Hey y'all,

I know it's an old unit. But before I go tossing money on additional speakers or swapping it with my unit. I'd like to know if this unit is malfunctioning or my parents really needs additional speakers.

Now, before I hear it. I am FULLY aware of the capabilities of this unit with only two speakers.

Every time I go through the setup process in full auto with the mic. It will go through the "speaker yes/no" section. Hears the front 2 speakers. Notices there are no Center, Rear, Rear Surround. But once it completes the Rear Height, the unit shuts off and the Wireless indicator flashes.

After I turn the unit back on, I cannot enter setup again for at least one minute. Either nothing happens or the screen says "Please Wait..." blacks out then back to the source that it's currently in.

If any of you still have this unit. Can you please run a set up with only the front speakers connected? I really like to leave it with my parents without having to swap mine with theirs with a 3 hour drive one way. Only to find out they need more speakers. Or spend the money on more speakers only to find out that the unit is defective.

Much appreciated,

KOT

Why do you want to use the Mic for setting up stereo?

There seems to be a noticeable delay on the audio to the video. Figured the set up could help. Idk

Which source(s) have delay? All of the sources are connected via HDMI?

Any lip synch settings that might have been overlooked?

I have no experience with this unit. Is there a “direct” setting?

I’ve encountered some ugly video delays in TV’s and cable boxes. In one case I found that the cable box allowed sync adjustment. I had to add 150ms in the cable box and 80ms in the audio system. Sync was still not great.

Yes, all sources are via HDMI. I don't know of any a/v syncing settings. Unless DishTV has one that I don't see.

However, I think I might have found the issue. The far right, when looking at the rear of the unit, speaker terminals are bent. These are the Surround Back speakers. I was able to find some car speakers with no box and hook them up. When I plugged them into the Surround Back. The right channel only produced the "all speaker" sound. But as the system goes around to check each speaker, it shuts down when it gets to the Surround Back left channel. Right channel is perfectly fine.

Looks like I'll have to take this thing apart to see if the speaker terminal is shorting out to chassis.

I would make sure the Left - Left + aren't shorted- the speaker - are common, so they can touch without problems.

Are you SURE about that!
That Pioneer uses Digital amplification (Class-D). Most digital amps use BTL outputs. Meaning the negative terminals are NOT ground! And are not connected to one another. So shorting them together or ground will send the amp into protection. Or worse if the protection circuit doesn't respond well enough, burn the amp up.

This also becomes important when using cheap volume controls on digital amps. Some cheap volume controls have the negatives tied together, sending the amp into protection when used.
One brand name that still does this is Russound. Their volume controls are the same ones they have produced since the early 90's and are common ground. Even thou they have digital amps with non-common ground in their lineup. Just stupid.
The one time I saw this burn up an amp, was with a NetStreams keypad (which used a digital amp). Installing company used a cheap volume control for a bathroom, split with the bedroom. Keypad kept shutting off and eventually burned up. Original company could never figure it out and eventually stop responding to the customer. I was called and fixed it pretty quickly.

[Note]:
I don't know if that Pioneer uses common ground or not. But being it uses Class-D amplification, it's a good bet that the grounds are lifted. A quick check with the multimeter would easily verify.

Thanks- I didn't know it was ClassD and I stopped doing anything with Pioneer after they removed themselves from the market- won't use anyone who does that because I don't want to leave my customers hanging.

I should have posted something about checking it, but assumed that would be the first step before doing anything.

I'm not sure that the problem is really something touching on the speaker terminal thou. You would think the amp would simply go into protect mode if this were the case.

I think it more likely the processor is experiencing an issue.
I would try defaulting the processor with a factory re-initialize first. (something that should always be done with a new installation anyway).
[with the unit off - hold enter & power on the front of the unit for a few seconds until menu pops up - use arrow keys to select 'reset' - press OK, then OK again to confirm].

I removed the top cover then spent 20 minutes removing the rear. Only to discover I would have to remove the low voltage stuff to get to the amp section. I don’t have a desk, or a magnifying glass or the patience right now.

So I took it to a local electronic repair shop on Sunday. They should get back to me in a day or 2 with an estimate of price and time frame.

I did a quick test with a meter. Albeit the probes suck and I know I need new ones. But the left rear did show 100ohms neg to pos. Whereas all others showed 1.2Mohms.

And it does go into protect mode as soon as the test audio reaches that channel. Whether a speaker is plugged in or not.

I wonder if I could force it to have those channels go to the pre-amp outputs.
