I just purchased an RCA 50" LED flat screen TV and the screw hole size on the back of the tv is bigger than all the screws that came with the wall mounting kit... anyone else have this problem? How do I mount the brackets when I have no screws that will fit? If I go with a wider screw, it won't fit through the bracket...

SOURCE: no screws for the tv to mount to the bracket

You will 4 m5x18mm and 4 m5x25mm machine screws. That should do the trick..

SOURCE: What is the screw hole size in back of tv

The screw holes are metric. The set is supplied with M5x25 screws to attach the pedestal, so the wall mount screws will be in that same range.

SOURCE: I was trying to wall mount a 32-inch flat screen.

If you get a slightly larger drill threader bit you may be able to rethread the hole to a slightly larger diameter.

Yes it will hold,the wall mount u bought it design for weight of 160 LBS and 50"-60" screen sized right?Just make sure hook up the wall mount on and over a wall area with strong woods beams supports have many fours by fours woods beams lumbers to take off the stress of the holding of the tv by those screws alone of the screen frame screws supports only.

Best way to be sure is call Philips customer service with the model number to get the thread type and length of these--no two sets are the same here---usually most will be available at local hardware stores if Phillips does not sell them(that would be a bit more pricey and take time).
