right click on your desktop / display properties (mine is nvidia display properties)

Recommend you verify where the video plug is inserted in rear of TV, there are video in and video out. If you have audio going in from cable/sat box, but video going to video out (instead of in), this could create the situation you describe.
Also make sure you are on the correct 'source' setting if you are using Video, etc.
Red power light is on but tv will not turn on...no
Dear quiltcat1,
With
the conditions as you say, there are components in the monitor, exactly
on the power supply board is not working properly or damaged and it
usually Capacitor.
The solution are:
1. Open the monitor case
2. Look for Power supply board, you will see there are some capacitors.
3. Look for bad capacitors which bulged at the top.
4. Just take out (you need a soldering tool in this step)
5. Replace with the same value of microFarad and higher values for Voltage.
for example: 1000mf 10V replace with 1000mf 10 to 25 V will be fine.
good luck.
regards,
dm

Cause of power going
off: There is a bad 1000uF, 16V cap
on the power supply board.
Solution: Replace cap. Radio Shack sells a 1000uF, 35V
cap for $2. This will work.
Why did the cap go
bad? The cap is too close to a heat
sink and over heated.
What does this cap
do? This cap sends a signal to an IC
which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is
applied to the IC and it sends a signal to shut the monitor off.
Opening the Monitor:
These monitors are difficult to open.
The two plastic pieces snap together and must be pried apart
with a flat screw driver.
After removing the stand, you need to insert a flat screw
driver at the bottom of the screen where two slots are located. Then work the screw
driver around until the two plastic pieces are separated.
Remove the cover plate and unscrew the push button circuit
board.
Unplug the monitor cords from the driver board and remove
the screen.
Unscrew the mounting screws from the power supply board and
remove.
You will need to pinch the plastic support in the middle of
the board to remove.
Cap Replacement:
Cap is located near a copper heat sink and the value will be
on the side of the cap. It will be bulged up on the top. You will see burn
marks on the board surrounding the cap. Unsolder the cap.
Install the new cap and solder. Make sure you connect + of
the cap to + marked on the board.
Be careful not to solder across joints.
Keep leads long so you can bend the cap as far away from the
heat sink as possible.
Reassemble monitor and turn on.
This should solve the problem.
