TV losing its channel memory

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've also got a AL2671W with the problem, that all the channel settings faal back to certain default values. I haven't seen on any ACER site, that there is a new firmware or gonna be and neither how it should be "installed" on the TV. So, I would be pleased to hear, if there are some news.

    I have a westinghouse flatscreen tv that changes channels on its own. It moves down one channel at a time slowly over and over. Any suggestions?

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!

    My Acer TV AT3201W seems to have the same main controller board as the AL2671W and has a serious design bug. The serial I2C EEPROM chip 24C32 contains all the settings. It has a write protect pin and has guaranteed 1 million write cycles. However the firmware of the TV writes about every second into the chip. This can be observed by connecting an oscilloscope to the WP (Write Protect) and the I2C signal pins. After 1 million second watching TV the 24C32 chip runs out of its guaranteed specification and might therefore be broken. 1 million seconds are just 277 hours watching TV! The firmware update might hopefully remove this bad firmware design bug, but obviously it can not repair a broken chip.

    I have an update: I have achieved better color balance by using these values:
    R gain: 630
    G gain: 630
    B gain: 630
    R bias: 242
    G bias: 217
    B bias: 242
    Saturation: 40

    In this way the picture has better appearance.

Call Acer.
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

What you need to do is retune the TV, but when it is finished look at the regional settings. Or if the regional option is available before retuning, retune selecting your area so then you get normal BBC channels. It's likely that at the moment the channels for BBC are located at the very top end of the channel list say? - channel 800+.

You are clearly picking up signals from many transmitters. With regional settings you can change it to the area you live in.
But you will have to take into account how good your aerial is. Otherwise the signal quality will not be good on same transmitters. So the set may only suggest those with the best quality signals.
ITV stations might also change.
When done it will move the channels you mention to the top end of the guide, to 800+.

Note many HD channels have no regional options. For example here in Yorkshire we only get ITV Granada and not Yorkshire TV on the HD channel for ITV1. And BBC1HD does not show any programmes when local news comes on.

There is not a problem with the TV despite it's age this is can be due to your reception of the digital package for BBC. Have you checked through he full listings? sometimes the BBC channel will be at a different number setting because of the transmitter you are receiving. I assume you are using a digital box, you can enter a menu which will give you an indication of the strength & quality of the incoming signal. Do you pick up some of the other BBC channels such as BBC3 or CBBC? It's possible your aerial strength is a bit weak for the digital BBC package & you may need to have that looked at.

Hello, I seem to lose the (digital) ITV channels in poor weather.

I would get the aerial checked there may be a problem
