But before I buy it, I wanted to know if can I just do without this particular diode or is it essential still Thanks for anyone who would help View entire discussion ( 10 comments) More posts from the Gameboy community Continue browsing in rGameboy rGameboy A subreddit dedicated to discussion of the Nintendo Game Boy. Press question mark to learn the rest of the keyboard shortcuts Log in sign up User account menu 5 Does anyone know a replacement part for RB100A D1 on the DMG. From a purely electronics point of view, Id just try adding a very common 1N4007 diode (through hole) and see if the whole thing powers up. Try checking if there are 5V and - 19V in D3 and D2 cathodes, respectively. The power supply module is based on a center tapped transformer that outputs 5V peak and - 19V peak sines. Dmg Gameboy Parts Series Of CapacitorsThese sines are then rectified by a diode, and a series of capacitors in parallel are used to reduce the ripple. Have a nice day EDIT: the diode model is RB100A (it says IG442K in schematics.). It is a schottky diode with a 0.55V forward voltage drop. What you see in the photo is D1 on the mainboard, which has nothing to do with DCDC conversion or IG442K. BTW, the schematic youve looked at has clearly been transcribed from a different source and theres several errors, so I recommend being a bit skeptic about it. For example, it lists 155254 diode (which is actually 1SS254), 25D164 transistor (which is actually 2SD1664). I dont think IG442K is correct either but havent yet figured out the correct part number (which is probably from ROHM or Panasonic, which are the main passive component suppliers on DMG boards). It also only describes the circuit used in the first two DCDC daughterboard versions, so it wont be 100 accurate for the later two versions. Continue this thread level 1 2 points 2 months ago In this case its just a very basic reverse polarity protection diode, so you can replace it with a similar schottky diode (something like 1A current 20V DC blocking voltage, although you could probably even go a bit lower if you wanted). ![]() PS. I strongly advise against buying the retrosix board. Im working on a technical review of it, and after doing some testing, it has become clear its not a suitable replacement. It doesnt output the correct voltages for the system, and the product page makes various claims that are not true. To me it looks like the electrical designer has no idea what theyre doing. ![]() Will you do a review on that as well Continue this thread level 1 Original Poster 1 point 2 months ago So a little backstory: I remember getting this DMG from a friend saying it doesnt work and figured I could use it for parts. Dmg Gameboy Parts Full Of MudThey never really told me what happened to it, but when I opened it up, it was freaking full of mud or something like that. Which is a damn shame coz the shell looks pretty great aside from the fact that the lens are missing. Also the diode that used to be there was so rusty, it literally fell off when I took the back mobo from the shell. I cant find it now, but Ill try to look for it and get a picture of it. Anyway I tried cleaning it as best as I could, and when I loaded it up with batteries, it didnt work. I figured I could test the front board with my other DMG and found that it works So now, Im trying to see if I could revive the back board by replacing the power board with retrosixs new one.
