Ael 16504, If unit performs in same manner when connected to a "Known-Good" pc, then unit may need to have the internal power supply board (SMPS/inverter) checked out by you or qualified monitor technician. What is "date of manufacture" and model number? Have you seen any repair videos at YOUTUBE yet??? Was monitor working good 24 hours ago? Will your pc perform perfectly with a different monitor connected to it? When very "strange" stuff starts to occur with CCFL lcd monitors, the very first place this tech will look is at the SMPS/INVERTER power supply board. Do your research here in the fixya profiles of "budmrtn" "buddymc" 12fixlouie"(me) and at YOUTUBE for video clips of monitor power supply board repair (bad capacitors)
Report what you discover by doing another posting to this response by me. 12fixlouie

There are row and column drivers the operate the pixels on flat screen TVs. A black line either horizontal or vertical indicates a problem with the driver, connector, or the screen itself. It's likely not cost effective to fix being this old.

I have a LG DU50PX10C with a black vertical line


Plasma televisions have anywhere from 24 to 40 drivers that control the individual rows of pixels comprising the screen. Should any of those drivers fail, the screen will display a 2 or 3-inch black vertical line, and probably shift the image to one side or the other. Driver failure is considered a manufacturing defect, and is not preventable by the owner. In some instances the line can be caused by faulty pixel ribbons that run top to bottom, either faulty of just loose in their connectors etc.


Then there are Stuck Pixels, Pixels become "stuck" due a failure to turn on from its standby state. Occasionally, these pixels die in rows, spanning the full height or width of the screen, or be only a few inches long. These "dead" pixels can turn on randomly, or stay a different color other than black. This is an issue caused from the wire filaments inside the panel failing, or an offshoot from a driver failure. Impact to the screen can cause a row to stick as well, even if there is little to no external indication of damage.


However, in most cases, inspection by an engineer is usually necessary to diagnose exactly what has caused the fault, unfortunately this can be an expensive prospect, not to mention the potential for a painful bill for the repair alongside the inspection fee. If your TV is in its warranty, don't hesitate to claim on it.
I hope this helps you, or at least gives you a better idea of what you potentially could be facing. Good Luck.

On start-up, the first screen with the Microsoft flag logo has a matrix of blue square dots (about 1/8" square in size) superimposed over the entire screen. Then, when the desktop appears, about half of...


go into your bios and make sure that video memory shadowing is dissabled, Sounds like a faulty video card or damaged signal cable. I would lean more to the faulty card though, try installing a new one as I would say thats your issue if your getting artifacts on the screen before the OS has fully loaded.

OFC you could try new drivers both for your chipset of *********** board and the graphics card in the interim.

I had a vertical line on my laptop screen


A line on a LCD screen (like a laptop) is caused by a faulty power connection in the screen.

Usually a entire row or column will not activate causing a black line to show. When you closed your laptop, the screen is powered down. When you opened it back up, the screen would be reinitialized and it appears that you lucked out on your issue.

When a row or column fails it is usually a permament failure that can only be fixed by a monitor technician or a screen replacement.

A similar failure can happen that causes black dots to show on the screen. These are burnt out junctions where the rows and columns meet together. The dot is commonly called a pixel.

I am trying to connect an akai dvd player to directv, please help


ruettab,

good day. to connect your any DVD player to any TV screen always remember this color code

from DVD back part:

yellow = video out

red/blue/green( in a row) = component video out ( this can only be used for screen with component video inputs)


Black = digital audio ( rarely use unless)
Red and white (in a row) = Audio output (left and right audio)


where to connect from TV screen.

Locate where A/V INPUTS (audio/video socket) from your TV screen, you can see it either at the BACK/SIDE or somtimes in FRONT of TV screen , having marked as "AV1"AV2"AV3' .

Once you found TV input, you must first have RCA cable (color code cable to connect player to screen) then connect the RCA cable at the back of your DVD player, simply follow color code

RCA yellow marked cable = DVD yellow socket
RCA RED and WHITE marked cable = DVD RED and white socket (second row for your player)

then connect the other end of the RCA cable to TV screen, first select which input where you gonna place the DVD player ( either AV1, Av2 or Av3 if do have multiple inputs)

once decided which INPUT to connect the player.
ex. if you select AV1 as input there would be 3socket on its row (yellow/red/white)

now connect the other end of RCA cable to the screen by following the same color code:

RCA yellow cable = TV screen A/V1 input yellow socket
RCA RED and White = TV screen A/V1 input red and white socket.

cheers,
mark

Vertical black bar down the middle of hitachi plasma tv


Ok if your hitachi TV dies with no power anywhere try this:
Some models have a kill switch under the bottom edge. It's like a gray switch like a small light switch press it back in and voila let there be LIGHT. Saves you at least a $200 trip to repair shop!!
