Plasma TV Longevity List of Categories

- I have read that still pictures over a long period of time should be avoided when using a plasma tv because a permanent after-image may remain on the screen. Will a plasma tv be affected by the logos that some channels display permanently on a corner of the screen or by the bottom lines that are used by some news channels to provide news briefs?
- Is it true that the plasma TV only last for a few yeras, the screen with the time, the colors fade?
- I heard from a contact that works for a plasma TV manufacturer that plasma TVs should not be tilted forward as this is bad for the display - Apparently, the display is glued to whatever is behind it, and tilting the TV forward can weaken the glue/bond (due to the effect of gravity). Is this true? I'd like to buy a fully articulated wall mount but don't want to damage the TV.
- We have 4 plasma displays in an office environment. Is it better to put into standby mode at night or completely power them off? Which would best prolong the life of the units?
- You've commented elsewhere in the FAQ on the effect gravity can have on the glass and pixel phosphor coating when a plasma TV is shipped, stored or mounted horizontally. What concerns are there for storing plasmas on the short end, and at a small angle from vertical? An example would be 20 degrees with the glass facing up.
- What's the minimum amount of space that generally needs to be left behind a plasma TV in order to allow for optimum ventilation?
- Do Analoge Signals Damage Plasma TVs over time??? I have an ellitest friend who says that thats why he didn't get one...
- I've just purchased a Samsung SPN4235 to go in a 50' Ocean Sport Fishing boat. We will be traveling thoughout the Islands. Do you think the motion of the sea (pitch/roll) will have any adverse effects on the TV...thanks
- I am an employee of John Deere. We are looking at implementing animations and slide shows for instruction on our shop floors. These screens will be in very harsh environments. They will have to withstand welding, dust, dirt, etc. We are most concerned with magnetism from the welder effecting the screen. Currently we have small computer monitors that display the images, however we need a much larger screen. What specification do we need to be concerned with for the magnetism? Do any brands make industrial type products? What would you recommend for this purpose? In the past we have shielded the computer screens with a metal box, would we need to do this with the Plasma screens as well? Thanks, Jeni Krebill
- Our company attends many tradeshows and rents 42" plazma screens (not TVs) at the shows. I am considering buying one but am not sure how long it will last and if it's likely to break upon shipping.

The logos would still apply as a still image. However most newer plasmas employ pixel rotating to prevent burn in. Commercial breaks also helps to prevent image retention. I would not be concerned with burn in on the newer plasmas with this technology.

That is not true, please read the following article: http://www.plasmatvbuyingguide.com/plasmatvreviews/plasmatv-life.html

Looking at your question from an engineering point of view, I can understand what your friend is stating. Gravity is always applying a downward force on the display. I have never opened up a unit to see how it is constructed. There are two panels of glass sandwiched together with electronics attached to the back. How the forces are distributed inside, I can not comment. I will state that at 20 degrees of tilt, the most typically found on a tilt or articulating mount, will not vary the downward force very much. I have not heard of a plasma becoming defective while being at an angle of 20 degrees or less for an extended period of time.

The plasmas are designed to remain in standby mode drawing minimal power from 5W-8W. I would not be concerned about leaving them in standby mode overnight.

I would make all attempts to store it at 90 degrees. I would not recommend storing the unit at 20 degrees.

- What's the minimum amount of space that generally needs to be left behind a plasma TV in order to allow for optimum ventilation?
The amount of space required will vary for different plasmas. I would read through the owner's manual for their specific guidelines. If there is no space behind the unit (wall installation), you will want to have open space around all sides of the unit. I would suggest a minimum of four inches.

- Do Analoge Signals Damage Plasma TVs over time??? I have an ellitest friend who says that thats why he didn't get one...
Analog signals will not damage a plasma. I would stretch a 4:3 aspect ratio image to 16:9 to help prevent from any burn in on the display.

Congratulations on your purchase and enjoy sailing the seas worry free. Most damage to electronics and plasmas will come from an abrupt jarring impact type force. Unless you are fishing on really rough waters and hugh swells, I would not expect the pitching and rolling to impact the lifespan of the plasma.

Plasmas are not affected by EMI like a standard crt based display. I would worry more about the environment conditions, dust and heat can easily impact the lifespan of a plasma. I suggest using an enclosure that will protect the unit from dust and allow heat ventilation. I would also suggest researching the plasmas from NEC, Panasonic and Pioneer.

You can purchase a plasma shipping case to protect the plasma while transporting it between shows. You can expect a plasma to last approximately 60,000 hours total and about 30,000 hour to reach half of its brightness.
