20 Most Recent Onkyo TXSR508 Receiver Questions & Answers

both circuits rely on a good signal. Check your connectivity, especially if your using HDMI cable. Swap it out for one you know for sure works, you might get lucky. The HDMI board on these get very hot and should be suspect. Hope this helps.

You could check your voltages before and after you loose audio and see where the voltage changes. Working backwards from output to input. I use a signal tracer or a small wattage speaker such as a ear bud. If you don't have access to a oscilloscope. when using an ear bud I would start at the driver(low wattage) the pa would blow it.

The only way you can do this is by connecting the Cable Set Top box HDMI directly to the TV HDMI input and switching the TXSR508 to Apple TV. And if you want to hear the Cable sound through the TXSR, connect analogue audio out of the TV to one of the analogue inputs of the TXSR ( Aux or Video In ). You may not get the Cable TV's Dolby 5.1 sound but you will get stereo sound which on using the TXSR's dsp setting ( ProLogic II ) can be made into 5.1.

The reason you are not getting a good picture is because of the HDMI interlink cable. Make sure that the HDMI cables you have bought are at least version 1.3a. May be one of the cables is v1.3a that is why you are getting OK picture when you connect the projector directly ( it might be an expensive cable ) . If you do not get v1.3 you may also buy v1.4 which is 3D ready.
The poor band width of the cable must be giving you a bad picture.
Now if both your cables are OK and you are still getting a bad picture you have faulty HDMI pass through circuit on your TX-SR508.

Onkyo has a mod. for some units hdmi problems. I believe yours is one of them. It needs 4 capicators to be installed. I don't know if All Brite is an authorized servicer or not. If they are they shoud be able to access the info for the repair.
