    Re: Hp 1502

    i'll give it another try tonight as I got stuck in the last bit as there was like a chip connected to the last frame and the screen.

    I'll try again tonight. I do have a faulty laptop which I can remove the bulbs from.

      you may not need to remove the bulbs we can try an talk you through just using the whole panel- laptop bulbs are quite fragile.

          Bulbs from the laptop?

          Is the plug the same as on the monitor - if so just substitute it.

          Is the plug the same as on on the other monitors?

            So, I have managed to dismantle the bulbs from this monitor and I also dismantled the bulbs from a dell monitor.

            The thing is that Dell use a different socket plug and it is a double bulb. Do I need to cut the wire and solder it to the HP's Plug or do they have some sort of holder?

              Can you post pictures of the ends of the bulbs in the respective
              Threads - Just in case we cant see are the ends blackened or the wiring
              burnt

              EDIT post pics of the plugs as well

                    I dont suppose you would be lucky enough to be able to get the metal pieces to com out of the plugs ( To save cutting the wires)

                        No dont try to get the Bulbs off the wires.

                        On the other ends can you get the metal pins to come out of the plugs?
                        I have just tried with an lg monitor and if you look at the end of the plugs
                        There MAY be two holes if you insert in a needle into the hole without the pin
                        and pull on the wire it MAY come out. Mine did

                          Re: Hp 1502

                          i had to cut the wires in order to work but anyways... so i had connected this bulb with the board and when powered it up the bulb turned on.

                          So now my question is, how can i fit this bulb into this monitor as it is different ( i.e. 2 bulbs going into one holder and I do need them to be separate and go into my holder.

                            Ok I dont know if they will separate - would be good if they did then you would still have a test bulb - If they both fit in the space where the one came out then perhaps try it like that for now until you see if you actually get a picture on the monitor.
                            Then if you dont it can still go back to where you got it from.

                              it can's fit as the Dell one has 2 bulbs as shown in the previous post, whereas the HP one's are single one's. i will try to take off the holder with the wires although i think that it is impossible.

                                Wish I could see what your doing - You are doing really well with the improvisation so far. Just checked your only 1 hour ahead - thought it would be at least 2 even though I visited Malta earlier in the year I forgot. We stayed in Sliema and travelled around on the public bus- it was great.
                                Im off to bed - busy day tomorrow.

                                  Have you ever came to Bugibba? There is where I live. The public bus service is not too convenient though hehe.

                                  In the meantime can you please help me with my other New monitor hehe?

                                    Will look at the other post.

                                          well I have managed to fine a similar vga cable in an old crt. I have tried it in and now the backlight lights up, it shows going to sleep mode and the monitor's power led turns to amber.

                                          Any suggestions?

                                            Hi,

                                            I have 820-4924 board that has keyboard and trackpad problem. I suspect it is logic board issue.

                                            I was told that in attempt to repair MagSafe charger wires were mixed up and therefore it does not power on.

                                            Using PSU machine starts and is stuck at the folder with question mark. If I put USB drive with macOS it start in the installation wizard, but keyboard and trackpad do not work.

                                            I checked voltages at the keyboard and trackpad connector:

                                            PP3V3_S4_TPAD 3.3V
                                            PP3V42_G3H_TPAD 3.42V

                                            Today, my daughter's HP 1502 (P9617D) monitor (3 years old) was pulsing on and off (with a flash of video). I tried it on another computer with the refresh rate set within the monitor's specifications - same result.

                                            Later, I opened up the monitor and found that all but two (one of them was an LZ series unit) of the low-ESR Hermei capacitors have bulged .

                                            The list of the capacitors used as below (I cannot find datasheets for the Hermei units) :

                                            C922, C925: Hermei LE 1000uF 16V, low impedance, general purpose, replacing with 1000uF 16V...

                                            NVIDIA GeForce GTX TITAN PG600 Schematic & Board View

                                            The GeForce GTX TITAN was an enthusiast-class graphics card by NVIDIA, launched on February 19th, 2013. Built on the 28 nm process, and based on the GK110 graphics processor, in its GK110-400-A1 variant, the card supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. The GK110 graphics processor is a large chip with a die area of 561 mm² and 7,080 million transistors. It features 2688 shading units, 224 texture mapping units, and 48 ROPs....

                                            NVIDIA GeForce GT 1030 Schematic & Board View

                                            The GeForce GT 1030 was an entry-level graphics card by NVIDIA, launched on May 17th, 2017. Built on the 14 nm process, and based on the GP108 graphics processor, in its GP108-300-A1 variant, the card supports DirectX 12. This ensures that all modern games will run on GeForce GT 1030. The GP108 graphics processor is a relatively small chip with a die area of only 74 mm² and 1,800 million transistors. It features 384 shading units, 24 texture mapping units, and 16 ROPs. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GT 1030,...
