    Hi Guys, long time member but haven't been around for a while .... anyway, I've gone & bit the bullet & purchased an LG 55EC930v OLED TV, which will replace my ageing Pioneer PDP436XDE, which has served me well. Currently, the pio is on the wall above the fireplace, & I built the chimney beast out so that the screen would sit nicely "in" the wall, but now I find, although the pio is 43" & the new LG is 55, that the hole in the wall where the TV sits is about 3cm too big, & so the new set won't look like its sitting against the wall, but rather, in a hole in the wall, which will sook rubbish. So what I'm hoping to do is fill in the 2 sides & the top by about 10cm of plasterboard, but was wondering how to stop the plaster cracking around the existing metal edging?? Would a filler do, or will I need to take out the edges first?? Thanks in advance for any advice

    BTW, Those last 2 photos are with the TV pulled out, showing the "cut out" in the wall.

    I'd pull the beading off first as that'll allow you to blend the two in together better.

    Cracks are caused by movement, so as long as you make every effort to securely fix the two together, you shouldn't get any cracks.

    If you fix a bit of timber behind it, to create a lip, you can then fix new plasterboard to this lip and re finish it with some more beading.

    Thank you very much for replying @Geps, you kinda confirmed what I had in mind ..... My only concern is removing the beading, should I score around the outside of the beaded area to prevent the plaster damaging further up the wall??

    Again, thank you for you're advice

    I doubt you'll need to..but as long as you don't slip, it can't hurt.

    Well, Its been a while since I last posted in here, so as everything is complete I thought I'd post a few photo's of how this project progressed. I'm very pleased with the results:thumbsup:

    These first pics are of reducing the size of the hole in the false chimney breast we built a few years ago to accommodate my Pioneer plasma & Kef Ci9000ace, the Pio has now been replaced with an LG 55ec930v, & due to the curve I needed to reduce the hole, as it was made very visible & looked unsightly.
