I have a TV with a HDMI port which I believe to be having signal problems. I have tried multiple HDMI cords and devices and the problem happens with each one. I was wondering if anyone knew of any easy temporary ways to resolve this problem in the short term until I can get a new TV? Usually when this happens frequently in one session I would disconnect the HDMI cord to force a new handshake between the devices, This works but I was wondering if there is anything else I could do to help "patch" this issue? Thanks in advance.
