46" TV + Hefty wallmount + Brick chimney breast = Good

[ElvistheKing]

OK I've got a Samsung WMN5090AE (http://www.empiredirect.co.uk/conten...ke~Samsung.htm) powered wall mount in order to mount a Samsung LE46M87 (http://www.samsung.com/uk/consumer/d...XEU&fullspec=F) telly.

I was planning on mounting on the (exposed brickwork) chimney breast (single layer of bricks) in my house. (NOTE: chimney blocked up, fireplace will be used for AV equipment)

I've just got three quick questions.
a) The Telly weighs about 25Kg and the wall mount another 20-odd, will my chimney be an OK fixing point (the wallmount has 10 fixing screws on a mounting plate 71cm wide by 25.5cm tall)?
b) Should I be aiming to drill the wholes for the rawl plugs into the brick or the mortar between the bricks, I'm guessing the Bricks themselves, especially for the top set of screws which will be under tension.
c) Will the supplied rawl plugs be appropriate for brick work (they are described as being appropriate for concrete and wood) or should I get some different ones, the manual says to use a 9X50 drill bit to drill the rawl plug holes for M6 X 50 screws).


Cheers

I'd go to B&Q and buy the fattest, meatiest fixings you can buy. By far the best, IMO, are metal expansion bolts. These consist of a threaded bolt that sticks out of the brickwork. As you tighten a nut onto the thread, the thread is forced to pull out of the brickwork, as it does this it expands a metal collar which grips the brickwork. Also good are frame fixings.

The existing screws (M6 x 50) supplied have a sort of built in washer arrangement (presumably to spread the onto the mounting plate), would there be a suitable fixing to re-use these or should I just try and get washers for the expansion bolts?
EDIT:
Is this the sort of thing you mean?: http://www.screwfix.com/prods/21997/Fixings/Shield-Anchors/Through-Shield-Anchor-M6-x-5-T25
or is this closer?

Slightly off topic here. I hope your Samsung M87 is fault free!
I am on my 4th. Never known a tv with so many faults.

what's the fault? does it properly die or is there just something minor wrong each time?

Just asking cause I've got one and it's got one little thing which annoys me but not sure if it's a fault or not!

1. Quite a few people are getting a green tint to the picture. Skin tones and grey's are the main noticable areas

2. Freeview judder. if you don't have a very recent of firmware the freeview picture can judder / stutter.

3. Toslink audio dropout. If you have have a surround sound amp connected to your tv from the tv's toslink connection you will get audio drop out. Audio just cuts out for a few seconds. A recent firmware fix should have fixed this.

4. Scart interference. Either or both scarts may be affected. Get wavey lines scrolling down the screen.

5. Earlier sets can't get 1080p over VGA connection.

What are your issues with the set?

None of those!

It might be just the fact that I'm running SD Cable on it.

I've got an Xbox plugged in via the components to give me HD at 720p which is fine, and vga is great from my laptop.

Originally I had it plugged in so I could get the built in freeview, or cable from the digibox, but the built in freeview looked terrible in comparison, now it only has the cable, which looks fine 99% of the time but if you get a white (light sky) background with people just slightly moving they seem to have nasty jpeg compression around them which is very noticeable. I've always put this down to the fact that it's SD and tried explaining that to my wife but she pointed out that on the other TV 28" widescreen CRT which is in the bedroom picking up the same signal it is fine. I have a bit on a DVD which always looks bad, and trying it upstairs and looking as close as possible the picture looks perfect, however on the LCD it has the funny bits round them.

I know SD won't look as good on an LCD as it would on a CRT but I can get to a point where it has almost like a block of colour next to someones face, I can pause the DVD and view it on both TV's. You wouldn't be able to miss the block on the CRT and it's not there, but it is on the LCD so I think it's something the LCD is doing.

I've tried all the settings but can't stop it - doesn't bother me that much - just certain programs it's very noticeable.

Never noticed it on anything running in HD though

make sure 'Movie Plus' is turned off, this can introduce what you describe.

Also, have a look http://www.hdtvtest.co.uk/news/2007/04/22/samsung-le40m86bd-settings/ for setting it up to to get the best picture. It's meant for an HD source but it is a good starting point. Out of the box the M87 looks terrible.
