Are you still using it as a computer monitor, or are you
back to watching television?

1) Make sure that the you have selected the correct
video input for your programming and that you have
a valid video signal connected the corresponding
input.

2) Does the menu come up when you use the remote?
Make sure that the remote is still in TV mode,
not in cable, VCR or DVD modes.

3) Most TV's will blank the screen to black when there
is no input. If you have recently changed the cabling,

e.g. unplugged the computer

the TV may still be stuck in computer mode,
waiting for a valid video SYNC signal to activate
it from a power saving mode.

Some TV's will also not wake up even to display
a settings menu, unless a valid TV signal is present,
due to idiotic design. (This is now rare for newer TVs)

4) Try pressing the MENU button or the INPUT SELECT
button on the remote, to see if the TV responds.

If it does, select the correct video input and you are done.
============================================

5) If the TV does NOT respond to the menu button
(on the remote, or on the TV itself)

re-connect the computer and make sure that the
computer is not in STANDBY or HIBERNATE mode.

Press a few keys on the computer's keyboard,
or briefly press the power button on the PC
in order to to wake it up if necessary.

wait a few seconds....

Does the TV come back on ?

if yes, use the settings menu to change the video input
to normal, before disconnecting the computer,
and you are done !
==========================================

6) Try all the external video inputs, by plugging in a cable box,
VCR, DVD player ... etc

To see if the TV wakes up

If it does, use the menu to select the correct input,
and your done.
==========================================

7) Leave the TV switch on, but unplug the power cord
for 2 minutes, to see if it resets.

By leaving the power switch ON, you are making sure
that any residual energy in the TV's power supply capacitors
is fully discharged,

in order to make sure a full power-on reset sequence
is initiated.
=============================================
8) I you cannot get the TV to wake-up or respond by taking
the above steps, the TV is probably defective and you
may need to contact the manufacturer for technical support.
=============================================

9) I checked the specs on your TV model, and it appears
that the TV is a true LCD monitor, not a rear projection
LCD chip, so there is no projection bulb to burn out.

If you want to see photos and a description of the disassembly process and commentary on my repair job, soldering in the new caps, etc. I've posted them online for anyone interested in tackling the job themselves. I've never cracked the case on a TV before, but thanks to some of the hints here, and some efficient Googling, I was able to fix my own set with a screwdriver, pliers and a cheap soldering iron, all for less than the price of a pizza.
