Re: olevia 37 turning off for no particular reason
I suspect that the main power supply is trying to self-destruct; what you describe could be the switching power supply struggling to stay up and running.
It isn't the cable company's problem.
FYI: Olevia has declared bankruptcy so you may not be able to get any help from them.

When you have strange problem like this, power supply module will be the first thing to check for steady DC. Since this company is no longer around and parts are getting hard to come by, the repair shop will not even try to do component level repair on it due to time consuming process and no schmatic available.
There may be not much you can do.
This the common problem for Olevia TV, open up the back cover, locate the power supply board, look for the electolytic capacitors top that is slightly domed, replace them, they usually 1 or 4 that is bad, buy your replacement's at Radio Shack
It sounds like a logic issue. The only way to fix it is by replacing the main board. If it is less than a year old, then it should be covered by the standard manufacture's warranty. Olevia has since gone out of business but I would still try to contact a representative to get it repaired under warranty.
I think I have solved the problem. I dusted the tv completely. Then took the cable box and with a hair dryer in the cool setting blew out the interior circuits to try to remove all dust. Turned the set on no more crackling. Thanks for the posting.
I have a 32'' olevia 232v hdtv. I had a similar problem where the tv stays on less and less as you use it longer and it gets warmer. I called customer service and they explained that its most likely a problem with it is doesnt have enough power to run well. They said turn the TV off, then hit the master turn off switch in the lower back of the tv, then unplug everything from the TV, then unplug everything from the wall. Then after 3 or 4 hours, plug all back in and try again. Then they said if i still have a problem, call customer service at 1 866 9 olevia
