Does the hum go away when you mute or turn down the sound completely? If it does then the issue might be one of the sources connected to it IE: DVD, Cable Box, Satellite receiver..

Problem with Olevia 226-T12 firmware install


the only thing is to keep trying it but you might want to leave the television off over night and then try it the next day.. also try doing the firmware on a 1G or less thumb drive...if the television is still not grabbing the firmware then it sounds like the television will need to get service... this means the television's main-board will need to be flashed.

Since the Manuf. of Olevia is out of buss the only company at this time that has the tool and parts to repair the television will be the 3rd party repair center called Amergence Technology ( 866-965-3842)

Firmware update Failed


I had the same problem with my olevia 242-T11. I flashed it with the wrong firmware and the TV would not even turn on. The blue LED light would still light up and my PC would still recognize a connection when i hooked it up to the USB cable connected to the TV.

I was fortunate to download the appropriate software. The software is called MTK_DownLoad1.exe. I know this is the correct software to use for Olevia 242-T11 and Olevia 237T. I do not know if this will work with other models.

Here is the link to the MTK_DownLoad1.exe
http://rapidshare.com/files/17475900...load1.zip.html

You will also need to install the USB to Serial driver before you are able to use the MTK Download Utility. The USB Driver is located at
http://rapidshare.com/files/17475900...river.zip.html


BE SURE ONLY TO UPDATE YOUR TV WITH THE CORRECT SOFTWARE OR YOU WILL BRICK IT. I was lucky enough to recover my TV and finally able to upgrade it to the correct firmware but my TV was non functional for about a week and this has been a huge headache and if i could go back in time i would definitely not do it so please ask yourself if its even worth it risking upgrading the firmware of a TV who parent company is reorganizing after declaring bankruptcy.

If you still want to do this, here are the firmwares for all the various Olevia models.

I hope this helps all the people who need to recover / unbrick their Olevia TV's. If the links are down or you need any help please ask for help in avsforums. My id is sammykismail on avsforums and i will try my best to help you.
