Purpose of device???

[Ken]

I have a Zenith SR2568 TV that has a device near where the power cord
connects to the PWB. It is thin (1/4"), and is something like 1 1/2h x
2 inches wide. It appears to contain brass inside the plastic cover
with gaps of about 1/8 inch, each terminal connecting to line, neutral,
and chassis ground. From what I see, it looks like it might be a spark
gap of sorts for line surges since it is connected to the inputs.

Is that what this is, and is it REALLY effective?? I would think the
voltage on the line would be so great everything would be destroyed by
the time the gap was crossed? Thanks.

I do not currently have any problems with the set, just curious.

I`m not sure but think that is an attempt at a lightning arrestor .

a pic would help, the above is too ambiguous

Sorry, I can't help with a picture. From where it is at, I think Ken
G. is correct. I just did not think such a spark gap in the A/C power
input would do much to protect the rest of the TV. My purpose was to
see if someone who regularly worked on TV's was familiar with such a
device.

If it had capacitors inside it would be less unusual.

I have seen many of those . As i remember it has a plastic cover with
slots to see into it . I suppose it may stop some lightning strikes but
not all . I have seen several lightning hit tv sets and in some it dont
stop for no one .. fried foils all over the place and maybe an ic chip
or two blown its top . Idaho has some pretty good lightning storms .

That sounds exactly like what I was trying to describe. I was
surprised that it wasn't completely covered somehow, even though it DOES
say HOT around the device and it is connected to line voltage.
