Same plasma, the Samsung PS42C96HD and we’re carrying out the first test again with a second image: display of our homepage for an hour. We are however changing the recovery image: instead of a grey fixed image, we have used a snowy screen. Legend has it that this is the optimal solution for removing a persistent image.

So is a snowy screen more effective?

• During this test the first time, with a fixed grey recovery image, the ghosting remained for 45 minutes.
• With a snowy image instead, the traces disappeared after just 30 minutes.

This is still quite a long time but there is a some improvement of doubtful scientific value! We would need to carry out the test several times to establish our proof more exactly. However we are far from real scientific proof in these tests, just a desire to see whether or not ghosting on plasmas is a thing of the past or not. And we can say it isn’t, at least on this model and in our test conditions. This brings us to our next test: what about testing another plasma?

If you’ve been following the previous episodes, you’ll have noted that manufacturers have been reluctant to lend us their screens for us to put them through the same tests as the PS42C96HD. We have therefore had to chose a victim ourselves. And we have gone for…

...the Panasonic Viera TX-P42G15, another 42 inch plasma but a very recent, pretty high-end model this time.

Same player shoot again, the next installment:

The Panasonic Viera TX-P42G15 subjection to burning, fixed image for an hour!
