Hi all, I recently purchased an onkyo TX SR-606 AV Receiver used but in seemingly perfect condition all round. (even had the box!) Everything had been working perfectly and I was very pleased with onkyo's performance. Unfortunately it generates alot of heat so i decided i'd grab a new TV stand to give it some proper ventilation. Everything was transferred okay and working perfectly till I came back home after nipping to work, turned everything on and stuck in a calibration DVD so that I could calibrate my rather bargain basement plasma. During calibration the display started to flash every sort of 10 seconds or so, each time showing a short of white fuzz over the top of the output from my PS3. (abit like if you're trying to watch freeview with a dodgy aerial) This also happens on the PS3's XMB. However weirdly this doesn't appear if I open the receivers setup OSD or im watching Freeview with the TV's built in tuner. Can anybody help me? Thanks in advance! EDIT: My setup consists of: Samsung PS51E450 51" Plasma. Onkyo TX SR-606 AV Receiver Mordaunt Short 914i's with ms90* series centre and surrounds. Mordaunt Short MS308W subwoofer Cheap HDMI cables (>£5.00) The only thing I changed between the old stand and the new one was the speaker cable for the front speakers which is now Cambridge audio Symphony 200. But as mentioned before everything was working fine on the new stand just before I went out!
