I remember one time i was tired of buying batteries for my game gear and tried to use one of my brothers laptop batteries to hook it to the DC jack. Once i did that smoke came out my game gear tried to turn it back on with just batteries and it was a white screen with a red dim power light. opened it up, found a blown transistor lucky me i had a spare game gear with a bad main board and DC jack i ended up taking the jack off my board and putting it on the one with the good chip and transistor. the traces on the board was broke so i had to run wires threw it looked a little like this. It worked great after. those was the good on days it was in the fall of 1995.
Hello Great video! I have a DD, I changed all the capacitors video Ok, Ok power, but the sound before it was activated AFTER 1 MINUTE AFTER rather not Turn Over and feels very low, I tested the sound card and the power of another GG, and according to her work MAY depend on a transistor ??? Thank you very much.
Nice job 👍 I’m having a similar problem but I also have a broken power jack. How do you go about measuring the voltage of the pins? Where do you position the positive and negative to probes? I can’t quite make it out in the video.
Could be. Your best bet is to measure the output pins like I did and see what kind of voltage readings you get. Without at least doing that it's all just guessing.
I did nothing I bought a cheap charger not sure it's working so I bought used game gear power supply going to try that if I still don't have power at the charger port it might be charger port
I've never had to figure out if an inductor was good or bad, so I don't know a proper way to measure that. If you're getting absolutely no voltage readings from the pins, the first thing I would check is the power switch. Sorry I can't be of more help.
First thing I would check is the pins on the power supply board like I did at 5:45. First 2 pins should give you an output of 5 volts, 9th pin should be 34 volts. You can use the 3rd or 4th pin as the ground. Try checking that and see what readings you get.
Nice one, thanks for sharing! It's great to see you go through the debugging process...

Yeah the blue one right beside the power switch on the power supply board on mine it's lose could this be the problem with my screen
Bought game gear recap the power board nothing.no power. Any suggestions. Do you think it might be the transistor.

i´m so greatfull for your quick response!
already done that, completely nothing!
Can i measure those L1 and L2 inductors?

you can use an LCR meter, they cost like 60-80$ for a decent one
Very interesting video. Maybe you did already change the transistor?
Change all the caps but still no power, help?

Same issue with my gear die when I conceded a wrong power adapter
