...running the TV by itself not connected to anything else and with the DVD player and AV units turned off? What was the result? Did you repeat the experiment with just the DVD player connected? What was the result? Did you try experiment 2 with the DVD player powered directly from the mains, not in the surge protector? What was the result? Did you try experiments 2 & 3 with the AV units?
If you still get the problem with the TV alone in the surge protector, it would be one of those two. I'm not sure how stable the French electricity supply is (not very from your comments) but could the surge protector be responding to a spike from the line voltage and doing its thing to protect the attached equipment?
What sort of voltage converter do you have, a transformer (good) or a switcher (not so good)? Could feedback from it be triggering the surge protector? I vaguely recall some years ago someone telling me that running voltage converters through a UPS wasn't a good idea but I can't remember why and don't know if that also applies to surge protectors.
Incidentally, I have an LG TV, not OLED, and occasionally, it will just switch to standby - never comes back on by itself. I think it's a stray radio signal it's picking up because it does respond to the remote application on my LG mobile phone. Oddly, always about the same time on a Tuesday evening!
First of all, I think my problem with my LG OLED 65C7V television is not the fault of the TV. It's a new TV, not even two weeks old.
Second, I live in France, a country with a voltage different from the USA and Canada. I moved here a few months ago. When I made the move, I brought along my Marantz SR 5010 AV receiver and a Velodyne sub-woofer. After all, they're not cheap and I didn't want to have to buy them again.
Third, to accomodate the receiver and sub-woofer to the Frech voltage, I bought a Diamond Series Type 5 voltage converter. It is capable of handling twice the watts that these two components draw.
And fourth, to play European and American CDs and movies, I purchased a region free Samsung Blu-Ray player from 220-Electronics.
So here's the set-up. The LG OLEDC TV and the Samsung region free player are plugged directly into the French electrical system via a surge protector (that I also bought here in France). The Marantz AV receiver is correctly plugged into the voltage converted, which is then plugged into the surge protector. HDMI cables connect the Samsung to the Marantz AV receiver and the receiver to the TV.
When I watch a movie on the Samsung or when I use the Samsung to stream Netflix or Amazon prime, the LG will periodically go on and off, sometimes way to frequently to make the experience enjoyable. My question is where lies the problem? I believe the TV is working fine, as it is less than two weeks old. The HDMI cables are also working fine. I think the problem may lie with my Marantz or with the converter, which sit right next to each other on the TV table.
To get the TV functioning again, I just wait a few seconds till it comes on by itself. Sometimes that doesn't happen and the TV screen says all connection has been lost. Then I turn the receiver off and back on That seems to solve the problem, that is until the reception clicks off again..
Does anyone have any idea what is causiong my problem and, if so, how do I fix it? Thank you in advance. And I apologize that this post is so long.
