Right this is going to take some explaining, so if you think you can help then make a brew and get comfortable.
I've got a self built HTPC, Xbox 360 and Sky+HD box all connected to an Onkyo HT-R390 via HDMI leads which is then connected to my TV via a HDMI lead. It's all been working just fine on my 32" which I've had for years so decided yesterday I would buy a 42" to replace it. Link to new TV.
All I did was swap the TV's, I did nothing else. Didnt change any leads, or alter any settings. I watched Sky for a bit yesterday afternoon and everything seemed great, really happy with my new TV. Then in the evening I started up the HTPC so I could watch a movie, straight away I noticed it was suddenly 'snowing' inside my TV.
I checked all the connections, I checked the settings on my new TV, I double checked the connections, I then reset everything to factory settings on my new TV and the Onkyo, I even swapped the HDMI inputs around. Everything had 'snow' on it. By 'snow' I mean loads of little white dots flashing on and off all over the screen.
Here's where I try different solutions so bare with me.
Not fixes
- I disconnected everything and reconnected it all. Same problem.
- I disconnected everything and reconnected only the HTPC. Same problem.
- I connected the HDMI output from the Onkyo to HDMI input 2 on my new TV. Same problem.
Fixes
- I connected the HDMI output from the Onkyo to my old TV. Problem gone.
- I connected a HDMI from the HTPC straight to the new TV bypassing the Onkyo. Problem gone.
So in conclusion, bypassing the Onkyo works on my new TV but connecting the Onkyo to my old TV works. Both TV's are LG. The Onkyo pulls the 5.1 from the HDMI and my new TV only has 2 HDMI's so I cannot remove the Onkyo from my setup.
Can anyone shed some light on why my new TV doesnt like the signal from the Onkyo? I just cannot work it out.
