[Kenwood] TS-850 display problems.

[Clifford Conklin]

I have seen many posts on the TS-850 display problem.  I recently had to 
repair mine.
The only 470uf 16v cap(C16) on the display board had started leaking.  The 
leakage had also eaten
away the plate through hole.  I ended up replacing the cap with a "radio 
shack"  470uf 35v
axial lead cap. It is slightly larger so I folded it over on its side and 
hot melt glued it in place. I also repaired the missing circuit pad area 
with wire wrap wire.  As always use  good soldering iron.
I use an ESD safe variable temp iron with 6 tips for this type of work.

Refer to the service manual for B38-0350-15 lcd display unit.  Page 173 has 
a schematic for the
display, however it does not show C16.  Look at page 174 and you will find 
the C16 cap.

Good luck and 73's    KC2LXP
