    Another Dell 2005 FPW

    I have another Dell 2005 FPW monitor with this problem. It has vertical lines thru out the screen. It not that the pic is blurry, but I took a small movie of the screen then took a screen shot of it. At least the screen comes on on this one. Maybe between the 2 I can make at least one of them work. Have not taken this one apart yet. Wanted to get some ideas first.

    Re: Another Dell 2005 FPW

    that sounds like it could be the ribbon cable or logic board.

    you said you had two of the same monitor, but the other one does not turn on?
    you could, if they use the same internals swap the power board with the one that doesn't turn on, and might have yourself one of them working.

        I would do it the other way round= as this screen is sort of working then the boards must be sort of working- so try the screen off the other monitor on these boards.


        Did you have a known working source connected to the monitor

            OK I used the invertor board from this monitor and the main board from the other monitor and this is what I get now.

              I'd swap the PSU's from both of these monitors.
              Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

                The one is bad, see first post. Inverter is bad on the other one.

                  Re: Another Dell 2005 FPW

                  Well I started trying to adjust brightness and contras and it has stopped making the arcing sound in the lower left hand corner and the screen is solid! Put it all back together and turned it back on and it was flicking just a little but went away in just a couple min. I'm thinking bad solder joint maybe?

                      Maybe get the arcing noise back again and then check where it's coming from, and then reflow the solder joint.

                        It does it when it comes out of screen saver when its been off for more than 1 hour but stops after a few min.

                          It's still a good idea to pinpoint the joint and reflow. Could you trace it?

                              Do you smell OZONE! it sounds like bad solder joint at the end of the lamp.
                              AM radio is good for listening for arcs.

                                I don't smell anything and it flickers about 1 to 2 min then screen is great! It sounds like it's coming from the lower left hand corner of the screen.

                                  I would say you do have bad connection at the end of the lamp.

                                      is this same one you have?
                                      http://s807.photobucket.com/user/bud...?sort=3&page=1

                                      It uses six lamps!
                                      Look at the corner back side of the screen to see if there is any signs of problem in that corner of the screen.
                                      20" monitor may not be worth fixing, but you do have one bad screen that you can take apart, right? The one with bad lines does not make arcing noise, correct? otherwise you can swap the LCD glass panel to the with good lamps.

                                        This is the one that had the lines through it. I put the other main board in it. Your second link is the one that was in the other display, both displays have 6 lamps, transformers has 6 leads on one side and 2 for the output side. This one, the transformers have 4 leads on one side 2 on the output side. I'm thinking I tried both screen and the other one flickers then goes out. Hope you followed all that. LOL
