Question about LG DU-50PZ60 50 in. Plasma Television
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?
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.

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...
