Each time after I turn off my Tv it loses the position of all channels, so BBC 1 moves from channel 1 to channel 20, ITV 1 from channel 3 to channel 23 etc. I have tried re-setting the channels, but as soon as I turn it off, it loses the position, always as above. Also I note on the menu, the country of use changes from the UK, to Austria, which just happens to be the first country on the list ! Can anyone help so I don't have to reprogramme the Tv each time. Many Thanks Phil
I had the same problem. I replaced the EEPROM marked U33 (it's a 24C32 in a smd package) and the TV worked fine.
BEFORE replacing the EEPROM you have to go into the Service Menu (hold down VOL- and CH+ on the local command) and take a note of all the values, specially the R,G,B gain and R,G,B bias, in the "standard" picture mode as well as in the "Cold" picture as well as in the "Warm" picture mode.
(if you forgot to do this, here are my default values:
R gain: 434
G gain: 482
B gain: 484
R bias: 270
G bias: 270
B bias: 264
then you put the "Cold" image mode and set again those values, increasing the G bias to about 300 and the B bias to about 310.
then put the "Warm" image mode and set again those values, increasing the R bias to about 300 and the G bias to about 280)
The other values such as brightness, contrast etc, have to be left at 50.
I hope this solution will FixYa!
I had he same problem, Acer sent to me a technician who uploaded new firmware to the TV and in about 10 minutes the problem was solved.
Uploading the new firmware goes through a specific interface so unfortunately you can't do it yourself
I have the same pb with my Acer TV, I had 3 Acer laptop and each failed for different reasons! NEVER buy an ACER if you can help it!!!!!! ACER is cheap but never works longer than 18 months... ACER is worth crap!!!!!
This is a known issue - Acer have a firmware update that resolves this issue
