Try this: with TV in standby keep pressed cursor up on the remote then press Power key on the front panel, this will make an hard reset. If this doesnt work, try enter service mode: Display key, 5, Vol+, Power, this with remote, Display is the key that represents an old 4:3 empty screen, then press 8, Mute, 0, this makes the hard reset, to exit turn off tv.

Try to pick up different USB flash (old, not large).

Re: Sony kdl 40ex720 firmware update

I tried an old one with 1gb even an Sony card reader with small SD cards.

Re: Sony kdl 40ex720 firmware update

Try to look for and select different USB flash drives, it won’t make sense that you found one on 1Gb, you need different manufacturers (with old controllers inside) so that the TV can determine.

Re: Sony kdl 40ex720 firmware update

If I find and buy the same board from a 40ince tv do I have to do the update or its plugsplay?

Re: Sony kdl 40ex720 firmware update

Yes, you will also need to update (they have a main + T-con binding), then it’s easier for you to buy a native main + T-con kit the same as yours with the same matrix.

Re: Sony kdl 40ex720 firmware update

I understand but its an extra cost and I don't think that worth the money..

[lotas]

Re: Sony kdl 40ex720 firmware update

Yes, then it's easier to pick up a usb flash drive with which to pick up the update.

Re: Sony kdl 40ex720 firmware update

I don't know sir I think its not the problem with the flash drives but maybe the board i bought its faulty

Re: Sony kdl 40ex720 firmware update

Rather, the board is working, since it needs to be updated, but choosing the right usb flash is problematic for older TV models.

Re: Sony kdl 40ex720 firmware update

Before each attempt to update, you need to unplug the TV from the outlet and wait 20-30 seconds, then just turn on the power with the USB flash drive inserted.

Describe which local keys you have.. or try different combinations when in standby

Re: Sony kdl 40ex720 firmware update

Look for flash drives from the years when your TV was released, I have a very old Sony flash drive at 512Mb and never had a problem with updating old TVs.
Also, try cleaning the USB contacts on the TV itself (when unplugged) and on the flash drive itself.
