Colour is not normal, sometimes the picture is too dark, football pitches bright green, peoples faces very orange.


that would be a failing tcon board on the back of the screen.you would need to replace this part but they are available on ebay the part number is on the tcon board. match the numbers a version number to get the matching board for the screen. tcon board is the board were the main wire cluster goes to the screen board this is the tcon board.

Green line down left side and geen snow


Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.

it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.

Black/Green Distortion - Picture Quality - Wharfedale


This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

Try # 2... Green Fog


The green gun in your picture tube is set a little too high. If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT. BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS I hope this may help you.AGAIN BE CAREFUL!! Stargazer
