Is a Media box OK upside down?

    Hi all
    I recently purchased a Hitachi 32pd5300 for the bedroom and as some of you might know, it comes with a media box.
    For reasons that are far too long winded I have to have the Media box upside down.
    Do you think this will do it any harm? Seems OK so far.

    the only problem is that the picture will be upside down, so you will have to turn the plasma upside down as well, but be carefull that the pixels don't escape out the top :devil: :devil: :devil:

    The ventilation holes are on the top of the box (assuming it's the same box as the 42PD5300) so if this ends up resting on a shelf, you may have problems with overheating.

    The box gets bloomin' warm the right way up - I wouldn't want to risk it without a fan.

    Although the box is upside down (in a well ventilated cabinet), it does sit at around a 45 degree angle up from the shelf as it's actually too wide to fit lying down flat. So it's well ventilated all around.
    Heat dissipation seems Ok, just the fact that it's upside down is a little worrying.

    This might be total rubbish, but I thought heat rises. Hence the vents on the top of the box...so if the box is upside down surely the heat isn't esacaping as well as it should.

    I'll get me coat...

    Will it not stand on its side?

    As baker says, heat rises and the design internally is allowing for upward facing heatsinks wherever excess heat is generated. This heat then has a path to escape through the upward facing vents. If this is upside down, or even on its side then that heat isn't rising evenly accross the heatsink - it's only coming off the top facing fins and not likely toward the vents either. So you might get away with it in the short term if the overall ventilation is good, but I've learned the hard way it's not worth the risk.

    The reason I asked about standing it on its side is that the Pioneer media box can be stood on one end. I thought it might be the same for this one?

    Now I'm scared!
    Good point Liam and dsbaker. Forgot that the heat needs to rise (even though there are ventilation hole underneath the box, the heat will probably be blocked from escaping by the circuit board).
    I don't think I'll risk the current set up as it is. Even though the box is cool I'd never have total peace of mind.
    A bit of rearranging later then!
    Cheers everyone.

    Heat sinks that are designed to be used flat are nowhere near as effective when used vertically. The control box on my TV is on a shelf of its own with another shelf about 1.5" above it, and the underside of that shelf gets rather warm, because the control box does seem to push out a lot of heat.
