blocked 12 - 24 V wire
Believe me, I have taken every wire that there is on the control box, sprayed it with contact cleaner and made sure that it is snugly fit into position. I also tried some of the cables on the BCU later. I couldn't find a damaged cable or one that was plugged improperly.
I'm thinking it's 1 of the following :
1) PSU for the controller
2) Main PSU
3) Control panel - maybe backlight failing - maybe entire panel
Mostly seems like PSU for the controller.
All the best friend. Keep us updated
Well I am still at it and right now I can't get any parts to try on.
I would like to ask this, however:
Has anyone used successfully a pair of off-the-shelf laptop RAM (that is of course the same gen, capacity and frequency as the original part) as the SO-DIMM sticks on the board that Ricoh calls the "motherboard"? The P/N for these sticks is B234 5563.
slimslob did mention that, on the controller at least, that it uses standard laptop memory but like I mentioned, I couldn't find what the exact spec for these are (honestly not terribly familiar with hardware before DDR2) but fortunately the RAM on the "motherboard" appears to be standard DDR SO-DIMM RAM.
Basically what I am asking is: If I match the RAM stick specs with a non-Ricoh RAM stick will it work or is there some sort of whitelist or DRM in place preventing me from using non-Ricoh parts? I am guessing there isn't but I honestly wouldn't be surprised if there was.
God knows how bad this has gotten with consumer electronics these days.
For one, Ricoh does not make the chips. They bulk purchase what are actually standard devices that have the original chip makers label still on them. You should be able to search the information on the labels and find exact matches for the device. Ricoh does spot test the devices. If they find defective devices they reject the entire batch.
