Unit has lost verical deflection. Most likely and IC has failed and will need a tech to diagnose and repair.

I had the same problem on a 36" Hitachi TV about 7 years old. After reading comments on this and other pages I went and bought a soldering iron not knowing what I was going to do with it.
After trying to find a loose connection with the power off- with no success, I then tried with the power on. Not the smartest move, but I was able to find the problem.
If you follow the colored wires (blue, green, red, yellow) from the back of the tube they will come together at a connector that plugs into a card at the bottom of the set. That connection was no secure. Since reseting that connection I have had the clearest picture since puchasing the TV new.
I am sure it is obvious that I don't have an electronics background, and I don't have an explaination as to why this worked. I just know it did. I hope this helps someone.

TV screen has a thin horizontal line in center


this will only help until the next time it is out of alignment but if you slap the side of your tv about where the line is it should straighten out but there is no telling how long it will stay straight......My sons tv was doing that and i had a tv when i was young that did it that is what my mom told me to do and what i told my son to do and it works.... the problem is an alignment or conection problem from dust most likely.

Our tv, a Panasonic # CT-36D11E/CT-36D11 only shows a horizontal thin line across the screen. The sound is fine - any ideas? Is it time to replace or could it be repaired cheaply?


Resolder the vertical IC and replace those capacitors near and next to your vertical IC. If the horizontal line still appears, you may have to replace the IC. Thanks for asking and be caredful!

Picture go into a thin line.


You have a thin horizontal line in the center of the TV. You, in this case have vertical IC that has bad grounds. Resolder the vertical IC pins and check the capacitors in the immediate area and replace these caps as necessary. If you still have a horizontal line, you will have to replace the vertical IC. Find a TV tech or someone with electronic experience to do this for you. Should be reasonable to fix. Thanks for asking and Good Luck!

Toshiba 32A14 horizontal line


This symptom is characterized by a thin horizontal line in the middle of the screen. This symptom is caused by the absence of the deflection sawtooth current in the horizontal deflection coil.
The trouble is easily isolated by a continuity test and by checking the most likely defective components such as A)open vertical linearity compensation transformer, B) open capacitor and C) open horizontal deflection coil.
Be sure to decrease the brightness first before trouble-shooting if the line is very bright,as it burn the phosphor screen..

Hope this may help;

Thin Horizontal line through tv blank screen.


Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!
