    GameBoy DMG-01 isn't loading Games at all

    thank you for the help. seems the same distance , so i guess ill order 2 chips and update when ever i get them . the only difference that i notice is that the 5164 comes with long legs , but it's not supposed to be an issue . if i'll manage to fix the Gameboy it will be a miracle. D

    ohoo that's great , do you know what is the difference between LH5264N4 and LH5164LN-10 , it looks that there is many 5164 chips but no 5264 . i can even get it on Aliexpress...

    so i changed the Shortened resistor with a new one , now the negative voltage is correct (-19) . but still it can't load games , reflowed the CPU and the Memory connections and nothing changed . the black bar logo is missing pixels . i don't really know what else should i check ......

    thanks for the help, ill try first to change the resistor on the DC convertor and see if there is any change . what I didn't mentioned is that sometimes I get the full black bar loading logo, although most of the times there is holes in it. i will try to go over all the soldering points again...

    thanks, its seems like you are right , its 1 ohm , when i measure it i get 0.2 ohm. ill have to get a new one replace it and check the negative voltage again. do you see it in the schematics ? because i can't find 1 ohm resistor anywhere

    GameBoy DMG-01 isn't loading Games at all

    got a new lead on what might be the problem , at the beginning there was a broken trace on the DC Convertor that i fixed . i checked the board again and the voltage im getting is really strange , for the 5V im getting it but instant of the negative 19V that i am suppose to get , im getting...

    WOW you actually disassembled it to the metal level , its crazy - i guess i'll have to do the same , any advice on how to get the pins out of the connector ? is there an "easy" way to do it ?
