My acer lcd will not keep the channels ihave to tune it in every time

Go in to the TVs menus, choose the TV Tuning options. Follow the menu path until you find the option for Auto Tuning.

That's about it. Not difficult.

try calling cable operator

ihave the same problem with my lg

Most sets with digital tuners do this. The best thing to do is manually save them into memory, unless they are the same numbers, this would keep the channels tuned until you go back to them

Any vcr I know of usually is tuned through channels 3 or 4 unless they are hooked up directly by RCA patchcord. 3 pronged- 2 audio and 1 video. With the patchcord you'll be tuning through an auxilary input in the tv.

It is the software or the program that have the TV to operate properly.  Sorry for my english.

* Connect Yellow wire to continues power ( it is back-up power to memory circuit)
* Connect Red wire to switched power
You can download User Manual and Installation Guide for CDX-S2000 from Sony Support for more information.

The retuning process is as follows:

1. Press the [i+] button on the remote control to display the DIGITAL INFO menu.
2. Press the BLUE button to display the MAIN MENU.
3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
4. Press the RED button to start the auto tuning process for all available digital channels.
5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

1. Just tune to the 2nd channel you like and press red (record) button. You'll see rec sign on top left.
Do not move to other channel.

2. Press List and scroll up and down to select the record in the list and press OK.

Sounds like the signal is probably too strong. The TV is not the problem.
