![]() ![]() When I put it at the ohm symbol (which I can chose between 2000k and 200) I get a 1 in the display. #Gameboy dmg ac adapter vs how to#I think I wanted this post to end up with what to measure, and then I can figure out how to use my multimeter how to measure that. Thanks for the reply! Yeah you're right, I should start in that end. If the Gameboy works with an AC adapter, you at least know most of it is in working order and I'm sure you'll find the problem with careful examination. If it has a buzzer option, activating that can be handy so you don't need to keep looking back and forth between the display and the probes. You should be able to locate short circuits and broken connections by measuring resistance, if you get confused touch the probes to each other to remind yourself what a short is supposed to look like on your meter. In that case, is there supposed to be a connection, is the switch on or off etc. If "nothing at all" means no reaction from the meter, it means no connection. Getting "nothing at all" is a short circuit if "nothing at all" means zero resistance. When you measure resistance does a short circuit show zero on the display or does a needle jump to zero on a scale. Get to know your multimeter, does it have a digital display or an analog needle, does it show negative voltages if you connect the polarity wrong and will you notice the small negative sign on the display. However the area where it looks "bad" isn't something I can easily resolder but could it be that I need to add completely new wires?Īgain, any and all feedback is much appreciated but remember that I know very little about hardware and electronics like this and that the purpose for me during this exercise is to get a better understanding so please be patient with my stupid questions! I do think that the board looks a bit damage near the bottom left pin where the copper foil has been as seen in this picture. Is this expected or does this also indicate that there's something wrong with my positive terminal? When I try to do the same and put my multimeter 200 ohm I get nothing at all. I found this YouTube video where the author at the linked time (~10:10) measures resistance between the positive and negative terminal and is getting 100 ohm. Is this expected or does this indicate that something is broken between the negative pole and the board? ![]() ![]() If I put the end on the positive pole however, I don't get any connectivity at all. If I put one side on the negative pole I can measure the same ~6V almost anywhere on the board. Since I'm not really sure how to properly use a multimeter all tips regarding how to use one is appreciated! I tried to measure the voltage between the positive and negative terminal and it gives me ~6V as expected. I saw this post (about GBC) with the same issue and tried to clean the DC jack with a needle without success. When I had no success I dug out an old power supply and noticed that the console is booting up and working. The battery terminals all had some corrosion so I cleaned them up. When I opened it I saw that the copper foil look damaged so I wanted to remove it and have a look underneath. So basically the console looks to be in great condition but didn't power on. Here are images of all the parts and current state. Sadly after just two days I'm stuck and want to try to post here for what to do next. I'm a total noob and barely knows what a multimeter is so I bought a broken Gameboy to use as a learning resource. I've searched older posts, found a few with similar issues, most of them got resolved with solutions not working for me if at all. ![]()
