Double posted why? OP.?
NO,caps need to be new and fresh never old.
old caps are no good. for repairs.
learn that if the used old caps short
it blows up the mobo, now is more expensive top fix.
use new caps only
not once did you tell what is in your hand at all.
or photo of it
there are lots of caps inside any monitor made.
and are not all the same at all.
my guess is, ELECTROLYTIC caps. large can shaped.
with big X or K embossed on top? called explosion preventives.
like 100uf and 50v or more?
do not use , used caps of that type ever.
buy new ones
here 92,000 choices in fact
alum caps called now, (not TANT)
on the left side see all brands there, those are TOP brands
no stinking counterfeit junk here. sold.
105C best, wild example, 100uf, 100vdc. low esr, my best brand.
show me yours and I will tell you what works best.

I guess this as this is 99% of most failures in the CAP world.
for sure found dead, 2008 C4 caps, china counterfeit crummy caps. C4 boom.

I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.
They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.

You need to isolate the problem to see if there's a problem with the monitor or with the sound card of the computer.
To isolate this problem, please try the steps below:
1. Make sure that the monitor is properly connected to the computer.
2. Check the volume of the monitor and the volume properties of the computer.
3. Try to connect your monitor into a known working computer.

This is indicative of either / or CCFL back lamp or inverter.
The CCFL is a Cold Cathode Fluorescent Lamp and the inverter changes DC to AC and functions a lot like a ballast for the CCFL. You'll probably end up buying both - unless you know for sure it is the lamp or the inverter ahead of time.
Prices vary on size of lamp, etc. Most suppliers offer both the lamps and inverters and have pages to assist selecting the correct CCFL & inverter online - one such is here. There are others, too.
Please rate my reply - thanks & good luck!
