Question about Sharp Aquos LC-37G4U 37 in. HD-Ready LCD Television

1 Answer

Thin line across the screen

My older television (19 inch Broksonic) had started taking a long time to come on. Now it only has a thin line across the screen. It's as if someone painted the screen black, then took there finger and ran it horizontally across the screen. It still has audio.

I'm guessing that this is a CRT based TV, not an LCD. That being said, the problem is a failure of the vertical circuit. Usually this is a small flat IC (LA7837 or similar). Try resoldering the pins if you can first. If that fails to resolve the problem, replace the IC. Please be aware that there are potentially dangerous high voltages present even when unplugged.

Keep us posted.

    This happened to an older TV of mine. I cannot tell you how to fix it internally, only what I did to make mine work. It had something to do with the bottom front of the TV. I took a deck of cards and placed it under the front of the TV. I had to adjust until the picture became clear. This worked for a year and a half.

A horizontal thin black line has appeared across screen.


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

42 inch samsung plasma tv black vertical lines


Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric
