Now Dave, are you ‘rat sure that those are positioned “vetically” ? No
by my being blind to your
situation , e.g., not having the unit in hand for an eyeball QSO, coul
you confirm that that
condition is maintained even when there is no power or batteries in th
unit.
(And even that thought process could be flawed in the respect o
retentive charge in the ua
current levels and low voltage levels still being maintained b
capacitive elements in the radio
for some time period after unpowering…..still adequate to effect
display action)
Also, was there any possibility of errant electrolyte seepage fro
defunt batteries involved.
My thinking would lean towards a contamination of a string of pixe
elements in the LCD array
to cause that effect. Or, my most common finding is a loss o
connectivity thru a connector to
the array.
This can usually be confirmed by powering up the display and enacting
moderate pressure to
the x-y planes of the displays front bezel assembly, hoping that wil
transfer enough movement
to the internal connector area to cause a corrective action in portion
of the display, thus tipping
you off as to a display connection being the problem. Don’t..rpt…DON’
exert pressure to
the threshold of fracturing your displays glass front face, however.
Also there might be the possibility of pressing on the rear of th
displays contact area via an
orange stick, wood dowel, etc., if access was obtained to inside th
receiver housing after a partial
disassembly. Should you find a corrective manner by pixels changing i
that prior probing procedure,
the most common cause of that condition is the manner of constructio
and the specific materiel
utilized in interfacing to the display. If you stored that unit in
heated environment (sun ravaged
car or storage building, etc)…..it is also more abject to failure
Should this exploratory action have
changed the display, get back to me and I’ll update you on what
usually find that fixes the situation.
