LG Plasma TV showing purple haze on white screen

The Tv has a great picture except when a pure white screen comes up. The TV shows a hazy purple-ish white color over about half of the screen, darker in some spots and looks blotchy. Can this be fixed?

Thank you!

Make sure that the color control level is set to the default or 50% to start with. This should be in the Video menu.

The colour for the tuner and for the encoded base-band video uses a circuit area called the colour demodulator. It is possible that this cirucuit area has failed and needs servicing.

SOURCE: Philips Plasma 42" - constant purple haze

all philips plasma sets have issues with overheating heatsinks.
any heatsink that burns you upon contact is a recipe for disaster.

using cooling fans on these overheating parts will generally provide
great reliability in the long rung.

Unfortunately, this sounds like a problem with your TV's lamp. They are not cheap to fix. Search Ebay for a new lamp and get someone to install it for you. These Mitsubishis have a design flaw that make the lamps burn out quickly.
One thing that will PREVENT this problem is making sure that the TV's vents are clean.

If the picture os goint to lines right from the midpoint downward then most likely you will have to replace the lower y-buffer board part number BN96-02027A. The board is mounted on the left side of the plasma panel when you take the back off. The upper y-buffer board sounds like it is failing as well and this was a very common issue on the older Samsung plasmas. The part number for it is BN96-02026A. Please take a moment and rate my answer. Thanks...

Blurry, purple bar across middle of plasma tv screen


Plasma screens are extremely susceptible to getting broken from any impacts to the face of the screen. What you are describing sound very much like distorted or dead pixels. It may not be a fixable issue, you may have to replace the entire unit or live with the purple bar. The reason you don't notice it as much when the screen is dark is because purple is on the darker end of the spectrum, and will be most visible in contrast to lighter ad brighter colors.

Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

The buzzing is normal thing, because white screen requires most power and your chopper works at its max. The sound comes from inductance coils and transformer because of old isolation and glue which shouldnt make any problems.

Rainbow static on Plasma Tv


The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.

Hi; your TV has burn screen or traces.it comes from one image left on the screen for too long, it can get burned into the screen, making it visible at all times. You can actually eliminate most screen burns with the use of a PC computer and a black and white screen saver. This trick eliminates screen burn after a period of several minutes because the black and white screens flash quickly, removing all traces of color from the screen. This will eventually eliminate any burned images on the LCD screen. you can do it by creating a DVD picture slide with only black and white image. you can use a computer to make DVD picture slide first go to paint brush and draw only white then save as white.jpg. second burn it into nero or other dvd burner third play it to your DVD player connected to you LCD TV.it has to be played in full screen let the white image display on your HDTV for several hours or even overnight. It should remove any burned-in images or ghosts. hope this help...............
thanks....

Double picture on start up


Hi,
It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the coursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of syncs.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.
Good luck...

Purple and white distorted fuzzy lines running up and down and side to side on tv


I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.
