TDA7350 in bridge mode - sending constant 4V though output!?!

[minifly]

I'm fairly new to the whole amplifier game, so I decided to use chips that gave good sound in an old Altec Lansing Hi-Fi system I had, the TDA7350. I've followed the bridge test application circuit on the datasheet, but I'm getting a constant 4V across the outputs on top of the amplified output. If I put a 1000uF electrolytic in series with the speaker/load I get fairly good output, but with more static than I'd like. From the datasheet, and what I've read, in bridge mode the circuit shouldn't require a capacitor anyways.

Have you got any ideas for what might be wrong? I've gone over my veroboard for logic errors and dry joints about 10 times now...

Thanks.

If the voltage between pin-8 and pin-10 is near zero,then it's ok.

Hmm,

I'm not sure what to tell ya,The bridge application worked out great for me.

Here's the schematic of my version;

An externally hosted image should be here but it was not working when we last tested it.
