I have a problem ... It's a DTK monitor ... manufactured in 1997 ... The problem is that I don't have blue color anymore ... I know a little about "c. tube" and "RGB" & "canons" and how all together works ... My question is is it possible to fix that if I play with "RGB resistors" or there is no way because it's too old? I don't want to buy new one if I dont have to :) Anyone had similar problem? Thanks in advance, Anel -- www.suse.com [SuSE Linux] www.borland.com [Delphi & Kylix] www.firstlinux.net [Get free e-mail]

Hi Anel, I do not know wether its a good idea to repair a broken monitor, since you can loose more than a broken monitor. If one color fails, first thing is to check the cabling *to* the monitor, or rattling the cables to see what happens. Try another PC to eliminate the card from the list of causes. If you want to open the case, be aware of the high voltage. The tube itself will work like a capacistor, what means it holds high voltage for quite a while after the monitor is switched off and unplugged. It's not very funny to learn this by doing, btw. I'd check cables / connectors first, looking for dodgy soldering. This might be applyable for the entire board. Dodgy soldering might be a cause for color flickering, if a color stays off permanently, it's more likely that the color amplifier stage is broken. With that, your on your own, you need to "guess" where it is and there is no way to tell you what *exact* to look for. If you do not have any any clue about what I am writing, leave it. Personally, I am neither very happy diving into monitors.

I took an old broken monitor down to a certified TV repair shop. 20$ and doing fine 3 yrs later. Ask them to make an advance cost statement. Sometimes simple is good. BR, Gudmund
