I read in another thread about someone who replaced the LCD in a Raymarine unit, saying that the LCD snapped into a socket in the unit.
My thought is to replace the display with a new one (about $500) and investigate whether the LCD can be replaced. The repaired unit would make a good repeater unit located at the nav station.
My ST60 depth
faded out last year. It could have been speeded up by my ex boat partner leaving the battery/instruments on and putting the cover on the unit. I think heat was/is a bad thing for lcds.
I was fortunate to pick up a used replacement on the classifieds here. I disassembled the failed unit but getting just the lcd unit off the electronics
motherboard was a non starter for me.
In regards to OP power issues this looks like an intermittent fault. Very tough to troubleshoot. I would start with removing and cleaning
every connection. The seatalk plugs (male to female) could also be loose. I had a loose plug
on the mast
fitting. As a temp repair until I could get a new plug
I rolled up a small amount of tin foil and inserted in the female sockets so the male pin would make good contact.
If your units are wired in seatlk series as the raymarine install manual allows, using seatalk cables
the "problem" with that is as a series connection an upstream fault affects all the units downstream, so I would suspect an interemittent closer to the source. When cleaning all the connections do not forget the connections starting right at the dc bus.
However I suspect a seatalk cable connection as you have intermittent power "and" data faults.
A "tiny" file can also be used on the female socket (or a socket brush) to clean corrosion
. Work methodically and slowly and clean and secure all connections. You will eventually find it.
Also keep an eye out on craigslist and the classifieds. I was extremely lucky to pick up about $1200 worth of instrumentation for a few hundred dollars.
