Re: My awa digital tv has suddenly lost all tv channels...
It sounds like you have lost tuning,you will need either the tuner or Main PCB. It's possible you don't have tuning voltages from the power supply, but most likely your problem is with the MAIN PCB.

Are you trying to get over the air channels? IF you are does your TV have the digital tuner on analog? TV went digital and if you have an analog tuner will need either e new TV or converter box.
hi your signal could be to strong, on the aerial cable the thin brad rap 4 strands around the center solid pin then retune in auto, if this does not work you may to manual tune it in, or get someone to check your aerial and you could try a firmware update on your tv hope it helps
Channel memory of stored channels is contained in a Eprom which may be part of the microprocessor------voltage when set is shut off is often from either the standby supply or even a filter cap that holds sufficient charge to maintain voltage for the memory.
Look in those areas first.
An alternate way would be to go to a box and input signal to rear audio and video jacks---the box would then retain channel memory etc and this would bypass your issue.
Sounds like an Aerial fault. Obviously, the first thing you should do is check the the aerial connection to the TV.
Simple test for the aerial is to connect another television to the aerial connection for the faulty TV. If the second TV is OK, it's a faulty TV. If neither work, it's an aerial or aerial cable fault. If you don't have a spare to test with, can someone loan you one for a short time?
If neither work, check the aerial itself? Has it moved in the wind? Is it still pointing the right way (towards your transmitter). Has an element (one of the metal fins) broken off?
If it's like the DR620 it will only receive analogue from the TV aerial. I connect the AV out connections on my set box to the inlet AV on the recorder and watch and record through the recorder's "rear AV input" selection.
