but do it and you tell us how it smokes,.... can we watch>?
try not to get electrocuted. 350vdc is not safe, lacking skills max.

the caps can dry out and not just bulge
a real tech test them all with a real meter.
they can
bulge
leak acid (boric)
explode
short
go dead open or be weak (low uF)
or crack or make tiny vocanos on the sides
seen them all me. every type of failure
I use ESR meter too.
you need soldering skills so as not to destroy PCB traces or pads thru-holes ripped out. rending it dead.
and what new ones are best, mouser.com
Nichicon.
Showing video of the first guy that only seen one kind of failure is no good.
bulges is just 1 of many, .
we test them. looking only shows 1 class of failure.
some leak acid out bottom.
some the acid eats through side of case.
counterfeits do that, in spades.
the big killler is heat.

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.
SOURCE: i have a viewsonic va1930wm. it turns off and on.
Is ur graphic card ok?
Have ur screen tested on another PC to determine exact cause...
SOURCE: How do I get the back off of my Viewsonic VX922
take out the 6 screws that hold the stand start from the bottom and spred the two covers apart at the split

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!

answer toss coin
if the uF marking is too low they fail
if the voltage is too low it shorts the cap.
why not buy new caps from Mouser.com
really you SHOULD not use old and bad caps, for sure 2007 caps known to fail. Cap Plague.
never use , used caps, for sure electrolytic.
you failed to show what caps these are.
buy them new at mouser.com
correct uF, and voltage.
never lower voltage.
and low ESR is best
as are brand good... Nichicon.
the answer is not guessing. you.
what if you moved bad caps to 2nd monitor and now has 2 times more bad.
how can that work>?? you tell me?
IDK.
I was doing this since 1965, so.... on vast types of gear, not just PC.
reCAPing is not a new idea at all
they are short lived and for sure counterfeits and clones.(of real)
be brand conscious here.

correct uF (electrolyics)
correct voltage or more (tad) if not too big size.
low ESR
not put on backwards.
and use top brands current,
Fresh, not old.
not plague years.
