dmtech tv retune???

Your Help was of Great Value to me in being able to get back into Digital TV on my DMTECH Combi TV which I had been Locked Out from so unexpectedly.
Having E-mailed DMTECH as to this unexpected problem that arose. To which I have received no response as yet from them !!! C'est la vie
There was nothing in the Owners Manual Instructions relative to the message coming on Digital TV Screen
" Enter Lock Key" neither had I entered a Lock Key No, ever. I had re-tuned it so many times on Analogue to no avail. Thanks Again for your HELP xx

Please fallow bellows instruction to retune your TV.
Could you please follow that EEPROM RESET INSTRUCTION OR FIRST TME INSTALLATION.
Also please don’t forget that MENU BUTTON from your remote, it’s not the one in the middle of remote.
There are the other MENU BUTTON in left down bottom side.
Cannot access Digital TV and am asked for a Lock code Key?
If you cannot access the Digital TV option then conduct an EEPROM RESET as mentioned above. If you are prompted to enter a lock code key enter three / four zeros.
Alternatively when prompted to enter the lock code key conduct a FIRST TIME INSTALLATION also mentioned above.
There are two options available. The first option is to conduct a general reset that will reset all user preferences. The second option would be to conduct an EEPROM RESET. An EEPROM RESET would reset all the internal hardware.

Instructions - Please refer to your DMTECH remote control and user manual provided
1. Turn the Television ON ? Button on front of Television / Power button on remote control.
2. Make sure that you are on Analogue television by pressing the TV/DVB-T button until you see PR and the channel number selected in the top right corner of the screen, e.g. PR 1.
3. You must then Press the button labelled Display until a window titled INFORMATION is displayed on the screen.
4. Only when the window titled Information is present can you continue by pressing the digit (1) twice and then pressing the button titled LINE. If you make a mistake then press Display again to remove the window titled INFORMATION and repeat the process. (Display - 1 1 - Line)
5. Once you have successfully completed step four you will notice that a menu appears on the left of the screen. You can then select which option you want, either RESET or an EEPROM RESET using the arrow keys. To execute an instruction please use the RIGHT ARROW KEY and not the ENTER button.
Make sure you have properly conducted a FIRST TIME INSTALLATION and an AUTOMATIC SEARCH. If having done this you can try conducting a manual search in an attempt to force / lock the channel.
This will erase the DVBT tuner memory and reset the interface card. This may resolve poor channel reception, the inability to store channels or even receive certain channels.

Instructions - Please refer to your DMTECH remote control and user manual provided
1. Turn the Television ON and select digital television by pressing the button labelled TV / DVB-T located under the power button on the remote control.
2. On the remote control locate and press the button labelled Menu, found at the extreme bottom left of the remote control.
3. A Menu should now appear displaying options. Scroll down and select the option labelled SETTINGS using the ARROW KEYS and the enter key located in the middle of the remote control. On the next menu you must select INSTALLATION to move on to the next menu.
4. On this last menu scroll down to the last option labelled FIRST TIME INSTALLATION and select it pressing the enter key. You will then be prompted to delete all channels, using the left arrow key to select yes and press enter to execute. The television will reset and prompt you to commence an AUTO SEARCH. Follow these instructions to tune in channels.picture
Digital Television requires much more from existing aerial systems. Having more than one digital TV may reduce signal quality and strength depending on how the aerial system is set up. It is therefore recommended that if you decide to use more than one digital television you use a booster and or at least make sure you are using a digital ready aerial. Using an existing Aerial that is split may reduce signal strength depending on how many times it is split. Please see the diagram below. The best solution when using an existing aerial is to purchase a booster device. Aerial Splitting - Why a booster is recommended. A booster is used to apply a small current that boosts the existing signal. A booster can be purchased from all main TV/HI-FI - consumer electronic product retailers.

Hi,
I had the same problem. Go to this page on the DMTECH website and follow the instructions and it will force 'First time installation program search' just like when you brought the TV from new.
