I once had an HDTV with a similar problem. If I turned it back on, it would make a loud BUZZ-BUZZ-Buzz noise for about twenty seconds before coming back on.
I can only guess that the problem is the TV drawing too much power from a circuit that can't support it. Do you have many electronics plugged into the same socket? Is the TV going into a splitter? Try isolating the connection and the TV might have better luck. No guarantees however.
If it's the same problem I had, then it will do this no matter what you hook up to it, as you seem to have at least partially discovered.
100% this tv problems it is the tv colors wheel it is defective require replacing.The loud tv buzzing noises sounds are the sounds came from the tv wharp colors wheel it is spinning out control wildly and off of it motor axis and by hitting it to the wall of it steel box holding it.The tv distorted colors pictures are came from out of the reflections of a badly worn out of the tv colors wheel.
You have one of two problems going on. Your fan is spinning at hitting the sides. Or your compressor is shot which seems to be more the problem and even though it is cold the humming sound is a warning for you that the compressor is shot and it is more affordable to replace the fridge then the compressor. Sometimes compressor can cost more then the fridge.
The TV usually hums when the backlight setting is too low. So turning
it up should get rid of the problem. To do this please follow these
1. Turn the TV on.
2. Press the Menu button on the remote, located right below the channel changing button.
3. Press the down direction button, located at the middle of the remote. Press that button until the backlight is highlighted.
4. Press the right direction button until the backlight is at 100.
5. Press the OK button and then the Exit button until you get back to your picture.
I have a 1.5 year old GE refrigerator and freezer. This unit had not given me any problems until 2 days ago when I constantly heard a loud buzzing sound coming from the freezer. I called GE and Best Buy (bought it there) and asked to troubleshoot this over the phone. They suggested sending a technician over for $100 just for the visit + labor + parts which could add up to hundreds of dollars. So, I researched the web and blogs like this. The answer to my problem was simple. Something that I placed inside the freezer was blocking the air circulation vent. So, I turned off the whole refridgerator and I removed everything from my freezer. For good measure I dislodged some ice and frost that had developed over the vent. I carefully put back everything into the freezer, but this time being careful not to block the vent. I turned on the power and voila! No more buzzing sound!!! I hope this works for you too.
