How can I adjust the contrast w/o contrast control?


Almost all sets have a brightness and contrast (which is often labeled picture instead) in the main customer menu-----look to see if it changes the picture or not.

If issue is the picture is there but somewhat slow to appear or dim the model indicated uses a lamp which may be the real problem...

Screen is all Shades of Red....


You need to remove the front tv panel, search for the screws right behind the screen and speaker area on the sides of tv. Should be four of them, carefully remove the lower have/quarter and you will find a control box, 6 knobs. Try adjusting them to clear the problem, each color has its own knob, be sure to mark their original position befor adjusting. When you find the red adjustment knob, you should be able to turn it down enough so that it doesnt overpower the rest of the colors. Good luck.

Having problem with getting the color and contrast right?


Good Day;
Turn your color down all the way, do you get a good Black and White picture with good black, white and grays? If not your picture tube may be going bad. It can be adjusted sometimes to get a 'better' picture.
If picture is a good B&W; adjust britness level: 50% > contast: > 90/95 % >color: 50%.
Good Luck, big IRISH.

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.

Adjusting visuals on the TV does nothing


This problem may have been coming from the Flyback Transfromer or the Tippler, you have to be a technician to adjust that! if you are, well first thing is to put the TV ON and sent up all the level to max for the brightness & Contrast, then after try to adjust the Flyback screen voltage for hi bright, if it work there, try back now to see if you are getting any control of the menu of brightness & contrast to work! please be careful, there about 28K volts to 35K volts, this can kill anyone... IF YOU ARE NOT A TECHNICIAN PLEASE DO NOT OPEN THIS TV.... RandyXi CriticaL PaniX
