Hi Sharon,
Here are some solution that may help you fixing the problem. You might need a help from guys that can perform steps below.
I'm assuming that your outlet is live.1.Power
cord - check the cord it
might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-
sometimes the fuse fail because of the power
surge, replacing with new one will cure the problem, If this is the case
I've advice you to use surge protector/AVR (Automatic Voltage Regulator).
However if the fuse blew again this is an indication that you have a shorted parts on the power supply, you may visit the
link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and
still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact on the board, don't attempt to touch
anything because there somefatal components
stored electricity enough to hurt you with a simple mistake only.
The next steps should be done by an expert or qualified technician
because isolating the problem on the power supply is quite technical.
Also check if your unit is under warranty before opening the back
panel, it will void the warranty. Avail it because the manufacturer of your
unit will fix it for free or a little charge only.
Hope it may help you.
Thanks for using fixya.

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors.
Many electronics companies were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's
called: Fixing the Philips Turns/shuts off on its own problem.
Hope this helps and Good luck.
