There is not enough information to give you an answer. How do you know you are getting digital and not analog. Most LCDs are only digital even on their TV antenna connection using the ATSC tuner, so I don't really have enough information. If you are referring to the TV antenna, I assume that you have an antenna designed for this purpose.

It may have gone into safety shutdown because it sensed short circuits in the power supply or in the backlight inverter board, you will have to look inside. Please read my guide to understand what the TV needs to operate.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Increase your signal frequency to 60hz. You may have to lower your resolution also.

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


If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

Unplug the TV from the mains for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. As there is no sound just make sure to check all the connections at the back, if still the issue is there then for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment as these sets have high voltages running even when switched off.

Please do accept the solution if the issue is resolved or else revert for further assistance.

As Bob Myers mentions, the question can't be answered unless you explain which video output the camera has. The solution for a BNC CCTV camera would not be the same for a PoE IP camera. Provide that information, and we can suggest hardware that would connect your TV sets and project to the camera feed.

All Acer TV models use the universal Remote Control code NEC 18E7, which most of universal Remote Controls can use. We recommend using the search function, available on most universal remote controls, to find the compatible code for your Acer TV.
