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

Re: TV losing its channel memory

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!

Re: TV losing its channel memory

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

On my Techwood it as built in freeview but every other channel is right except bbc1 and bbc2 both channels say bbc wales,How do i get them back to bbc1 and bbc2 please PLEASE HELP.THANK YOU.

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.

Sounds like you need to check if the tv is set to the right BBC is region orientated.

Digibox troubleshooting

You need to do a Full Factory Reset tuning rather than just a rescan.

Rescan simply looks at the place holders where the old channels were stored and refreshes them. A Factory Reset (A.K.A. Shipping Condition) wipes the channel memories and starts again fresh.

If that doesn't solve it then it could be a problem of too much signal on certain strong channel groups (BBC and ITV). Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range. If ITV has been moved to where the aerial is stronger then it could be oversaturating the tuner.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

Why do I lose All BBC channels every time it rains It is an LG tv with built in freeview

Are you using a Satellite dish for your signal? Rain adversly affects signal with satellite dishes, or if the incoming signal is from a satellite based transmission from the BBC, channels will be "knocked out" temporarily.

How works time shift

Time shift is a very handy thing... it works by buffering the channel you are watching, that is: it continuously records the channel as you are watching it. The time it records for varies from make to make... Humax machines record a 2 hour "buffer".

Example: If you leave your TV on say ITV and go out, you get delayed when you are out and miss your favorite show, when you come back you can effectively rewind live TV and watch your show. However this only works for the channel that the TV is left on.. if your TV is on itv and you miss a show thats on the BBC then you are out of luck. as you can only rewind what the tv has recorded (the channel you were watching last)

I hope this is the info you were after... if you want / need more info leave a comment and i'll try to help you.
