As Graham says, if it's a newish one it should be switchable from PAL to NTSC and should be good for 50Hz and 60Hz supply.... so should be OK.
Most newish TV equipment will operate on either 50Hz or 60Hz frequency, but there are still many that don't. If it doesn't adapt, the different frequency is highly likely to affect the refresh rate and picture quality.
Do some research and discover how the PAL/NTSC 'switch' works if it's not included in the set-up menu.

As joebloggs says, you'll need to pay extra special attention when packaging a flat-screen.
Most need to be shipped upright to minimise the risk that the screen will crack under it's own weigh when bouncing around.

I remember watching a news item on TFC recently that Philippines will be going digital with effect from December 2015. Means analogue TV will no longer work. (No NTSC)
The digital standard will be the Japanese ISDB-T standard for digital television ....

Hopefully some of our Philippine based members will know more.......such as will set-top boxes be provided etc much like our 'switch-over'.
