Cricky, that is something that is not easy to answer. I am sure my choices change depending on my mood but if I had to I would pick... Space Odity Under Pressure Starman / changes or Oh I don't know!!!

Good luck and please let us know how you get on :)

I am not sure Martin is on the forums atm? so contact him via PM. Just to add to above I always add a dil socket so I do not need to solder the replacement IC in place AND the reason this IC fails in my opinion is that it is placed right next to the big transistor used as a voltage reg. This kicks out quite a bit of heat and can sometimes be found touching

Hi ok so the position detector is more likely fine then. Regarding the solenoid arms yes you need to pull them all off including the damper clean out with isopropyl and re-lube (singer oil or light machine oil is great NOT 3in1) and install. You might have to adjust the damper after relubing - please don't screw the screw down much below the top

First thing I would do, is get a properly rated bulb from member Martin (Dillen) as the one you have fitted might not be pulling quite enough juice for the circuit compromising zener / transistor etc. to see it - this circuit I describe does not relate directly to the light detector on the same arm... If after that the arm still shoots past the lead

I assume the sensor arm now lights up and you used the correct rating of lamp?

I am curious, do the micros fail in these often or do the faults tend to be less serious? [quote user="tournedos"] Replace the large electrolytics on the display board before deciding that you need another one. [/quote]

Not sure you could compare to the original unless you had a recently manufactured one to compare to the newly referbished one. I am sure they were every bit as good (if not better) when they were newly produced! [quote user="yachadm"] I just received an Axel-retipped MMC20. I chose the Shibata option. He redid the suspension as well. Beautiful

Why not measure across the diode on the working module? *edit - with power applied of course!

@auric I would personally say the opposite - very common for this style of pot to fail causing channel loss, and is fully repairable!
