Fan blows no heat


With engine warmed up, feel of heater hoses under hood to see if both are warm (careful don't burn yourself). If they both are warm, flapper door which directs airflow through heater is not working, probably because the actuator is bad or you have a vacuum leak. Check line under hood which goes to vacuum reservoir for vacuum, and check one way valve(check valve). Replace any old soft or cracked vacuum lines.

Picture goes to a single horizontal line.


Your problem is due to failure of the vertical scanning circuits in your TV. This is quite common and is caused by aging components. Generally drying out capacitors
You got to be careful not to leave it on too long when the picture collapses, it will burn a permanent line across the screen.
If you are an electronics expert you can fix it if you get a schematic. If not please don't attempt to reapir it yourself since there is high voltage in side the TV.
The problem may get worse with time.

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...


The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

Black lines in tv


Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.

Red lines across bottom portion of screen


usually strong magnets like those in speakers cause lines on tvs if placed to close to the tv.
so demagnitizing the screen should work .
you may have to take it into a pepair shop to do this.
but if thats not the problem. you moe than likely are seeing a common problem of tv screen burn out. and these new tvs tend to burn out faster than the old ones did.
