Infocus DP8400x blue hazey line

Infocus DP8400x has blue hazey line running vertically along left side of the screen. Blue is darker near the bottom and becomes lighter as it moves up the screen. Is this repairable? It began showing up a day or two ago.

This discoloration is the begining of the lcd panel being thermal damaged. this happens when the projector is being used for a long period of time and then being shut off using the switch on the rear of the projector instead of the on/off on top or the remote. to fix it it will have to be replaced. very expensive major repair.

    It's never been turned off in that method... always turned off via power button and the fan keeps running. Could it be any other thing?

    based on you being 100% sure this is a DP8400X and without being personally able to see the discoloration,I can only guess based on what you've said is wrong-- it can only be 3 things---lcd is starting to have thermal damage which is a major repair, or somehow the factory settings have been changed in the HIDDEN SERVICE MENU for ghosting etc,which requires a technician to use a test screen to realign, or something has made it's way into the lcd panels-- some kind of dust particle,hair or something which would require removing the 2 front bezels and the top and then blowing air down into the panels to get the particles out.

    You can also remove the lens and make sure nothing is trapped behind it.

VIZIO P42hd PS42a plasma Picture has two vertical lines (one red/orange, one blue) going down the right-hand side of the screen. Lines are clearly visible


The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

40 inch lcd blue line vertical


The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

Blue Vertical Line


It is sounding like when the laptop is turned on and heats up a bit, the line appears? Sounds like one of the panels is going bad or atleast has developed a problem. below are some tricks you can try to lessen the annoyance of the line. Dual-Scan STN displays are composed of 2 panels behind a single protective panel or screen. Because you are looking through the protective screen the display appears to be one large panel even though it is not. There is a physical separation line (gap) at the point where the two panels meet. When the computer is on and being viewed it is not unusual to see the visible separation line with the Dual-Scan STN displays. The line, actually the fine gap between the display panels, appears because the color and light pixels cannot run along the very outside edges of the panels. This line (gap) between the panels can be seen as a fine gray line and is most noticeable when viewing on a screen with a white or light background. Note the line may not be as noticeable when the screen is displaying certain colors or darker backgrounds. SUGGESTIONS: It is not possible to completely eliminate the line but there are some things you can try to reduce it's visibility. 1) Lower the display brightness/contrast. The brighter the backlight the more noticeable the line. 2) Use Wallpapers and Screen savers that use darker colors. 3) In the Control Panel/Display applet under appearance try different combinations of color schemes for your Window and Background choice Let me know what happens. Good Luck, Tim
