A lot of new tvs breakdown in the first 6 months to 18 months.
I'am interested to know how many of these tvs are wall mounted. Does wall mounting put more strain on the tv than free standing, or is the breakdown numbers equal between the two. Thanks for any feed back in advance.

Wall mounting has no effect at all - however, you are also incorrect that a 'lot' of new TV's break down in the first 6 to 18 months. Small numbers of sets do, with most of them been the cheap junk sets.
So am I right in thinking that the air vents at the back and top of these tvs can function properly at 1 to 2 cm from the wall, the reason I ask is in my panny manual it says to allow 10 cm air flow, back and top. Also gravity pulling a 20kg tv from the wall must put so strain on the frame and screen.
Instructions usually specify the air flow required around the set, and you should follow then - generally the requirement is for below and above, in order to allow good convection flow.
There's no more strain on the screen than otherwise, as the chassis is supported (just as normal) and the screen hangs on the chassis (so it's no different at all). If anything the chassis is BETTER supported when wall mounted.
Which was why I replied - I see large numbers of sets per year, and (as I said) wall mounting has no effect at all on reliability.
Thats your opinion Nigel, I would be nice to here from people first hand.
That's a 'statistic', based on a fairly large sample size - and in actual fact a far higher sample size than you might imagine, as other engineers (in the UK and elsewhere) find just the same.
Why? Nigel's information will be better than hundreds of individual posters giving their thoughts as he deals with TV's all of the time.
Do you just want someone to agree with you?
Does Nigel know wether the TV he's repairing was wallmounted or freestanding, eg, panasonic make out there 2010 models plasma are fab, but acording to the owners of theses TVs they have floating blacks and fading blacks over time, should we take panasonics word that these tv are working within spec, or the owners word of the floating blacks, thats why I asked for owners who have had a repair wether the Tv was wall mounted or freestanding.
Yes, freestanding sets come in with an attached pedestal mount, wall mounted ones have that missing, and brackets mounted to the set. It's not rocket science!
There's also the added 'hint' when you have to take it off the wall.
thanks Nigel, now maybe you could tell me the amount of tvs you have repaired that were wall mounted against the ones that were free standing.
Whilst you are awaiting Nigel's response to your question, I'd say of all the flat panels that we see in our workshop for repair, only 5-10% of them are wall mounted.
It's not something you ever bother counting - but I would assume similar to MIKEFL0, probably 5% or so?
I don't think anywhere near 10% of sets sold are wall mounted.
On a quick count at the moment, out of 15 sets in the workshop, only one is wall mounted - but that's far too small a sample to be significant.
Mostly there won't be any wall mounted sets in for repair in any one week, but occasionally you may get two a week.

But perfectly true
The numbers of breakdowns can never be equal between wall or table mounted sets because far far more are table mounted, Statistically speaking far more table mounted sets should breakdown than wall mounted simply because of their greater number. However what you are I think asking about is what is the breakdown ratio is of wall compared to table mounting.
If a ratio of 50% of wall mounted sets breakdown within six months and only 10% of table sets breakdown then it is obvious not to go with wall mounting, this is of course independent of numbers
I've seen one set fitted like that, it was a really nice job - two chrome poles came down through the ceiling, with the TV fitted to a metal plate fastened to them.
Yes, Nigel that is the sort of thing....It all looks really nice and of course all wiring is run through the pole (just one in their case). The speakers all emanate from the ceiling as well...All in all, a very tidy set up.
Wouldn't work in mine unfortunately but ideal for her house layout.
