Panasonic Viera TC-P50VT25 stand assembly screws -
Hello, Thank you for letting me join this forum!
I've just obtained a Viera TC-P50VT25 but it did not come with the stand. I found a used one but it does not come with the screws that attach the stem of the stand to the back of the TV and the screws that attach the stem to the base. would anyone out there know how I could get them or can you tell me the size and I may be able to find ones similar at a hardware store. Any information would be greatly appreciated.
