When I plug the LCD TV/DVD Combo in I get power with the backlight lit and display such as HDMI or DTV or DVD in the top right hand corner and it will respond when using the 'source' button but after about 5 seconds EVERYTHING disappears and the set will not respond to the remote control but the backlight stays lit. I have taken the back casing off of the set and examined all the circuit boards for obvious signs of blown Capacitors but cannot see any with the naked eye. There is a slight 'ticking or clicking' sound coming from the circuit board area that holds the aerial and HDMI inputs etc. ? ANY IDEAS PEOPLE PLEASE??? Thankyou in advance!
