Default quirky lcd?

hello. im not sure if this is the right group for this question and i am
no eletcronics whiz so plz bear with my limited terminology.

i bought a modestly priced stereo. it has 4 services: lp player, radio,
cassette player and cd player.

some of the elements on the liquid crustal display stop showing up. it
appears to be the same display elements ( two from the third character
set from the left) regardless of what service is being used, so i dont
think it can be a single flex cable

a little thump on the unit restores the character elements for awhile,
then the problem returns later, probably from being aggravated by the
soundwaves.

is this something that should be/can be repaired by a local (small town)
electronics repair company? or would the cost outweigh the benefits of
the repair?

Without taking a look, it's hard to say. If the display really is an LCD (
as opposed to a VFD ) then the problem could either be bad joints where the
display panel's pins solder into the pcb, or bad connections where the pins
are made off to the panel. The former is readily and cheaply repairable -
assuming that not too much dismantling has to be done to get at the front
panel pcb.

The latter is not repairable, except by replacement of the LCD panel, which
would probably be cost-prohibitive, if even available as a spare.

If the repair company that you are thinking of is reputable, they will
almost certainly be able to look into the problem for a fixed inspection
fee, and if it is just bad joints, fix it at the same time. If it is
determined to be more serious, then you're only a small amount of money
down.
