If I am allowed to state my opinion - all these highly guessing facts from? a group whose technical knowledge is based
on answering multiple choice? questions to obtain a license lacks basic understanding how LCD is physically connected to the rest of
the circuit. On top of that NOBODY ever posted a picture of the LCD itself on top of the "mother" PCB.
BUT if you ever taken? apart ANY device with LCD - you would find out that there are NO SOLDER? CONNECTIONS.
The LCD "substrate" IS THE CONNECTOR and the physical adherence to the "motherboard" is all that is to?? it.
It is the nature , physics , on the LCD using very little current to operate ,? which? contributes
to the deterioration of the physical pressurized connection.
Now, that is my opinion and it does not change the fact that Yaesu goofed with the design.
My 857 was NEVER mobile , used few times on Field Day and it looks like live zoo - the stripes
come and go...soon to be replaced with a display "piggy backed" on to the RJ45
cable connecting the control head to the main PCB.
