Question about Sharp LC60LE835U AQUOS Quattron 60" 3D LCD/LED HDTV LC-60LE835U

1 Answer

Vertical lines showing up after being on for awhile

Some time after being powered on with a signal (cable or player), the screen begins getting vertical line blocks. The screen seems like it has 4 horizontal blocks, and each block begins flickering (well, its either messed up for a few seconds or normal for a few) between the normal image and vertical lines. After several seconds (10-15 usually), the screen stops flickering and just has vertical lines. If the TV is powered off for a few minutes and turned back on, the image is fine for abit. Doesn't seem to have a set time before messing up. This problem did occur several months ago one evening, but I powered it off for about 20 hrs, dusted off the externals and back openings and the problem never came up again this week.

Eh, I can't be too sure, but it sounds like it's either a heat issue, a signal issue, or a backlight issue. Either way, if it's still under warranty I'd send it in.

SOURCE: green vertical line on the right side of screen

Warranty still alive?
Hope so; the problem could be an expensive one.

The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.

I would be talking to Sharp - this shouldn't happen in 6-7 months of use.

Permanent Vertical Line on my Sony Bravia 46 inch LCD TV


What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

Sansa E200 screen stuck scribbly black vertical lines


When it is on, holding the power button in for 5 or more seconds hard resets the device. Give that a try. If not. it's possible it's been bounced one too many times and needs the LCD cable re-connected or the controller is bad for the LCD.

Wavy lines


Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.

Samsung TV stopped displaying picture


No picture but sound can mainly be of two problems, most of the times it is caused by a faulty vertical deflection ic, you can diagnose this by slightly increasing the screen voltage by turning the screen control on the LOT, a horizontal line will appear if the vertical ic is shot, and the other problem is the CRT base, but this is less common for shot base won't go off at once, it will show picture faded in the beginning. Now another problem could be the horizontal output transistor, if the tv has a high power sound output, the sound power supply will come from smps itself instead of from LOT, check that too, to confirm this, check if the CRT filament is glowing. Good luck.
