Hi,

I just had a shop replace the power cord on a Sony KV-27FS100L tube TV.
(An in home service call.) The guy who did the repair said that the
connector on the replacement cord which connects to the board is not an
exact fit, but is the closest they had and will work. (And yes, the TV
does work). But because the connector is not as tight fitting as the
original, the repair guy said it is very important to have very good
strain relief to avoid tension on the cord. (I was not home when it was
repaired, this is what I was told by the person who was home.) However,
when I got home, I found that the repair guy did not put a strain relief
device in the hole where the cord is supposed to exit the TV. Instead,
he deliberately wedged the cord between where the bottom and back parts
of the case meet. This was his idea for strain relief. (The original
hole where the cord used to exit is now just an empty hole.)

Problem is, the wedged cord causes the case not to fit together
properly. The bottom is now uneven, so the TV sits a little bit crooked.
If you lift up the back of the TV, you can see the bottom bulging out on
one side, looking like it's going to break the plastic tab. My other
concern is that the cord is wedged between a protrusion of the bottom
and the back case, so the 100lbs of weight from this TV is now pinching
this cord. So my questions a

Is this safe? Can this pinch the cord enough to damage the internal
conductors or cord insulation? This TV literally weighs 100 pounds.

Is this really a stronger strain relief than just obtaining a strain
relief device for the hole the cord is supposed to exit through?

The shop was contacted, and asked if the proper replacement cord could
be obtained, even if we have to pay extra for the cord itself. (As long
as we are not charged for another service call or more labor.) The shop
called back after a day and said the exact replacement cord is no longer
available, and they don't have access to any. They said they'd get back
to us later, they haven't yet.

If the cord isn't available, should they at least be able to get a
strain relief device to fit the hole so the cord isn't wedged in between
the case parts? And would such a strain relief be strong enough even
though the connector on the board doesn't fit as tight as the original?

Thanks

Keep a class ABC fire extinguisher handy and you should be ok.
