Dell P780 17" CRT Monitor(3 yrs old) issue

My 'Dell P780 17" CRT Monitor(3 yrs old)' fads away gradually and goes blank completely for about 1 minute and comes back. This is happening frequently. I cleaned up the nVIDIA GeForce Graphics Video card (w/ fan) that gets hot quickly. Is there anything to clean inside the monitor. Is this due to Monitor or Video Card or both?. Please advise.

    I have a similar problem with my P780 manufactured in Aug 2000. Picture fades and comes back in within a few seconds, does not do it all the time, very intermittant problem. I know how to discharge the CRT and solder(even have a high voltage probe), if anyone knows the component that is failing, please post it. It still has a fine picture most of the time.

That sounds like a monitor issue, not a video card. Gradual fading means components within the monitor are wearing out. However, I strongly advice against attempting repairs. CRT monitors hold a strong electrical charge. People have been injured and even killed by attempting to work on them without proper tools and training. A 17" CRT monitor is too cheap to be worth the risk (you can often get them used... I got mine for $20 at Goodwill).

My dell monitor ultra 2000 goes blank after about 3 minutes then i turn it off and on again. the picture will show but have to keep resetting it. is it repairable?


Everything is repairable but CRT monitors are not worth repairing. Just about any thrift store or recycling center will have a load of them and most of those places won't even take them any more so it's real easy to find a free one.

Dell Inspiron 9400 display goes blank after a few minutes


If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st

No Display on connecting Data cable of PC


The Monitor is bad, with the CRT Monitors you cannot just replace the connections, because it is embedded into the CRT. So it is probably something that lies with in the monitor itself. Try to connect another monitor to the device. See what the result is, my best guest is the CRT Monitor when bad. Time to replace! Sorry!
