Question about Flat Panel Televisions
I have a 46" flat screen TV and the picture is smaller than the screen about 10" on each side. I don't know how to fix it.

I bought a plasma Philips 42 inch model number 42PF7320A/37 also 18 months ago. The exact same thing is happened to us. The screen would go black every since we brought the tv after about an hour of watching it. Then the other day it went black and never came back. The red light in front is blinking and they are saying we need service!!!!!! A $2000 TV lasting 18 months. I am trying to get Philips to be accountable, I am very upset with this product.

I have this problem with my 37LG30.
They all seem to have the same factory flaw.
The plastic bezel and rear is vibrating against itself I have found.
Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area.
The two plastic pieces are vibrating against one another.
The vibrating was coming from the speaker area without doubt.
The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me.
As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away.
I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in
Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies.

The LCD Panel is defective. You will need to replace the LCD Panel. It will probably be cheaper to replace the monitor since the LCD Panel may exceed the monitor cost.
Single lines of single color (red,green, blue) are LCD panel failures.
1 or 2 lines of single color are LCD Panel failures.
Multple color lines could be anything so in this case you start by checking the power circuit.

I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.
