This is usually caused by bad earthing, between the units. this gives a phase imbalance.. however, it also maybe Ripple from a faulty power supply, I have seen this before on digital equipment that have leaky capacitors or bad solder joints on them, or a bad diode, and it's letting AC current, become impressed upon the DC current that is needed, any ripple or interference, or bad earthing will cause these and similar symptoms to what you describe.
If you are sure you have good earthing, the house wiring is OK, the cables used between the units is OK, and all earths and things are good and all connected, then it can only be the set itself, and If you have just bought it then this is a manufacturers defect, and as such, it must be replaced, under the consumers guarantee act, Personally i would take it back, and ask for a replacement,or my money back, so i could purchase a suitable one elsewhere. As this is unacceptable from a new, near new set.

Poor Picture Quality on Philips 42PFL7962D


Get the professional, although this won't be an expensive fix... You likely have one or more caps in the vertical circuit that are going bad... A cap acts like a battery in a circuit taking on voltage and releasing it at an even rate. When they go bad their ESR (equivilent series resistance) rises and the cap takes longer to reach it's op temp and work properly...
A tech with an ESR meter will easily find and repair this one...
no other issues only a minor problem..

Slanted picture


Your deflection yoke (a coil around the neck of the picture tube) must have gotten turned. Your can turn the picture upside down by rotating this coil. If your set is in warranty, you should return it. When this "yoke" is adjusted the color is affected too. If you try this yourself you'd void the warranty and mess up your color. Stargazer
