I had quite an issue with my 1998 Honda Civic HX, told me the oxygen sensor was lazy, even for a new sensor. Turned out that the ECM needed more recent firmware, but an update was not possible. Ended up getting a replacement ECM which cured the problem.
I had this issue; I ended up buying a second hand speedometer and swapping out the circuit board, that way I kept the original mileage. Has worked great ever since.
That high resolution mod is real nice, its almost a pity I don't have an old Intel iMac to work on. https://realmacmods.com/product/unimac-v4-kit-with-hd-screen/
This is all amazing stuff, that Apple changed the code on the LCDs self-identifying EEPROM when moving to the Intel base. Can anyone tell me which chip on the G5 iMac/Intel iMac LCD is the EEPROM chip?
Radio-Shack have a very nice iron with a hole in the tip; I found this makes working on the G5 iMac board much easier, as it heats all round the lead. http://www.radioshack.com/product/index.... I recently re-capped a G5 iMac board, and it went very smoothly thanks to this $12 iron. Replacing the capacitors can be done without having to clear the holes, by cutting the leads short so they can be pushed in with a little pressure as one heats from the other side.
Best to open up the power supply and take a look at the capacitors there, I'd say the power supply is more likely to fail than the motherboard and a bad supply will put out ripple the mother board will try and smooth, so yes, conversely, the mother board probably helps the power supply out.
Good to know, I may just fix the 1.8GHz unit and leave the 1.6GHz units alone. I am getting to like the Samxon capacitors and will try those. http://www.capsmod.net/caps/ bigpope.samxon@gmail.com has the caps for the iMac G5 but they are not on the list, and the price is a bit high.
