LXI TV

[The Doctor]

27 " LXI, 15 years old. Suddenly not responsive to video controls
(birghtness, contrast, etc). The sliders move on the menu screen but
the picture does not adjust. Looks like everthing has gone to a
maxxed out setting.

Len -

What is your level of experience?

I am not a TV tech per se, however I do have formal education in EE
and a fair amount of experience.

Retrace in pix? Yes.

Any measurements taken?

No. The only test equipment I own is a Fluke multimeter.

This unit is one of several in the establishment where I work. I was
hoping that the symptoms might point to something specific - perhaps
some kind of control board fault. Just trying to save the boss some
money. If you think it could be something like an open resistor or
diode I could probably track it down. As I said, I'm not a TV tech so
don't lose me in the technical jargon. OTOH, if it isn't worth it...

Regards - tony
