Would anyone know whether there is a group that is devoted to
appliance repair? If there is, I haven't been able to find it.
My dryer has been out for awhile now. I think the people here can
figure that one out and that I can fix it.
What has me bugged at the moment is my TV. I have it in a cabinet,
hooked together with my DVD player and VCR. (A satellite dish also,
although I don't think that is relevant.) They are all connected to
an uninterruptable power supply, which then goes to the wall.
Everything was working just fine.
Then the other night, bzzzt. They all went dead simultaneously.
The TV's picture turned to snow, and the other two components simply
stopped working altogether. I have fussed around with them, but I
can't make them work.
Could this have been a power surge? Are they now all trash?
I would have thought the UPS would have helped block any surge.
I've never seen anything like it. If they are trash, that's a fair
amount of expense.
Do you have a surge protector in line with your UPS? Based on your
description, it sounds as if your components are deadmeat. I think you
should take a good look at your homeowner's policy--component failures due
to power surges can be a covered item. You might need to have a diagnosis
to prove your claim.
No. I was mainly using the UPS as a multi-prong extension cord, but
for some reason I thought it included a surge protector somewhere in
its guts. Maybe I was wrong about that.
Still, it was odd. The DVD player and the VCR were not even turned
on at the time, and none of the other appliances in the house were
effected -- only those three. The lights didn't even flicker.
Another theory that crosses my mind has to do with some electrical
work that I had done recently. It could be that my friendly local
elctricians screwed up the wiring on that circuit somehow. (They
were just supposed to ground it.) I wasn't real impressed with them.
If that is the case, then I have an even larger problem.
The UPS contains equivalent surge protector circuit also
used in plug-in surge protectors. It claims to provide surge
protection. But then it forgets to mention which type of
surge. Like plug-in surge protectors, the UPS protects from a
type of surge that does not typically exist. It does not even
claim to protect from the type of surge that typically does
They sell on word association. You assume if it is called a
surge protector, then it must be surge protection. Wrong.
Surge protector and surge protection are two different
components of a surge protection 'system'. A surge protector
is only as effective as its earth ground. Since plug-in UPS
and and power strip surge protectors have all but no earth
ground, then they simply ignore these details - hoping you
will make erroneous assumptions.
MLD is making these assumptions. He does not even know that
UPS and power strip both contain same protector circuits - as
made so obvious because both are measures by same units -
joules. He also does not know this fundamental fact - a surge
protector is only as effective as its earth ground. What does
that UPS and power strip not mention to sell their grossly
overpriced, undersized, and ineffective products? Earthing.
No earth ground means no effective surge protection. Better
to not mention any of this. Discussions about earthing can
only result in reduced sales.
So many reasons could account for the damage. Clearly all
damage appears to be from a common source. And yes, even the
satellite dish cable is an important part of protection
'system'. Better to introduce the concepts of surge
protection in a previous discussion "Opinions on Surge
Protectors?" on 7 Jul 2003 in the newsgroup
With this, you can then appreciate what is really important
to ask about. Then there are many more details about UPS
protectors, warranties, protection for cables (which does not
require protectors), etc in "Power Surge" on 29 Sept 2003 in
the newsgroup alt.comp.hardware or
Bottom line - effective 'whole house' protector for AC
electric costs about $1 per protected appliance. How much for
that recommended power strip that is not even effective? And
phone lines already have such protectors installed free by the
telco. You will discover that widely held opinions about
surge protectors varies greatly from the well proven science.
Varies so greatly that many who recommend surge protectors are
simply promoting urban myths. They don't even understand the
most important concept in protection - a surge protector is
only as effective as its earth ground.

Be sure to give details including model number when you do.
You did check everything on another circuit known to be operable, and
they still did not work? Of course you did.
UPS is a generic term. A given UPS may or may not include features such
as surge protection and power conditioning (but many do). The manual for
your UPS will tell you what protection it gives you. No UPS, by the way,
will protect against all possible surges. Lightning hitting the pole
outside your house would be one example.
The problem may not have come through your power line, though. Anything
connected to the outside world (phone line, TV cable, antenna) may
transmit a surge into your home and connected equipment. Computer surge
protectors (not the cheapies!) often include a phone-line surge
arrestor, and you can buy them for your TV and run the coax through
there from wherever outside it came.
IF the equipment WAS protected thusly, the UPS may well have failed.
(They do, especially after a surge; it's a lot like an old-fashioned
fuse in that respect. Post-trauma, your surge protector should be
replaced.) Check your warranty, and you may find that the UPS
manufacturer has a claim program.
