    I've been an A/V service tech for fourty-five years. Worked on the USAF's first digital satellite secure comjunications equipment back in the '60s. I'm just new to LCD technology. Can you suggest any good general purpose tech manuals for LCD tech? Thanks And BE Blessed!!! IHS Ted Leber

There are several things that can cause it. You are best to have an expert technician come in and take some test on it in order to determine if it is from vertical blanking failure or something else. It is not easy to fix this yourself, if you have no experience, because there are a lot of parts that have to be removed before you can reach the components. It could be as simple as a loose connector ribbon or a bust capacitor, but it could also be more complicated. Hence, in my honest opinion, better get a qualified technician.

Hope that helps!

The vertical line could be cause by the screen driver board, it could also have a loose or oxidaze contact where the main board connects to the screen driver/buffer board.
How old is your LCD?

This line would either indicate a horizontal problem cropping up or a power supply problem

I would suggest getting a service tech to look at it to determine where your problem is coming from but most likely it will be the power supply /deflection board that is the problem but I can't know for sure, it will have to be checked.

A lot of sets have had damages after a long hot summer a/c flipping off and on and current demand being peeked from the utilities storms or quick power loss off and on can cause problems like this to occur

Please let me know if you have any other questions, thanks

Vertical blue stripe on my Sony KDL-40S4100


Was the telvision impacted? Usually a Blue line on various tv sets such as Sharp and Sony can also indicate a firmware upgrade being needed. Try that first, as to a panel if this is a panel we have in stock cost could be between $200-400 for the part that part cost from Sony coulb be double if you need to purchase new. Call or reference us if you need TV repair in Colorado 6_2_2012_7_06_05_pm.jpg

Red vertical line down right side of the screen


hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use


On al the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black lne down the screen. Seeing as the tv is new I would get the warrantee repair on it. There is a possibility that there is a problem with the screen itself but more than likely its the boards.

Vertical line


Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.
