Hold down the OK key for a longer time. It can take up to 1 minute.

Try a smaller capacity usb drive (2.0). Format the usb stick and copy paste 5 files.

I can try and fudge a smaller capacity SD card in a USB adapter but why would Hitachi send me a USB stick that wouldn't work because it is too big for their TV?

I tried that with the remote OK instead of the button on the back of the TV but no change. The flash drive sent to me by Hitachi with appropriate files looks like the picture. Any more suggestions?

If it is Vestel:
1. format a stick (preferably 4-8 Gb) with FAT32
2. unzip and put the files directly on the stick
3. Unplug the TV
4. insert the stick in the tv. Preferably usb next to CI card
5. press and hold the OK key on the remote control
6. Plug in the TV.
7. The left LED on the TV will flash slowly at first and, after a few seconds, faster
8. release the ok key
9. wait for it to finish. It can take 3-10 minutes

I have a USB from Hitachi with the appropriate files that reads on a computer. When they first sent me the USB I tried it in both USB ports and held the Button on the back of the TV but it didn't change the LED blinking.
It is still the same now but with the back of the TV off I can hear a faint hiss from the power supply that seems to tick as if the switching part of the PSU is on is this normal? I would have thought the standby or even flashing LED wouldn't start any of the heavy supply running or is the blinking LED state a turned on PSU state?

normally first format drive as fat 32 . but that should have been done .

Your tv its probably a vestel. You need to flash the correct firmware for your tv using a usb stick. You just throw a bunch of files into the usb stick, a working remote control and you are good to go. A blinking led light dosent necessarily mean that its a bad firmware, but a firmware update solves the problem 90% of the time.

I couldn't find any other thread that matches my TV problem but have been told it is a common fault. The fault is a flashing LED as if it is in upgrade mode that happens after a few seconds and stays forever. I can't remember all the tricks that have been tried like holding the select button when powering on but nothing worked. The shop sent me a flash drive to plug in a USB port but that did nothing either and they said it was dead which is disgusting for a piece of solid state electronics. I took the back off eventually after removing 34 screws to check for blown caps but everything looks new as you would expect for only 18 months use. The board is a Vestel 17MB100 and I think it died when it was doing an upgrade because the TV screen came up then it checked for an upgrade turned off the screen and stayed with the flashing LED for over half an hour.
I have some questions to start.
1) Is the flash drive meant to be bootable (mine isn't) or just a bunch of files?
2) Can a serial lead be plugged in to see a boot up log like some other TVs?
3) Any ideas on how to fix it or find out what is wrong?
