Power Savings....I prefer OFF. But LOW is the 2nd one I prefer. If you accidently turn your Cable Box OFF...and your TV goes black, but it's ON...then it auto-shuts off the TV set saving you money.
However a BAD Cable connection to your TV set can cause your TV to shut down.
That's rare...but not impossible either.
This type of cable is Notorious for slowly disconnecting over time --
But I would expect you to start seeing the picture go black while watching it and a "No Signal" banner to pop up on your TV set too.
TV sets that WORK FINE after being turned on a dozen times....that can make your TV look like it's OK.
However....go to bed tonight, wake up in the morning, TV Cools Down.....
A TV can give you problems when it's COLD.
I would keep my eye on it in the morning, because if you have problems like you described....it's going to fail MORE in the morning if it's not been on for hours.
One thing.....If you HAVE been pulling the LEFT or RIGHT side of your TV out, and it suddenly WORKS afterwards....report that back to me.
That's where your BALANCERS are located. On the left/right ends.
If you have any questions, just ask
Tips are greatly appreciated !
