    Hello... any updates on the 1800FP? I just got one in with the same problems. Steady green light, good 12v and 5v, nothing else.

            If it is the eeprom, you can purchase a preprogrammed one. Refer to link below and read post #18:

            You'll have to use something like ChipQuik to remove the old eeprom.

                Success!... I did some ESR readings of all the surface mount caps on the board, and found C817 a 100u 16v cap with 2-3 times higher value than the rest. I swapped it with a radial, and it worked! C817 is next to the two other radials on the board. Hope that helps.

                    AOC 27 monitor Q27G2WG4 doesn't display logo or image on screen
                    by 3D Modelka
                    Hello. I have a problem with my AOC 27 monitor, specifically model Q27G2WG4, which I have been using for 3 years. The monitor stopped turning on: when I turn it on, the backlight turns on, the indicator starts glowing white, but the logo on the screen does not appear, and there is no image. However, if I check in the Windows system, the monitor is displayed as connected and working. I tried connecting it via HDMI and DP, but the result remains the same. If I turn the monitor on and off multiple times, it will eventually start and work. However, when the monitor is working, there are no issues....

                    I need help with my friend Sony GDM-FW900 24” CRT
                    by matthewmcconaughey
                    Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

                    I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.

                    Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                    by Ryan.man
                    Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                    My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                    This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                    Monitor Audio RSW12 - Green light but no audio
                    by MOSSEP
                    Hi

                    Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

                    Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

                    The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

                    I have already tried replacing all of the...

                    A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
                    by abajor
                    Having this very weird issue.
                    The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

                    I swapped with a working screen from an A2141 waiting for parts.

                    The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

                    The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...
