I bought HT-R508. I spent nearly two days to try to get the sound through speakers. I still couldn’t get a sound from my ps3.
Actually I tried nearly every solution that I could do and tried troubleshooting through the manual. But I think I am missing the point at DTS settings. I am able to see the picture from ps3 1080p with no trouble. I can hear the sound from my tv through amplifier aswell. But no sound from my speakers. Also my speakers are all correctly connected because I am able to listen to my I pod through the onkyo amplifier..
My connections are:
hdmi cable from tv to onkyo hdmi out.
hdmi cable from ps3 out to onkyo hdmi in 1
digital optical cable from ps3 to onkyo digital optical in1 (i did this just incase also tried it with out aswell)
The dvd which plays in ps3 is DTS feature. I also did the sounds setting from the dvd menu to DTS 5.1 and also tried 5.1 doulby digital aswell.
I also did my auto microphone settings and didn’t have any problem.

Have you assigned the optical input to the input you are attempting to use? Scroll through all inputs and you may find the sound is there. If not check the optical cable is working (red visible light) Also a big one is making sure in your ps3 settings that the setting for audio out is set to 'optical'
You may have a bad speaker that does not have enough electrical resistance - low resistance looks like a short circuit to the amp.
You could also have a single fiber of one speaker wire touching the other speaker wire before they get to the speaker (that is, the two wires at one speaker are touching each other near the terminal posts on the amp or near the terminal posts at the speaker). Check all speakers.
Try switching power amp output's to the speaker's and see if it still does it if it still does it the it's the speaker ,disconnect every thing from the input's of the power amp if it stop's start pluging thing's in one at a time ,process of elimination best of luck
In old stereos the first things I look at are output transistors, solder joints and electrolytic capacitors. If you know how to solder, bad solder joints are pretty obvious. If you need a tutorial on how to spot bad solder joints, look here.
As for bad caps, look here. The info is aimed at computer motherboards but still helpful.
Have you checked your HT fuse. If it fails it will have lights but no sound. Pays to check fuses with a multimeter, as they sometimes look good, but can be dud.
A faulty or intermittent lead speaker box lead will aldo make the head blow fusesCheck the lead to your speaker box also. Dont use a stomp box patch lead. be sure to use a decent speaker lead with quality jacks(switch craft) and at least 16 gauge cable. Ernie Ball make a decent speaker lead for guitar rigs.
If the head keeps blowing fuses, I would suggest that you change you output tubes(4 x 6L6GC). I recommend Electro Harmonix, by Sovtek as a budget conscious option. Get them as a gain matched quartet.
If it does not have a blown fuse at all... then get back to me here and we can do some more tests.
I am more than happy to answer

either your DSP output stage already damaged or maybe your speakers. have it both chekced for short. or worst both of them. DSP A1000 can drive as low a 4ohms on main channels but how is the power handling of your speakers? are you sure it has not exceeded the capacity of the speakers? or maybe you have over driven the speakers and they are still ok but your amp gut busted due to over drive. If the DSP amp is busted then it is due for replacement of power transistors and drivers. you can not disable the protection circuit. at least the design. it can be disabled by a tech person with a lot of modifications but i wont go for that or it can cause more damage to your equipments. i am from yamaha before and i have made conversions of protection circuits but it is too risky.
