RetroStone boot problem identified
Posted: Wed 10 Oct 2018 16:16
Hey guys,
I just found the reason for the specific boot problem all retrostone are having sometimes.
It usually is as follow :
- 10-20% of time the unit will stay on blue/white LCD forever
- 90-80% of time the unit boot OK.
The good news is that I found the issue and that future retrostones will be corrected. The bad news is that it's a hardware issue and to fix it you need to remove a resistor. (same as audio filter fix).
The resistor to remove is R23 just under the SD card reader. It should be removed and replaced with solder. Or you can just drop a ball of solder on top of the resistor, no need to remove the resistor. Or as someone suggest after you can just use conductive glue : put a blob of glue on the resistor and let it dry.
I will post a video asap.
Very sorry about this additional imperfection
