I bought a Toshiba plasma TV nearly five years ago and recently MediaCorp's channel logo got burnt in on the top right-hand corner of my TV screen.

I e-mailed MediaCorp to suggest that it moves the logos around instead of having them stay in one place for a prolonged period of time.

MediaCorp advised me to buy an LCD TV instead. I do not know whether LCD TVs will also face the same problem.

I wrote to Toshiba and it said all brands would suffer burn-in if any logo is displayed for too long.

How long a logo stayed in one spot is beyond our control unless I switch channels every couple of minutes.

I took some timings and found that the channel logo lasted about eight minutes before a commercial came on.

Fortunately for me, I had purchased an extended warranty or else I would have no recourse.

Would the Media Development Authority or Case care to comment on burn-in and what can be done to alleviate this problem?
