Question about NEC Diamond Pro 930SB 19" CRT Monitor

Mitsubishi diamondpro 930sb flickering

Recently, my monitor has been 'flickering', meaning that there are 'lines' that run up and down the screen, and sometimes more severe white and black lines that look like static, or something. And once in a while, the entire screen diminishes to a 1mm tall bright white line that goes across the screen. Is this a serious, horrible problem with my monitor, or can I get it fixed? I love this thing to death, but I fear it may be on its last legs. Thanks, Andrew

I have had the same problem with my 991sb and most recently my 930sb. The first was replaced at NEC's expense however on this second one i'm out of luck. I think its a problem with its power inverter. It may be repairable by a tv repair place. I'll be looking into it and let you guys know.

I have the same exact problem. I was thinking it was some distortion from a source i cant detect. Changed the cords switched the Vcard inputs to DVI whatever i did its the same. I got a 17" NEC Multisync Fe700+ standing right besides the 930Pro, It works absolutely fine although i got it from hte basement from junk... pretty sad about this bought it 3yrs ago paid quite a bit... had big hopes for NEc and Sony tube..:(

Monitor flickers with lines across screen

screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

Vertical lines accross the screen

Vertical lines running down the screen is indicative of a data failure to the screen itself, which means either the screen is starting to fail or the data being transmitted through the data cable is being interferred with. Put a hand on either side of the monitor and give the monitor a light twist....does the line disappear? or do more lines either case, there is a problem where the data cable attaches to the lcd panel itself. You can try to change out cables, if that doesn't correct it, then the panel may have to be replaced. If you have the option of trying the computer on another monitor that would be the first step in seeing where the problem lies.

The screen on my laptop flickers colors and there are lines running through through middle red blue green ect.. it does work on an external monitor tho could this be the lcd inverter

Lines on the screen means the LCD is bad and needs to be replaced. The inverter just makes sure the lcd turns on. That wouldn't cause lines on the screen.

Mitsubishi NEC Diamond PRO 930SB Monitor - cover removal?

Remove the screws as you have done. Looking at the monitor front on you'll see 3 bits sticking down from the top (in the deatil gap) which are clips unclip them by pushing through the corresponding holes along the top. Also there's a clip at each side on the underside of the monitor which are very obvious. With the monitor facing down and everything unclipped just pull the cover upwards. It's not easy but work your way round the front edge and it will come.
