SOURCE: Horizontal green line appears on screen

my maxent plasma tv has the same problem but it has green and red lines. I found out that hitting the tv from the back works. It used to last a long time but now i have to get up now and then to slap the tv on back with my hands! anyone with a long term solution?

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.

50 inch hitachi ultrvision tv with a thin black line going across..and 2 red,1 green thin lines going vertically tv is 7-8 years old...is this a cheap fix or just get a new tv?

screen connections, not a job for the amiture as it relates to the screen connections on the ribbon, you need to remove screen, then with a large area to work with thats flat remove the screen casing and then remove the boards and then the screen ( paper thin) this is the dangerous part as you can brake the screen or even cut yourself. you need to remove screen and place down on a large flat area (padded flat) and you will see the ribbons on the side of the screen. you need a heat gun or soldering heat gun and heat them up and without moving the alignment push down on them so they stick back down, a roller helps as keeps the air from getting stuck in the seal, after put some heat tape over the connection/s each line relates to a connection on the screen. when refitting put pads that are the right size and shape over the connections before fitting the case, then the problem will not happen again with the screen but like i say its not for the amiture to do as it takes patients to remove screen and you have to keep it level at all times or it will crack.

Red line in the middle of my plasma screen

Hi leprecoce,
One transistor out of millions has failed shorted. That is an unusual failure mode, but not unheard of. The chip can probably be replaced, you might want to check google maps or http://tvrepair.com for a repair shop near you.
Most shops should be able to give you an estimate, I would guess around $300, unless the chip is hard to get.

Screen is black except for thin line in middle of screen

The problem is in the vertical section of the main board. Bad capacitors and maybe the vertical IC. If you are not inclined to be a tech you will have to take it to a shop.. I don't know what they may charge but I normally get $69- $89

I have a sharp aquos 52" with a thin vertical red line in center

If you have a thin line running down the screen, you may be looking at a service issue right off of the bat. Here is a few things I want you to try before calling sharp, 1. Reset the unit from the setup menu
2. Unplug the unit for 2 minutes then plug back in. If that does not work. Take digital pictures of the line and call sharp immediately. Make sure you tell the rep you want to sign up for the aquos advantage program that they have(extends your warranty 3 months free of charge!) because that will get you priority service on with your issue. If they cant resolve that line ,9 times out of 10 they will replace the unit. hope this helps you

Line accross top of the screen with flashing black and white boxes

Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.

Line across screen

I have the same problem with my 42 in. The line started to show up randomly about 1 month after i got my tv. The line isn't a line of dead pixels since when i change the aspect ratio or the tv the line moves up or down. I called sharp about the problem and they said it had something to do with my computer but i don't think that can explain why the problem shows up on all my tv inputs.
