Electronics Repair Questions? Ask an Electronics Technician
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
This issue can come from a firmware glitch (hopefully) or a hardware failure (bad main board).
What you can try is to manually update the firmware, by downloading an update to your computer, and copying it over to the tv via a usb memory stick.
You can get the update file here: http://www.teac.com.au/engineering/LES5572F3D_5A30_1.rar
Download and extract that file, then save the fimrware file (MstarUpgrade.bin) to the root directory of a USB flash drive
Plug into usb2 on the tv
Turn on TV, at the same time keep tapping on remote’s volume(+) button until TV goes into firmware upgrading process.
Let me know if that helps.
I've sent an optional phone support offer at your request. If you prefer we can continue here in the chat format as well. Just let me know either way.
