Konka K2001UM service

[David Nebenzahl]

Just got a working Konka TV (left in the street, literally). Works OK,
except that the picture's a bit dimmer than I think it should be, even
with the brightness cranked up all the way (60 on the on-screen
display), also with maximum contrast.

Is there any internal adjustment I can make to get a little more punch
in the picture? Or is it already maxed out, and what I get is what I get?

Before you post dire warnings, I know all about working around high
voltages, etc., etc. I promise to be very, very careful. The last time I
worked on a tube, I was able to bring a Sony Trinitron computer monitor
back to life by adjusting the focus.

Any help appreciated.

Someone recently posted a repair tip to aus.electronics that may be of
help.

I think that's why they left the son of a bitch out in the street in
the first place?

Could be. It's certainly watchable; I'm not too picky about TVs, as I
consider it pretty much throw-away low-level entertainment (even if I do
watch way too much of it!), and it's certainly better than the set it
replaced, an old Panasonic that was given to me several years ago.

I have just enough interest in this problem to eventually pop off the
back of the set and try to find a trimmer pot to adjust (only if
labeled; I'm not a "ghost tweaker" type). Was hoping that maybe someone
else had been down this road before.
