dirtwarrior Posted August 9, 2007 Author Share Posted August 9, 2007 The power supply is intergrated so not easily fixed. How long do you think the monitor will last? Link to comment Share on other sites More sharing options...
puntoMX Posted August 9, 2007 Share Posted August 9, 2007 Well, you are wrong there, when it’s integrated it’s easier to fix then an external power supply (well you could by a new external one, but those are expensive). Did you open de metal box? Link to comment Share on other sites More sharing options...
dirtwarrior Posted August 9, 2007 Author Share Posted August 9, 2007 I havnt opened the metal box yet. When I do what do I look for? Link to comment Share on other sites More sharing options...
mark Posted August 9, 2007 Share Posted August 9, 2007 @dirtwarrior- Would it be possible for you to post a link to a picture of the inside of your monitor? puntoMX might find it useful and I am very curious as to what it looks like in there.DL Link to comment Share on other sites More sharing options...
aszwet1 Posted March 10, 2008 Share Posted March 10, 2008 i'm getting the same problems as you dirt warrior... did you ever resolve this issue? Link to comment Share on other sites More sharing options...
newsposter Posted March 10, 2008 Share Posted March 10, 2008 how about checking the monitor power down settings in the computer...... Link to comment Share on other sites More sharing options...
dirtwarrior Posted March 10, 2008 Author Share Posted March 10, 2008 When the main screen comes on it last maybe a second. Link to comment Share on other sites More sharing options...
newsposter Posted March 11, 2008 Share Posted March 11, 2008 but did you actually check the powerdown settings? Not the screen saver, but on control panel|powerAnd have you tried another video card before you start tearing down a costly LCD panel with no real knowledge of what you are doing.

aszwet1 Posted March 11, 2008 Share Posted March 11, 2008 how about checking the monitor power down settings in the computer......my best bet is there is something wrong with the caps on the monitor board... that seems to be about the only thing i came up with on google.... there isn't much but what there is isn't in english Link to comment Share on other sites More sharing options...
puntoMX Posted March 11, 2008 Share Posted March 11, 2008 Cool that we bring up this topic again.As I’m fixing more and more screens these days I found out that it’s a general backlight problem with many models/brands.Most of the time it’s a problem with bad transistors that drive the backlight coils, bad soldering points and the coils them selves.To replace coils will be hard as they are not sold at your local electronics-store, however, the transistors are basic pull-transistors that can be found in almost every electronics-store and re-soldering the bad/cold points is a peace of cake.

aszwet1 Posted March 11, 2008 Share Posted March 11, 2008 (edited) so how do we go about figuring out which are bad points and all that jazz? is there a decently easy way to do this?also, i got mine for free from an aunt and uncle, they said it didn't work, i had it running for about two days and then i turned it off, when i went to turn it back on is when it didn't work... i'm letting it sit for a while, but i'd like to fix it 100% Edited March 11, 2008 by aszwet1 Link to comment Share on other sites More sharing options...
puntoMX Posted March 11, 2008 Share Posted March 11, 2008 my best bet is there is something wrong with the caps on the monitor board...There are no capacitors that drive the backlight, however, the power to the backlight module has capacitors but if those were damaged then most likely the screen would not even light up.i'm letting it sit for a while, but i'd like to fix it 100%Exactly, you have bad transistors; they overhead fast and thus aging goes faster too. Replacing them isn’t hard if you know soldering a bit, but before you remove them I would check your local electronics-store if they have them, or at least can order them. They should be cheap and you don’t need more then 6 of them (never saw a screen that used more then 6 and 2 coils). What brand/model do you have? HP?...

aszwet1 Posted March 11, 2008 Share Posted March 11, 2008 kds k917s, 900d.how do i know which are the good and which are the bad ones... i'm a n00b when it comes tho this kinda stuff. Link to comment Share on other sites More sharing options...
puntoMX Posted March 11, 2008 Share Posted March 11, 2008 Replace them all, they are cheap; let me see if I can find the module lay-out. Link to comment Share on other sites More sharing options...
aszwet1 Posted March 11, 2008 Share Posted March 11, 2008 (edited) Replace them all, they are cheap; let me see if I can find the module lay-out.like those are what i'm replacing right? and i can't find any blueprints or whatever for the boards... also i'm just replacing the powersupply board right? not the one with the chip in it or whatever? would pics help?
