Thanks m-heat......I have the Dynex TV connected as a monitor to my desktop computer.....and oddly, now that I have accidentally set the TV to "burn in mode" in the SM, instead of the monitor shutting down after prescribed time and going to a blank black screen and eventually shutting off, it oddly goes from a full green to a red screen to a blue screen to a white screen and then finally to a black screen and repeats the color sequence all over indefinitely staying on each color for about 5 seconds. I tried to access the menu while it was on the white screen but it didn't seem to work.....
I know sometimes if you unplug the TV and press and hold a certain button as you are plugging it back in, depending on the brand, it will re-set to factory shipped settings.
I have certainly learned a valuable lesson here...never ever modify anything in the SM unless you know what you are doing !
Thanks again m-heat for your courtesy in attempting to help me out. If you can think of anything else, I'm all ears.
P.S. I am currently in communication with the Dynex support via email. They don't understand the issue...they claim there is no "burn in mode" in the menu. I did confess to Dynex support that I went into the SM and they still can't understand what I did. I am trying to get the original factory firmware for this Dynex DX-32E150A11 32" LED but they claim it will not resolve the issue. They claim that I can unplug for 10 minutes then when plugging in again, press and hold the power button for about 40 seconds then release and that should "recycle" or reset the TV......this does not work.....as soon as I plug it in again, the TV immediately comes right on without any button or remote intervention from the user!
