I don't like this type/style of video.

"How to repair Samsung .." - you make it sound like this is the universal repair solution for that monitor. You're only showing a repair for one problem. Add "black screen" at least to the title.
The "black screen" problem can be caused by lots of things (faulty ccfl lamps, damaged transformer etc).. bad capacitors is only one problem. Your video makes it look like anyone with black screen problem can just blindly go and replace those exact three capacitors and he/she will fix the monitor.
No mention of checking the OTHER capacitors which may as well be bad, but may not show signs of failure on your particular board
No explanations about how to remove and install new capacitors, what capacitors to use, why those fail, and so on and so on.

i dont like video-repair things at all.

i get sick of non-engineers messing stuff up because of something they saw on utube or telling me i dont know what i'm doing because of something some preacher on utube said!

for this monitor, i found out that the main caused is the bloated e-caps, if there is another problem with this monitor, i include it but thanks god it is only capacitors.

Why is it that on almost every forum, there are those pros that like to bash amateurs that are maybe just trying to help someone out.
A LOT of old 17s and 19 did have common issues with caps
This site is called badcaps !! Not bad transistors or ccfls or etc ???

I didn't watch the video, but still !!
If you don't like videos, don't watch them

Honestly, I am surprised you guys wasted time looking at a video on an antique 17" ?? I would think you would have better newer stuff to try to help with.

Ever look at your first posts ??

don't give up dig29089

It's a Youtube video, Google will index Youtube videos and give them priority, so they'll show up ahead of badcaps threads.

As for your question, it's because sometimes amateurs search for their monitor model numbers and find videos like that one and buy shitty capacitors before they open up their monitors and then the fix doesn't work because his monitor maybe has bad ccfl lamps, or a fuse blown.

Or maybe it's not those three capacitors in the random guys monitor, maybe it's other cap, maybe it's something else. The video doesn't stop to explain why those capacitors are the problem, doesn't suggest other fixes, doesn't suggest what a random guy should search for or inspect, doesn't suggest WHAT PARTS to buy (noob gets shitty caps, they die in a few months)...

I'm not saying the guy should give up trying to help, I'm just making some (hopefully) constructive criticism.

Watch the video, and compare it with some other youtube videos, for example this guy's videos are very good: https://www.youtube.com/watch?v=L8nj3CpiEKY

After I repaired this old monitor is still using in our company, yes, that why we are repairing to save money, 3 e-caps cost only few dollar compare to new monitor which cost 100$ or less in our country.
