Laying down Plasma screens

I am new to plasma technology and have spend a week looking for information on the subject and have found loads of stuff on here. I have searched the forum for the following but have not found any reference.

I returned my Sony rear projection TV to my branch of a national super store as this was a display model and had their logo burnt into the screen. I had given them several chances at a fix, but just replacing the blue gun (they did at first say they would replace all 3) did not totally cure the problem. I spoke to the manager who said I could get a full refund (good service there atleast). I asked about the Plasma screens (hoping he would give me a bit of a discount for all the messing around) well he told me that they had major problems with plasma screens.

I was told that Plasma screens could not be layed down and needed to be kept vertical at all times. If they were laid down then the scrrens were ruined, many people had returned plasma screens saying they were faulty, when questioned they said they had not laid the screens down. I was told that the maufacturers put a micro switch inside the screen which let them know if the screen had been laid down, and if it had the waranty was void.

I was also informed that the shiping boxes had a sensor on them and if the box was moved above a certain angle the sensor would turn black and the screen was no good, so it should not be unpacked.

Now to me this sounded a bit of a fairy tale, I have searched around here and the net but can find no reference to this (I have read the fairy tales about re-fills etc). Does anyone here have any info or comment on this? Thanks in advance.

At least some of this is true. Plasmas can be damaged if layed flat. Not sure about micro-switches in plasmas but my Panny came with a "Tip-Tell" device on the box - it is a flat plastic arrow and if the box is tipped flat then red granules fall out of somewhere and make the arrow turn red.

Although in the wall mount instructions it instructs you to lay it flat on a bit of cloth to attach the rear bracket things - so go figure!

I guess the screen can crack or be damaged if they are moved/transported while layed flat.
You only have to look in the instructions to see that 'laying down' isn't a problem.

Fitting the stand or the input 'cards' calls for the unit to be placed face down.

I don't think that they intend for the unit to be packed or stored in a 'face down' position, hense the "tip and tell".. But for short, controlled periods its not a problem.

Your store manager could get a good job on UK TV - assuming Jackanory is still on the go!!!

The problem with laying the displays down is when in transit - the plasma panel is basically a big piece of flexible glass and if bumped around in the back of a delivery vehicle the glass can 'bottom' out on the electronics within the display and potentially crack.

No manufacturer that I know of has an in built sensor - as other have pointed out you pretty much have to lay every panel down flat at one time or another; video board fitting, wall mount and pedestal stand fitting and theirs no way they service these things when they are stood up on edge.

We have displays in our hire stock that are three and four years old and I would hate to think how many times they have arrived back (in there transit cases) laying down in the back of a van.

The Panny can be layed flat - I have the "4" installed on my bedroom ceiling!

might be a silly question, but err, why??

So that I can watch tv in bed (no neck ache). As I have high ceilings it is also out of the way, and cabling is easy as all the speakers are also in the ceiling.

Unfortunately, this is quite typicaly of many high street stores. Quite simply, the sales people are not sufficently trained on all of the equipment they're selling. To be fair, they're expected to sell TVs, Videos, DVD, mobile phones, and even washing machines! But they should admit if the don't know about something, and never come up with these "stories".

Best to talk with a specialist, who knows something about the products. And to do some of your own research, which can't be beat.

All the best,

I would just like to thank everyone for their information. I have decided to buy one, just need to do a little reasearch on what model is the best value/quality in my buget.

So is it safe to have one in the celling full time?
I quite fancy this idea but thought it was detrimental to the display?

Any chance of a picture?:D
