Hmm...sorry but I understood about 20% of the above post - got a bit too
technical for me... I am the OP here is the original post:
I got a good quality one to four video splitter so tonight I got up to the
attic and disconnected the old splitter. Nothing unusual.
Then I connect the new cable IN, then one by one I connect the cable OUT.
When I get to the last one I felt a strong tinkling on my finger, you know
when you rub your shoe on the carpet a few times and go touch a metal
railing? Yes that feeling...I dropped the splitter. Is it static? I don't
know. So I touched the splitter, which at that time has the one IN cable
and three OUT cables connected, and nothing, it's OK. Then I let go of the
splitter and touch the last coax cable connector - nothing...so I touched
the splitter with my left hand and the remaining cable connector with my
right hand, yes I feel it again. What is going on?
I then left the attic and when to the other end of that cable, which was at
the time plugged into a VCR, which in turn was connected to the TV and they
were running. I unplugged the connector on this end, went back to the attic
and no more problem. So I hooked the last connector up.
Then I came back down and put the cable connector back to the VCR.
What caused this? Does this mean I have an electrical problem with that TV
Here are some additional tests I did afterwards:
Well that does not compute either. Because I have the cable feed coming in
from the outside and into the splitter. If I hold onto the outside cable
and splitter, I do not feel this mild voltage spike. Now this splitter
splits into four cables which connects to four TVs. Let's say we have cable
A, B, C, D.
I take cable A, and connect to splitter. Nothing, no voltage. Repeat for
cable B, nothing. Repeat for cable C, nothing. Now I go grab the last
cable, cable D, and I feel the voltage. I only feel it when I have outside
cable + splitter in one hand and cable D in another. I let go of cable D,
nothing. I let go of the splitter and only hold cable D, nothing either.
Does this mean it might not be the outside cable grounding since cable A, B,
C do not have this problem?
Now I go to the other end of cable D which is connected to the VCR which
then feeds to the TV. I disconnected that end. Go back to the attic.
Touch both the splitter and cable D. Nothing. Then I went back down and
connect cable D directly to the TV bypassing the VCR player, then back to
the attic and try again, nothing. Then I wired it back to the VCR, repeat -
yes I feel the voltage.
Does this experiment conclude the problem is VCR player?
