Appliance Repair Questions? Ask a Technician for Answers ASAP
Firstly we need to diagnose the fault before taking it back to Currys.
I would start by removing any unnecessary cables (HDMI etc), so you are left with just the power supply and coax cable.
Turn the TV on, and check your getting sound.
Using the source button on the remote see if you get anything showing in the top corners of the TV to indicate what source you are connected to, and check when pressing the remote the standby light flashes.
Secondly press the menu button and see if anything is displayed.
Please let me know the outcome of these troubleshooting steps.
I just wanted to follow up and check if you required any further assistance?
