Re: Viewsonic VE710b
Caps all seem solid. I don't think that is the right manual. I'm not seeing any reset switches.

Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.

I've got a monitor on my workbench at the moment that makes a high pitch squeal (that I cant hear as my ears are too old) when you power it on and lasts a couple of seconds before quitening and apparently it can be heard at regular intervals whilst on.
On opening up the monitor and looking at the PCB the usual suspects showed their heads so I have already replaced all the electrolytic capacitors.
The other issue that was reported with this monitor was the fact it took ages to start displaying anything after pressing the power button.
What component(s)...
