Well that was a little disappointing no responses.
So I decided to do a little detective work on the module.
Set up a switch system to illuminate the display while at
the same time shorting out what I suspected to be
the offending part. ( LDR circled in pic below) And Hey presto
full brightness.
Actually to bright now. So I took a reading across the
contacts with my meter of 304 ohms both in the dark and
with the lights on even with a torch shining straight at it,
no change. So I'm thinking it's US.
So just before I go rummaging in my bits for a replacement.
Does anyone out there know what it should read and are these
soldered or epoxied on?
Again thanks in advance.
Pete
