by checking the picture settings and ensuring the brightness, contrast, and color saturation are okay. Also, check the TV wires to make sure they are not loose.
Black bars on the screen Compatibility issues can cause this, i.e., whatever you are watching is made to be monitored on a different display. The only way out of this is to use a compatible device.

There were days when the only solution to a broken TV would be to have it repaired. TVs were so expensive that buying a new one would not be an option. But times have changed; TVs now come with warrants for a quick replacement of a defective one and can also be bought cheaply. 

Weighing options on whether to repair your TV or get a new one, you may have to consider several factors like the kind of repair your TV needs, how much the repair will cost, how old the TV is, etc. You might also need to check how much a new TV costs and compare it with the repair charges, and you will have an answer as to whether you need to repair or get yourself a new TV set. 

The most expensive TV repair is a cracked screen, which may cost the same price as a new TV.
