I have a TI monitor that has a power cord that is becoming sticky and gummy and I'm
looking at what to do with it. I figure the best solution is to probably see about
replacing it with a new one. Has anyone ever looked at this monitor and the cord
connection? Have any info on it? How difficult it might be to replace it? I haven't
been able to find any doc or anything searching online but may just not be using the right
keywords. Any other suggestions on dealing with the cord besides replacing it? Wrap it in
something I suppose... Thanks in advance. David Williams www.trailingedge.com

Once the plastic starts breaking down I haven't found anything permanent.
Some are breaking down slow enough that cleaning lasts for a couple years.
I go though my various cleaners/solvents until I get to one strong enough to
clean it up without too much damage. The ones for removing gummy adhesive
remover seem to work OK. A mild abrasive cleaning pad or cleaner can also help
since sometimes you need to remove the surface plastic layer to get to more
stable plastic. Aggressive solvents will also do that but I have trouble
controlling them.
Not familiar with 99/4a monitors to comment on replacing cord.

You can expect that eventually, the jacket on the cord will begin
cracking as the loss of plasticizer progresses.
A somewhat more pragmatic approach, short of replacement, is to encase
the the cord in split wire loom. Looks a little clumsy, but will keep
the sticky stuff from fouling anything else.
FWIW

Yeah I figured cleaning of one sort or another would only delay the
inevitable. I can open it up and look at the cord attachment but thought
I'd see if anyone knew or had anything showing it before I went to that
trouble. My other thought was I have various cable wrap that I could
encase it in as a quick easy way to deal with it.
Thanks.

Never had one of these to take apart and don't see a service manual
right off, but I'm assuming you have the 10" PHA4100 model, so the
connection will likely be whatever Matsushita/Panasonic used in TV's
that era. There was a 13" model PHA4000 that is a modified Zenith TV,
but those were pretty uncommon, only sold with the /4 (not 4A) until TI
got FCC approval for their RF modulator, which allowed most of us to
use a standard TV. The 4100 has a cleaner picture, though.

I have both a TI one and a Panasonic one, both identical short of the
badge and case color and both have the gummy/sticky power cord.
The TI one isn't here with me at the moment but the Panasonic one is
marked model CT-160. Find them for sale online but not the manual yet.
Starting to lean towards just using the mesh cable wrap I have on it.
