I work for a charity supporting adults with learning disabilites to live in their own homes.
One of our Service Users is purchasing a 42" plasma TV but due to his needs it must be boxed in.
Does anyone know what risks this could cause?

Overheating could be an issue, I would have thought - best ask the manufacturer.

I would have thought overheating too.
Would it be possible to have ventilation holes / slits cut into the box, or a mesh used at the top, and / or an extractor fan to remove the heat such as used in a PC tower?

Thank you for your prompt reponses, I've thought of overheating and suggested ventilation holes but was wondering if any gases are given off from plasma screens when enclosed?

I wouldn't have thought so, otherwise there would (should?) be a warning about using them in small rooms with poor ventilation!

The act of enclosing electrical equipment will as already pointed out, likely lead to an increase in temperature.
Some modern materials will discharge fumes when heated, so although not specifically mentioned as warranting "well ventilated" conditions, the manufacturer will have made those decisions not expecting you to enclose the equipment.
They are likely to be low volume, but...
So yes, discuss with a specialist.

I believe the screen itself is hot to the touch on Plasma screens - perhaps part of the reason for boxing it in?
The manufacturer is really the only competent source for any minimum distance requirements for fixed objects (such as a perspex sheet?) and ventilation needs. It may not be possible to do what you propose.
Over time, any secondary screen will need to be dismantled for periodic cleaning of the inside face - a potential hazard to the unwary.
A 42" screen - wow! that must be some size of house. I'd need to sit at the back of my kitchen to comfortably view a screen that size in my lounge. Is this a wise purchase?

Why must the screen be boxed in? If it is to prevent access to the power and signal leads most, if not all, plasmas have the leads near the bottom of the screen which would mean that only the bottom of the screen would need to be enclosed.
I assume that it will be wall mounted and if so most wall brackets are designed to allow sufficient air flow.
I personally have a 42” plasma in my home and I have not experienced any excessive heat on the actual screen but that does not say it does not happen.
If the requirement is to eliminate the chance of damaging the screen through contact the screen itself could be protected from the sides leaving the top and bottom free for air to circulate.
Hope this helps
Garry
