PC HDMI to TV HDMI no signal
Posted on 2013-01-18
We have an LG TV (42LT360C) that is connected to a computer via HDMI. The TV has 3 HDMI ports - HDMI 1 and 2 to the rear of the TV, HDMI 3 to the side. The computer was originally connected to HDMI 3, but after turning the TV on from overnight standby, it indicated 'No signal'
We have since tested connectivity (to HDMI 3) with other TV's (different makes and models) using various computers and experienced the same issue.
It should be noted that the HDMI 3 ports tested were all to the side and do not appear to be integrated to the same board as the rear ports.
HDMI 1 and 2 have been tested over a period of 4 days and dsplayed correctly after being in standby over night. However, the equipment has since been delivered to our customer and the 'no signal' previously experienced with HDMI port 3 no occurs with HDMI 1.
The 1.8M HDMI cable is gold plated and of reasonable quality. This cable runs in a short conduit alongside the TV power supply.
The installation is fairly basic and I am struggling to get to the bottom of it. Could anyone shed some light on this issue.
