Failure of the horzontal linerity coil, possible dry soldering on the board of the components- resistors and capcitors- in the horizontal coil circuit . Also failure of the deflection coil- YOKE- in the crt. So check the coils and the circuit around this section as the rest of circuit seems OK.

Horizontal line in RCT TV because vertical deflection not working. IC vertical can cause this problem. Check Vertical Vcc from FBT ( generaly 16 - 45 v dc) , check input vertical from IC micom or video processor is it OK or NG. Check conection vert deflection too, is it connected or not.
Check R fuse on Vcc , diodes an capacitors between voltage line and ground. Short component (Diode, Cap ) can cause this problem.
Good luck.

    I am having similar problem with CRT, after three attempt of repairing the tv worked just for few hours and again it gives me horizontal line. On each repair attempt few capacitors and one IC was replaced. Do I need to change the yoke as it was suggested last time by mechanic or go for new TV.

We have a 27" MTS Stereo color TV. There are white horizontal lines at the top of the screen. We do have a DVR with Direct TV. How do we fix?


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.

INEED NO. OF OUTPUT HORIZONTAL LINE TRANSISTOR


If you mean 'flyback' or 'horizontal output transformer' and have the part number available, try one of the sources here:
Flyback links 
If you do not have the number you may have to search Viewsonic's website to loacte it.
Warning; the number of suppliers for CRT monitor parts is shrinking rapidly, my best supplier, ICM in California is long gone.

CRT TV picture keeps getting horizontal line & loud cracking nois


the horizontal section is near collapse, the lines indicate a sort or leak. Soon, the set will go black. Shut off as repair will be cheaper now! Needs professional repair as High voltage section is dangerous.. Unplug to be safe!

After a household power blips during bad weather, we have horizontal lines ....


Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .
