Just ripped the gameboy apart and soldered the second resistor on top. So now the bigger sits on the smaller onekite wrote: ↑Sun Oct 22, 2017 1:33 pmThey are both 22ohm, so when put in parrallel (one on top of the other) will be 11ohmDamazeltov wrote: ↑Sun Oct 22, 2017 1:24 pmold one is still alive, found it on my shelf
so the old one is 22 ohm. how much was the supplied one together with the display?
Yeh the new boards just have a solder jumper so it's a lot easier![]()
What resistor is on the new board? Also 11 Ohm? Is it possible to install a 10ohm instead of 11 and get the display even brighter?kite wrote: ↑Sun Oct 22, 2017 1:33 pmThey are both 22ohm, so when put in parrallel (one on top of the other) will be 11ohmDamazeltov wrote: ↑Sun Oct 22, 2017 1:24 pmold one is still alive, found it on my shelf

Yes sure, just one transistor with 10 ohm.kite wrote: ↑Mon Oct 23, 2017 12:19 pmNew boards have the same config. You could go to 10ohm, the voltage at the LED (the right side of the diode by the connector) according to the datasheet should be MAX 21v, and they recomend 19.2v. On my board it reads 19.5v so you could reduce the resistance slightly (TOTAL 10ohm, not just adding a 10ohm ONTOP) and check it's at 21v or below and that should be fineDamazeltov wrote: ↑Mon Oct 23, 2017 11:42 amWhat resistor is on the new board?
