Gotta appreciate the love for the game gear. I recapped one recently with the retrosix pack and worked perfectly, hate to see retro tech going to waste.

Nice to see some tips for continuing to use the original screens. While I know people seem to prefer switching to better and newer screens, some original GG LCDs really weren't too bad, I know the one in my US VA4 is perfectly acceptable, or at least better than the one in my Japanese GG.

Very nice!! I change one but use lot of Flux and solder iron. The tricky job is solder again alined.

[@diwest1737]

Nicely done!

Hi, could you perhaps share the LCD signals on a good working Game Gear or how to tell if the LCD is bad? Thanks. After buying a broken Game Gear that was an "attempt to fix" by someone, I found out it was heavily corroded and a few mistakes were made in the rework also. I managed to fix it to a point where the game is loading, it has sounds, the lamp is lit and the contrast works. However the LCD which has all signals present, only shows a few lines but no other activity. For example, when loading the Collums game, I can see that the frame of the game(where the blocks would go) is set on the LCD but nothing else. When it switched to another screen, it updated to nothing. At this point, I'm not sure if the LCD is bad or there is still a PCB problem. Since I don't have another one, I can't tell yet. I will attempt to check the PCB again though.

Update: I found a fix. The problem came from R42 and C45 in my case. I remade the connections and it's working fine now. The PCB has a lot of straps now but no matter 😅👍🏻

Great glad you found the issue

[@ledste1]

Which is the suggested temperature for hot air? Thanks

[@RetroSix]

Depends in each situation, specifically for the GG ribbon removal I would run at 480C and 80% air would be fine

@@RetroSix many thanks

Hi, Retrosix u are my last hope :( i hope u can give me a tip, i have recap a game gear with 2 asic ic I use 5x 100 Uf 25v ( not smd format ) But when i Turn the game gear on i see only a light , the contrast make no sense its have 20k i have check it with multimeter ( wheel is not broken ) Is my LCD defective ? I see only a light and nothing more, no game to see , it is lightly dark but the wheel is not working for darker and light mode, i am end with my mind 😞 Please a Tip from Master himself 😔

[@lhfraga1]

hello. something about flickering GG original screen? i have some boards with this issue after recap (literally the same problem). both differential signals pairs and VM are normal, no unwanted oscillations (frequency and amplitude) in them. I tested it with the oscilloscope on the 5 contacts on the side of the screen to make sure it wasn't a problem with the flat. the flickering is just there and i can´t figure out what could be going on . Have you ever had a problem like this?
