Some say 100, some say 200. I did 200 to be on the safe side. Yes, you can use the D-Nice slides or the Evangelo set I just posted a link to. I'm not sure if any of this is necessary - but it can do no harm, the slides are free, and the process is easy to run, so I took the decision to play safe and ran my set for 200 hours - all the time I wasn't watching any actual content on the TV, the slides were running, day and night until I had clocked up about 200 hours. WRT to actual content, just be sure not to leave logos or black bars on all the time, at least until the panel is broken in.
EDIT: here's the link again to the slide set I used:
I ran D-Nice's slides for a bit over 100 hours. But after i had problems with Image Retention when i paused the menu of a game i was playing. Even though i only paused it for a very short time, i even feared it was burn-in.
Would i benefit from running the Evangelo's slides for a certain amount of time and if so how long? Since i've already done the inital 100 hours.
And if im getting Image Retention easily does that mean the TV hasn't been broken in properly?
Appreciate the reply.
You can by all means run the Evangelo slides, but I suspect they do a very similar job to the ones you have already used from D-Nice. The slides won't get rid of any existing IR - they are not designed to do that. If you have some IR, then run the screen from the Panny menu that 'wipes' it. I can't tell you where it is on your unit because ours in Europe have slightly different menus (and specs) but it is in there somewhere - probably under Picture Controls.
I'd doubt very much that you'd have burn-in on a modern screen. There have been varying reports of Image Retention on these screens. I don't have any at all, others report they have some sometimes but it soon fades. If yours does not fade fairly soon, then there might be a problem but I am not sufficiently qualified to comment there - others may chime in. Meantime, run the IR 'wipe' facility and see if it solves the problem. Another way to do it is to tune the TV to a non-station so you get white 'static' all over it and leave it like that for an hour or so.
