Default Another ir2184 base amp

The amp is going in protect.I could not find any fault so i disable the two driver ICs.By mistake instead of bridging pins 2 and 3 I bridge pins 1 and 2.Now amp is out of protect.
What does that indicate?
What should i check when it is in that state?

I can't say what that means since I've never tried it.

Remove bridges and make sure that amp acts as it did before. Then short 2-3 and check the signal up to the IC if the amp no longer goes into protect with the 2-3 short.

Did you jump 2-3 for both ICs?

Do you have signal coming into the driver board?

Solder a 10k resistor bgetween pins 1 and 2 of U3. When you drive a signal into the amp, you should have signal on pin 1.

On U4, you should see a square wave on pin 7.

You should also have a 10v square wave riding on the negative rail on pin 1 of the driver ICs.

That's a driver output.

Check signal on pin 1 of the TL072 and pin 7 of the LM211.
