TV forgets channels when unplugged

My Dell W1900 LCD TV is a couple of years old. Whenever we unplug it from the wall (or have a power cut), it forgets all its channel settings. I'm guessing that there's a backup battery in there somewhere that needs replacing - does anyone know whereabouts inside the set I should look for it?

Re: TV forgets channels when unplugged

Has it always forgotten the channels when you unplug it or is this just a recent development? I know that on my old standard tube television or VCRs, the channel memory is always reset if they are unplugged - the same being true if the power goes out.

For the past couple days, my 32" samsung LCD will cut off by itself. It won't come back on unless I unplug it. A little while later the same thing occurs again. The TV is not even a year old yet. What...

Since it is still under Samsungs' 1 year warranty period, you can call 1-800-samsung and they will set up the repair with the closest authorized service center at no cost to you.

When i cut my tv on it cuts off i have an hitachi 42 inch

TVs don't like being cut. It breaks them.
If you meant to say "when I turn on my TV, it turns on for a second then turns off", call Hitachi.

Help me turn my tv on

Dell are a bunch of rip off artists.

Dell tv/monitors turn off if there is no input coming from the selected input. In this case DVI, try powering on the TV and using the menu buttons along with the channel Up/down buttons on the tv to select a different input.

Hopefully this works for you.

My main menu button is locked and don't know how?! Any ideas? Its a dell multimedia 19" flat LCD.

if its a w1900 this is a known setting. Press the menu button on the right hand side of the TV (second button UP, just above power/standby. Now, WHILE THE MENU LOCK MESSAGE IS BEING DISPLAYED, press CH ^ and VOL - AT THE SAME TIME. Menu unlocked message should be displayed.

And you're done.

Might take a couple of tries - this tv/monitor is a bit fiddly...

I have the same problem also. I am assuming that the power supply is bad. I have looked everywhere and can not find a replacement or the pinout on the supply. If anyone can find a service manual or a replacement board, please let us know.
