Flaky Inspra LCD monitor/TV

[Joel Kolstad]

I have an Inspra brand LCD monitor/TV that's always OK when you first power it
on, but over time (some tens of minutes) it'll stop responding to its control
buttons. Typically the video input will continue to be displayed for
....awhile... more (sometimes up to an hour), but eventually it flakes out as
well (display freezes, ends up with garbage characters through it, etc.). The
'power' button is just as likely to be ignored as the other buttons are
(volume, menu, select, etc.). It's been slowly getting worse, working for
less and less time before misbehaving.

As far as I can tell, the model number is 2K702M. It's the one on the left at
this web page: http://www.eteckusa.com/inspra.html

I want to believe this could be something as simple as some bad solder joints
that tend to warm up and then no longer make proper contact with the pins of
some component. Anyone think this is likely? Or something else?

I'd love to find a schematic (or even the manufacturer's web site!) for this
thing...

Thanks,
---Joel Kolstad

Somewhat amusingly, it appears that a guy on eBay has one of these monitors
with similar problems! -->

Most likely there are components that have become heat sensitive. This
can be serviced by someone who is properly equiped and trained to this
type of work.

As for any service manuals or factory parts, these are not available
from the manufacture. If the monitor requires any propriotory parts,
there are non available.

During the warrenty period, these monitors are normaly serviced at the
modular level by their authorised service reps. They change the
defective module, and then do the re-calibration to match it. After
warranty, these models are considered throw-aways.
