    Gateway lines in picture

    Hello, I`m noob here so sorry for somethink what probably was here but I can`t find solution simillar to my problem. I have broken Gateway LCD 19" which I bought on eBay for few pounds and this monitor have vertical lines in the picture. I google it this problem and somewhere I found that can be problem of 470uF 25V Samxons capacitor so I changed them but with no luck. I make 2 pictures of the LCD and on each one is different picture so I think this will be still some kind of capacitor problem, maybe is something wrong with that 100uF 450V so I will probably change it but before that i would like to know some other opinion.









    Many thanks for answers.

      From what I can see from your very large photo's, its the display that's faulty. That symptom is normally a fault with the connection of the driver chips to the display glass itself - they are held on with glue and its not unusual for them to come unstuck giving exactly the symptoms you show.

      There's a chance it could be the flexi-cable/wires that connect the display to the main board - wiggling those with the monitor on should soon show if there's any problem there.

      But, if as I suspect, its the driver chips themselves then there's very little you can do. I've managed to botch a few myself before now with a bit of paper to push the connections back into place (once you've spent the time gently flexing them to find which one is faulty) and that's still working OK, but YYMV.

        looks like that panel got whacked.
        look at the dark streaks in the damaged area.
        the panel is damaged.only fix is replacement.

          If you take a good close up of the backside of the glass panel with the identification,
          I can look around to see if I have one.
          The viewsonic I took apart yesterday, shown here broken,
          has a Chunghwa 17 TFT panel.

            Thanks mates, I just disassembled the LCD and you are right, LCD is cracked. I thought that is some dust because picture was almost normal...

            I looked on the back side of the LCD and I find that`s manufacturer is HannStar and model of the LCD is HSD190MD12 rev. 0 so if someone have this LCD I`am interest it to buy it.

            Many thanks

            P.S. Sorry for those big pictures and for bad english.

              Here's the 15', you'll have to use black paint around the extra four inches.
