After you awapped tvs and the problem did not reoccur, did you go back
to the original location for each set, or did you leave them swapped?
That is crucial to know before we make further prognoses.

I have an intermittent static problem on one tv in my house. When
watching cable short and annoying blasts of video and audio
static occur repeatedly until I give trying to watch. Or
ometimes it only happens once a day and will be days before it
happens again. Two diffent cable tech say it is the tv. The
other tv in the house does not have this problem. I finally
switched our second tv with the one that has the problem and the
static has not happened since.

The tv with the problem is a 31" Toshiba. When playing dvd's
(using either the svid or composite video input) the image is
perfect the static never intrudes.

If the problem was in that line (wiring or connections) then I
believe the problem would occur on whatever tv was in use in that
room. I am left to believe that the problem must be in the cable
ready portion of the tv. Anyone know any common problems or
thing I should check on the cable ready board??

I can check and replace electronics, I work on pinball machines.
But I have schematics and know the common pinball aliments.

Thanks,
Dug


My guess would be connections as others have posted. Whether at
the splitter or in the set. Try testing the set at a neighbors
house. If it is the set and you want to try your hand at fixing it
then get a bright light and a magnifying glass and look for cracks
or dark spots in the solder connections at the tuner. Usually it
will be a part that runs warm and is moving back and forth when
the set is on or off or maybe a single sided board without enough
solder. Just heat up the connection and run some solder into any
connection that looks suspicious. Also check for discolored
connections. They could be the cause too but no guarantee. Please
make sure to unplug the TV not just turn it off just to be safe...
Another idea would be to post this on sci.electronics.repair and
make sure to leave the full model number...There are some
excellent techs over there and you might just have a well known
bug with an easy fix.....good luck...



Note that CRT TVs have large capacitors with large voltages that
hold their charge for a long time.

An unplugged TV is not necessarily safe...

The OP might not be the only one reading this thread, so I felt it
wouldn't hurt to mention it.

I have had a couple of nasty shocks from unplugged TVs, but I did
survive - perhaps :)

if you know what the tuner looks like, and you are not an expert,
don't open the tuner...just squeeze the cover of the tuner a few times
and see if that fixes the problem for a few weeks,,, if it does then
you know you need to get a tech to open the tuner and clean the ground
contacts to the cover...

I swapped in a different tv. I did not carry the 31" downstairs. The
new set did not have any static at any time.

I tried what electricitym man suggested: reconnecting the old tv and
using the vcr tuner. And experienced 2+ days of no static whatsoever.
But the static has returned. To be very clear the connection is
wall-digital box-vcr (vcr on, vcr on vcr not tv, set to channel 4)-tv
channel 4. And I am using coaxial cable all the way trough. I believe
electricitym had intended that I use the composite output from the vcr
and bypass the tv's coax/tuner completely. I will do that as a last
resort but the tv is a bit older and only has coax and
s-video/composite inputs.

I will next try to open the unit and inspect grounds and soder joints.

I won't be able to get to it until sunday, thanks to everyone for their
input.
