Speaker image burn on LED? - Canadian TV, Computing and Home Theatre Forums

With older tv's and speakers, I know if speakers too close to the tv you would get a burn on the tv in corner etc.... Does this happen with the new LED tv's nowadays still?

I have a LED (sharp aquos) and sits on my tv stand, the centre speaker is about 4-5 inches right below/in front of it. And my speakers are about 2 feet each side. Will that be ok? I'm not sure if the speakers are 'shielded' or not, they're pioneer the tall stand up thin kind.

No it does not occur on LCD TVs. Your speaker configuration is just fine.

LED refers to the back-lighting method used on LCD TVs.

This was not burn in, it was caused by the speaker magnets affecting the CRT beam (direct view or RPTV). Most center speakers were shielded to preclude this and most TVs had "degaussing" mechanisms (or could be degaussed) so that the TV would (typically) return to normal once the offending speaker was removed. The LF & RF speakers were often not shielded and could cause issues with CRTs if placed too close.

Plasma and LCD are not affected, as mentioned above.
