Screen burn on LCD TVs

[Antani]

Hi everybody,

saturday I went out shopping for a Samsung 32" LCD TV. I had the chance to see one (luckily, before buying) with a noticeable and large screen burn.
This problem was reported as well on these forums on the 40" model. I was then wondering if LCDs of different brands are truly immune from this problem.

Maybe it is a not problem (I don't know how much time with the same static image it took to burn the screen), but I usually play videogames... so, no go for screens with this problem on my side.

Not "burn" - nothing to burn.

Some people have reported, with some makes of LCD panel, some residual image. However it has been explained as being caused by some electrical capacitance. In which case, it will be temporary - electrical change will always leak away to earth in time.

True 'burn' (applies to phosphor-based technologies - plasma and CRT) on the other hand IS permanent, and can only be fixed' by burning the rest of the screen to the same extent (which is what screen 'washers' do).

no burn on my philips LCD, and thats with lots of video games and static Sky logos.

Videogames and Cbeebies were the main reasons for going LCD over Plasma.

It was myself who first mentioned this problem on the forum.

Recently I saw it again at Dixons. The Samsung was obviously on Sky Sports News as while the ad-break was running you could very clearly see the graphs and logos of that channel.

In fact, it looked far worse than most plasma screen-burns look like. Temporary or not, this would straight away put me off Samsung models.

Given also Richard's experience, I think that I will wait for new Philips LCD models. They should be out in Q2/2004 (don't know if only in the US or in Europe as well though), with screen sizes up to 42".

For Nigel: if the residual images are not permanent and due to electrical reasons, they should go away simply unplugging the power cord and waiting for the capacitors to discharge fully, right?

Thanks everybody for your answers.
