TV not turning on

I have a UMC TV that keeps scanning every time I turn it on. It says not to turn it off and let the scanning finish, but then once it gets to 100%, it just starts again from 0%. Any ideas on what's wrong with it, how I can fix it, or how to set it back to factory settings?

Hi Ziggy. Firmware issue on your main AV board my friend. I have heard of this with UMCs before.
You could try a factory reset. If that doesn't work, you could try updating the firmware with a usb flash drive - you would have to find the firmware for your particular model from the manufacturer's website (assuming they have one).
If that doesn't work:
Obviously, if it is under warranty contact the seller or the manufacturer and they should sort it out for you.
If it is out of warranty then you could try replacing your AV board. Spare parts from TVs damaged in transit or used parts are often listed on eBay and other specialist TV parts websites.
You would have to open the back - remember to UNPLUG IT FIRST - and you're looking for the big circuit board that has all the video inputs in. Find the part number on it and search it on eBay or a site like www.flattvparts.co.uk - replace the board and (assuming they sent you a working board) that should solve your issue.

How do I input my sanyo television and make it stop trying to search for channels?


Have you tried keeping it disconnected for several minutes ? So when you turn it on it automatically start to scan, but what happens if you press the menu buttons while its scanning ? If you are able to get to the menus, try to change the scanning settings. Also have you tried letting it finish scanning ? Maybe it only wants to do it once.

Hi, Can any one please shed any light on my problem, When I switch the tv on it says DO NOT POWER OFF and under that SCAN it scans upto 100% then scans again upto 100% and again and again does not stop...


Try a hard reset by unplugging the tv while it is turned on. Then push and hold the power button for a few minutes to drain the electronics and memory of all. Then release button and replug back into outlet and then turn on to see if that has done the trick. If that does not work you can contact tech services for a hidden code to restore unit to factory defaults.

Stuck on scan


It may be that the power cut was the result of a power surge. It may be that the outage has caused damage to the components of
your tv.If it does not return to normal you will need to get a very GOOD technician to diagnose the fault. It may be that the tv can be repaired, it may not ...but eirher way I would think about seeing whether the power company is liable for the damage.
The fault is almost certainly something that needs to be checked out by a pro

My UMC tv x216/17c-gb-ftcd-uk does not turn on with power applied. How can I test to find the problem


Hi boys,
Hope you are still here. :)
My tv UMC x216/17b gb-ftcd-uk 21.6" doesn't turn on anymore. No LED light but consecutive clicks on DVD area.
The power supply is working (12V), I unplugged the backlight screen board and the DVD unit but still not working.
So I decided to replace the main AV board.
I found on eBay the board with the same code B.LT712C 8373 but for UMC 23" or other makers with different screen size.
Do you think this board will gonna fit on my UMC 21.6" as long as is the same part code ?

Thanks,
G.

My UMC 22" LCD TV


Please don't just keep trying random fixes until you've spent more money than it's worth. Research the problem online, and if that fails, there are still some good TV repairmen out there, but it may take a lot of digging.

How do you turn off the progressive scan


I own this model and do have the manual; however, standard AV and S-Video connections do not transfer progressive scan video images. If you hookup a progressive scan output to a non-progressive scan TV input, you will not get an image, so it is probably the way you have your machine connected to your TV that is the problem. If you are trying to watch regular TV through your machine, you will probably need to use a standard Coaxial Cable. I hope this helps.
