I recently got a broken Benq EX3203T monitor, which is a curved LCD model. When I turn it on, it displays a picture briefly, but then the image fades away and is replaced by lines or random colors. After a few minutes, even more lines appear. I've checked for damaged capacitors, and they look fine, but I can't test them on the board. I also verified that a few ICs receive the correct voltage. Any insights on what could be causing this issue and if it's possible to fix it?

If you're experiencing BSODs alongside the monitor issues, you might want to collect dump files for analysis. If you can access Windows, check for files in C:WindowsMinidump. You can compress and upload those for further help. Small memory dumps are easier for diagnosis, and guides are available online to set that up.
It sounds like your monitor could have a failing T-CON board or potentially a more general LCD failure. If you're considering repairing it, the cost of spare parts will play a big role in whether it’s worth it or not.
I can't view the image links, but from your description, it sounds like it might be a bad LCD panel. Repairing monitors like this often isn't worth it, especially with brands like Benq not having the same quality as they used to. You might want to look at alternatives like Iiyama for better options next time.
