You don't say what plasma you're asking about, but it sounds like a Pioneer. If so, power mode 1 is generally recommended on this forum. Pioneer recommends mode 2, but most people find it too dark. Give it a try, you never know.
Always leave the unit in standby, unless youâ€™re concerned about lightning strikes, or possibly are away for a long period of time. At a minimum, I would also recommend a good surge protector for all your equipment and possibly even a power conditioner. The merits of power conditioners are debated a lot on this forum. Some are in favour, some are not. I have one myself and it gives me some peace of mind.
