The fault is a failure of the deflection circuit and since you have not specified whether it is a vertical or an horizontal line the section failed will be related to the position of the line.
If horzontal the vertical IC or the section related is faulty and if Vertical the horizontal section., Now this can be the deflection IC, teh deflection coils or even discrete components like capacitors or resisitors in this section which will require a signal trace with a voltage test before the absence of the sync pulses are confirmed and the section identified.
I request not to change the IC unless it is proved but you can solder the vertical IC or the section concerned -- if there is dry soldering.

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!

Set only has a thin line across,but sound is still there Is this something that I can repair myself ? I dont know much... 1 Solution


This is a problem with the vertical circuit. It can be as simple as poor solder connections at the vertical IC or a defective IC. Look for a small flat IC attached to a heatsink with about 11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that does not resolve the problem, replace the IC. Please note that there are potentially dangerous high voltages present inside the set even when unplugged.

Keep us posted as there may be other components that need to be replaced. If so, the symptoms will change. Report them here and we'll provide additional details.

Thanks,

JVC Interiart 32" Digital TV. No longer turns on. Has a thin horizontal line across screen when TV is on. No picture.


The thin line indicates that there is no vertical. This is usually controlled by a single IC (vertical IC). Look for a small flat IC attached to a heat sink with 9-14 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC with a new one.
Keep us posted.

My mitsubishi CS-35405


This condition can be easily fix by replacing and IC that is the vertical amplifier.
The number is something like LA7835 or LA7836, this IC is mounted on a heatsink.
Do a search in google for it.
