That was incredibly instructive. I am learning a lot about the use of the oscilloscope. What could have caused that broken ground in the voltage divider resistors? Also, in the discord you guys already pointed me to broken traces but I could only test for continuity in the main chips and could not find anything. Very interesting.
That GG has a great sentimental value to me. Thank you a million times. I am happy to see that the old GG helped in a sense: we now know more about the data pins and how they can be mixed. That "hairline" bridge I missed when I reflowed. My bad. Sorry!
That was one of the clearer examples of scope usage for diagnostic purposes I've seen. Very useful, thanks!
Hi, I just wanted to let you know that my Game Gear had the EXACT same audio issue where the ground was missing from the left hand side of R49. I bridged it to the LHS of C15, and my sound is back!
Thanks once again. This and your other video about Game Gear audio troubleshooting were both extremely useful.
Glad it was useful 😀
Thanks Bro, with your video I could finally fix my sound issue. Another GG back in life, long life Sega.
My GG's audio is now fixed, many thanks for the tips!
Very interisting job thanks
Wonderful work! I have a game gear board that doesn't play audio or load games currently so I wonder if I can fix it
I hope you dont mind if I keep repeating, but that was incredible!
Thanks. Hope it's useful for people to learn some things from
@@RetroSix I am so sure, that I already bought two broken Game Gear to try!
Brilliant video thanks 👍🏻 could you please put some links for an oscilloscope that has enough features for this work.

very interesting ! i got a problem like this with a GG just recap who dont want to read any game, what is the model of oscilloscope are you using ? can it possible to do it with multimeter ?
thx so much !
I have one I am working on right now thats got a good audio board thats been tested but still no audio. I accidentally shorted the right audio channel and test/ground when re flowing ic3 which gave me beautiful loud audio.. but when I put headphones in somehow I only get left channel. I did hear some audio coming through the right ear but it was very quiet. If anyone has any idea where else on the board I should be looking I would appreciate it! I cant see any obvious bad traces and re flowed most the connections over there. The strange part is that before I did the re cap. I had some super quiet audio.. after everything but audio is working. I know its not the caps because i can make it work bridging that connection.. but its only the one channel.
Hello, i have a problem on my GG , i replace all the capacitor, the game launch , the sound lauch but nothing at the screen , only dark or white but the screen work , the brightness work .
I look all the motherboard and in see a Cms capacitor is missing near the Asic right just upside ( the capacitor C14 is messing , between c85-83-84 . can it be the problem ? thank you !
I just bought a GG on eBay. Initially it powered on, NO SOUND, and I could see a faint image of the game playing at a VERY particular angle. But it did play.
After recapping the power, sound, and main board, I now get audio, but only a white splash screen. Adjusting the brightness know has no effect, and I can no longer seem the game play at any angle, I can only hear sound, which sounds great.
I double checked my work, and have very good soldering skills.
Is my screen just done for? The contacts on the game cart, as well as the Colson card slot look fantastic.
Any help would be greatly appreciated.

Hello. I have a 1 asic game gear. After recap, it can show the license screen but can't load game. How to test it? Thanks
This video shows you exactly that
I have some VA1 1-ASIC Game gear which red light boots fine, but does not read any game. All address and data lines appears to be physically fine (tested with multimeter), but the signals looks not the same. My cheap china oscilloscope might be to bad for it, but at least I could confirm the RESET and 16.7ms VSYNC signal. Does this prove no faulty ASIC? The board looks immaculate and I did not find any short to ground so far. Any idea where else I could search?
You would need to check address and data to work RAM too as well as cart and ASIC and test with a game with the top lid off so you can prove the cartridge is ok too
@@RetroSix Thanks for fast reply! Cartridge is ok, works fine on another Game Gear. I have signals on all pins, but they show different, as my oscilloscope ist not very good. Is there any way to check ASIC/RAM without oscilloscope? Might not be worth 200€ for one repair...
It's the only way to really check. We sell a £59 oscilloscope in Equipment section
Hi
I replaced all caps on 2 gamegear and now I’ve display half working and half black in one and vertical linee in other. I have sound!
Jump on discord.gg/RetroSix for more help and share video of issue
@@RetroSix thanks. Where do I post the problem?
Handheld gamegear section
On my Game Gear the sound works using headphones but not the built in speaker. Is this a capacitor issue or speaker?
Issue is on the sound board. Could be capacitors, broken trace, bad amplifier, bad speaker, bad headphone connector ground pin
@@RetroSix Thanks, 😒😢🤔🙄🤢
Could you make a repair on a game gear only using a multimeter? Thanks
Yes I can show on next repair what tests you can do with only a multimeter but they are much more limited
Hi! That would be really interesting! I am stuck also with a non booting games, game gear.
There are three versions of the Sega game gear 2110g 2110k and 2110 the 2110g had two acis chips and the 2110k and 2110 had one acis chip
Just recapped my game gear all running recap soubds bored getting no sound not even thru headphone jack any surgestions
Check retrosix.wiki for the Reading Game Cartridge section so long as you have red light boot
