I've been having trouble with my Yamaha RX-V371 surround amp with a slow signal detection issue. I'm running everything through the amp (with good HDMI cables) which is the cable TV box (Foxtel IQ2 in Australia), LD Blu-Ray, LG 3D LED TV, and XBOX 360. We mostly just use the Foxtel box and the issue is when I turn the three main things we use on (i.e. Foxtel box, amp and TV), after it being off for an hour or more the amp seems to have trouble detecting the signal with the picture coming on and off for a second or two (sometimes a green or white noise screen appears as well) followed after a minute or so with a stable picture but no sound. The sound eventually is detected and comes on after a couple of minutes and all is okay. When we turn everything thing off and leave it for an hour or so, the whole screen flickering, no sound, etc issue starts all over again. Very frustrating.
We've had this set up for about three years now and it used to work fine. Everything when turned on came on straight away. The issue seems to have started over the last six months or so. I've tried reading up on it but can't find an answer. As I've mentioned, when everything is 'warmed up' it works fine. We get a good picture in HD and sound in 5.1. I've tried turning ARC off and on the amp (The TV does not have ARC), resetting the amp to factory settings along with the LG TV but the issue persists. At first we thought it was the Foxtel box so we got it replaced but no change. I also then tried testing each unit by hooking up each one direct to the TV with no problems (picture and sound straight away) so the problem seems to be the amp itself. Is the HDMI decoder in it playing up?
The amp is now out of warranty so before taking it to a Yamaha service centre are there any other suggestions to fix this issue?
