dirtwarrior Posted August 6, 2007 Share Posted August 6, 2007 I just traded around and got a KDS lcd for free. My first lcd. I hooked it up and everything is fine for a few seconds then the screen goes blank. The power lite is still lit but no display. I can turn lcd off then on and everything is fine for a while.Is my monitor shot? Link to comment Share on other sites More sharing options...
puntoMX Posted August 6, 2007 Share Posted August 6, 2007 Looks like the monitor has a heat problem that courses false contacts or so...No warranty on it? Then I would open it and reseat the cables inside the screen: just pull them out of the contacts and put them back in. Be careful if you use contact-spray that you don’t spray on your display, which could heavily damage the screen… Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 7, 2007 Author Share Posted August 7, 2007 Thanks I will try this.The monitor was stored in a cold storage shed the previous owner told me. Could this effect it some how? Link to comment Share on other sites More sharing options...
puntoMX Posted August 7, 2007 Share Posted August 7, 2007 It depends on the temperature, but you say that the screen looks fine for some time so I guess it didn’t affect it. If the screen was not packed the contacts could be oxidized when it was not stored in a dry place. I think you have to open it and look at it first .

Peteski Posted August 7, 2007 Share Posted August 7, 2007 this could also be a backlight issue, if the image is still shown but extremely faintly.what angle are you using the screen at ? Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 7, 2007 Author Share Posted August 7, 2007 I removed 4 small screws all on the same side of monitor (top), I tried to gently pry it apart but no-go, how would it come apart? Link to comment Share on other sites More sharing options...
puntoMX Posted August 7, 2007 Share Posted August 7, 2007 Some parts could be "clicked" together, so that means it was made to be assembled, but hard to take a part.Can you give the model number so I can see what model it is? Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 7, 2007 Author Share Posted August 7, 2007 It is a KDS K917sThanks Link to comment Share on other sites More sharing options...
puntoMX Posted August 7, 2007 Share Posted August 7, 2007 Hard to see with the info on the internet, but I’m sure it’s clicked together. Use your fingernails to open it a bit, not with a metal screwdriver that would damage the screen. If you’re lucky it pops open a bit or you can see where the click-connections are hidden.

dirtwarrior Posted August 8, 2007 Author Share Posted August 8, 2007 I got the plastic ring off, and took the 4 screws that hold on the screen. Many sets of wires plus a metal cover with more wires. Which ones do I need to look at? Link to comment Share on other sites More sharing options...
puntoMX Posted August 8, 2007 Share Posted August 8, 2007 Okay, let’s continue the operation .Now, unclip each connector and clip it again, starting with the one that comes from the screen... Check inside the connector if you can see some white or green oxidation...Peteski told you it could be a backlight problem, so I need to know how the screen looks like. It goes blank you say? Totally white? Or Black? Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 8, 2007 Author Share Posted August 8, 2007 It goes black but power liter stays on. Link to comment Share on other sites More sharing options...
puntoMX Posted August 8, 2007 Share Posted August 8, 2007 But you see something on the screen? Is there any backlight? Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 8, 2007 Author Share Posted August 8, 2007 Nothing on the screen. I asked the guy who had it before me, he said when left plugged into wall for a few days it worked for him. I left it plugged in overnite and now it works. What do you think is wrong with it? If I were to guess myself I would guess a cap going or gone bad in power supply. Am I close? Is this monitor going to quite me soon? Link to comment Share on other sites More sharing options...
puntoMX Posted August 9, 2007 Share Posted August 9, 2007 It could be a capacitor indeed. Did you look at them? In addition, does it have an external power supply? Link to comment Share on other sites More sharing options...
