Here's my issue: my screen (a Samsung SyncMaster 245B) stopped working recently, the blue LED indicating power still lights up, but the panel itself stays black (it usually shows a grey box when nothing is connected to the screen at the very least). So I'm wondering if the panel itself is dead or if it might be another problem.

And I'm also wondering in case of the actual death of the panel, is it worth replacing or should I straight up buy another screen instead?

Thanks for your time and your answers to come ! :)

After this monitor is on for a few minutes, the unit has a audible hum - a dead giveaway for bad capacitors. I have ordered 35V 220uf capacitors for the inverter to see if that fixes the issue, but if this doesn’t, what should I focus on that’s cheap? The capacitors on the power supply look okay, so I don’t think it’s those although I do suspect it having experience working on multiple monitors I was given in the past that tell me it probably is. If I let it run for a while it clears up and goes nearly silent, but it's still an issue.

If it is the power supply caps, is it okay to ignore the AC side and just focus on the DC parts of the display? It usually is safe to do so in my experience, but I have yet to do it on a monitor with more then 2 CCFL connectors - this has 6.

In addition to those checks, I did run it without the inverter connected to the power supply and it was more or less gone at the same time I was checking it out to isolate the fault - hence why I’m working on the inverter first.

The second reason I am asking is this person also has another Samsung monitor from 2015 without HDMI. When it’s time to replace their Win7 computer I don’t trust to be properly Win10 compatible (although I am open to trying if they want to!!!), we may reuse that monitor. If we do I'm concerned with how compatible it will be now that I’ve encountered this problem with the old monitor from the same brand.

What is the success rate with this monitor and the HDMI adapters? Normally I would look at a write-off on such a monitor, but this is a 16:10 1920x1200 and these aren’t the most common things - partially because the people who use them tend to hold onto them. I’m reluctant to spend a lot on repairs, but what could cause this strange incompatibility?
