        Hi...
        "with the Proper power supply" what do you mean with this?
        "Is there a way to test the lights in the panel it self ?" another monitor/inverter or other known good lamps.. or the trick of disabling the protection temporarily..
        about your supposed bad cap i saw the board on sale's picture, if you mean the black cap put on its side that under it is only normal glue.

          The Proper Poser supply I mean .. the original was not given to me .. so I used a 12 volt 2 amp one .. I got the proper one now .. a 12 volt 6.6 amp

          Replacing the * 2 bad caps on the board the power does now make the green light light up , and it stays green when hooked to a PC .. but turns orange after a bit when not .. So I know the monitor is getting a signal and knows it . I just do not get any screen to come up .. I have tried the " 2 finger " Reset but does not help .

          With the other power supply I would not get a green light , until I replaced the capacitors , but after replacement , I would get a green light that went orange soon , even with the PC on . So the lack of proper amps must have caused that .

          * The 2 bad caps were in align with a third that did not blow its top , Do I need to change that one out too ?
          Also do I need to check Fuse's after they are removed ? as all appear OK while on the board .

          Thank you again for any help ..

            "the original was not given to me .. " So i guess that is an external one..(??)
            "So the lack of proper amps must have caused that" Let me understood.. with the original and with the other psu is the led behavior the same (first green then orange..)?
            "Do I need to change that one out too?" there's no picture of psu or board where psu goes .. no schematic, so i can't tell this..
            "Also do I need to check Fuse's after they are removed ?" No.

              .. The monitor acted different with the 2 different power supplies .
              The one that came with it was no longer putting out power so the guy tossed it after I bought a new one . The one I tested it with was one I had that was lower on amps then what the original had .



              That is the Power board .. The red circle is where I replaced 2 of the three.
              470 uf 10 volt .. I only had 470 uf 25 volt available to use.
              the under side of the board shows that they were all connected parallel .

              Here is the Video board .



              When I bent the dark one in the corner up to read it's size . the leads broke .
              I can put a 25 volt 100 uf in its place . it was by reading the part number and going to the manufacturer web site it was a 10 volt 100 uf .

              If the Panel is dead I am not going to put anymore money into it . ( the guy does not want the monitor now , so If I can't fix it I am out the $'s the new external power supply cost me )

              How can I check to see if the panel it self will light up ?

              Thanks ,

                Well fuses are all ok .. a few other caps dont seem to hold steady when I check with ohms on meter.
                I wonder if the CF tubes are broken or non functional .. any way to test ?

                    the 6 on the board the power plugs into

                    The monitor power light stays green when I hook up to a system as a second monitor .. Win 7 even recognizes it .. if I disable it , the power light goes amber .. as expected

                      Six fuses? This unit has six lamps so even one or two are broken, at least you should see the working lamps flash on for seconds before the inverter goes into protection mode.
                      We need the straight shot pictures of the inverter board top side and bottom side, the pictures must be clear enough to see traces on the traces.

                        Can we have good clear pictures of your boards posted using manage attachments
                        not posted off site.
                        They need to be like the original posters so we can see what you are talking about.
                        Mark up the board with the six fuses you have tested.

                        The problem you are having probably relates to fuses on the inverter board I think I see 1 fuse - its pretty blurred the original poster has 2 so please check They will be labelled F1 and F2 in all probability

                            FB = Ferrite Bead (it's basically a very small inductor), they are not fuses.

                                    OK, check and report the DC Voltage readings at both ends of these two fuses which feed the B+ to the inverter transformers drive circuits.

                                      I got voltage on one end of both fuse's and none on the other with unit plugged in

                                      2.0 = .. 2 amp fuses?

                                        They should have 12VDC at both ends of the both fuses, so it means that those 4 SMD POWER MOSFETs (8-leg SMD) above those two fuses may be shorted out that caused the fuses to blow. We will need the P/N as printed on top of those 4 devices.

                                          Ok I get the numbers I did have 3 bad Caps I replaced could that have blown the fuses ?

                                            Problem

                                            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                            Hello everyone !

                                            My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

                                            Hi everyone,
                                            I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
                                            Laptop came in for a SSD upgrade, took everything apart to install the SSD.
                                            Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
                                            Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
                                            The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image

                                            Symptoms are:
                                            - random black screen after displaying Acer logo...

                                            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                                            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                                            Weird issue with this tv. Was streaming to the from a computer when it stopped working and the screen went black. Ever since then there has been. o image. Just a black screen. The audio works and yhe backlights do come on when it's powered on, it's just a black image. It presented like a backlight issue. So I finally got around to getting new backlights and a backlight tester. All of them test the same as the good backlights with the same voltages. There are no blinking lights. Just the white led at startup and when buttons on the remote are pressed signaling it's receiving from the remote....
