Hi,
I bought this Viewsonic monitor (VX2478-4K-HD)only a year and nine months ago, so it is not an old monitor, but I did use it everyday and a lot of times, I left it on all day. Anyway, the monitor started having problems a few months ago, when I turned it on, it would take a while for the display to come on, so I stopped turning the monitor off, and put the monitor to sleep instead, and the problem went away for about two months, and then it started again a few weeks ago, after I put the monitor to sleep, it would take about 5 mins, and then 10 mins, and then 20 mins, and then 40 or 50 mins(taking increasingly long)….for the display to come on again. I thought there might be something to do with the dp cable, so a week ago, I turned off the monitor and changed the cable, and then after I turned it off, no matter how long I waited this time, the display wouldn’t come on again. I did some research online, and it seems that these are the common symptoms for failing capacitors, so I opened the monitor yesterday, but sadly, all capacitors seemed to look fine(right? Please see the pictures), I didn’t see any bulged capacitors, and in fact, everything looks shinny and new, so now I am not sure what the problem is.
Basically, when I turn the monitor on, the little led blue light is on, there is backlight, but no display, and the “no signal” message doesn’t appear as well.
Any ideas what's wrong with my monitor? how to fix it? Do I need to change the capacitors? Which capacitors should I change? How long do the monitor capacitors usually last? Which one is the fuse(I don't seem to see one on the power board)?
Thanks,
P.S I don't think this problem has anything to do with the power adapter, right? since there is backlight, should i try a different adapter ?
