Hello!

Good day! Please somebody help me to identify the location of the protect pin or a pinout of this driver board. I know this is generic driver board. Kindly lo see the attachment. Thank u.

I don't have anything on this board but if no one esle can help, I'll try to help if you can tell me more about what you're trying to do.

This amp goes to protect mode...i dont know what is the source of the protection but previously it was Intermiitent. Kindly give your usual help....

Pin 1 of the tl494 is higher than pin 2(6v, 2.5v respectively) i dont know who is givIng that high voltage. Thank you

Solder a bridge between pins 2 and 3 of each of the audio driver ICs (the ones with the heatsinks). Does the amp still go into protection?

Yes it still goes to protect...

Is there any DC voltage present on the output filter inductors at any time?

No voltage presents at any time.

Hi perry, here are the photo. Thank you Perry

For the LM293 on the back of the PS board, which pin is high, pin 1 or pin 7?

If you cannot get to pin 7, I think the anode of D37 is connected to it.

Pin 1 and pin 3, i short the pin 3 to pin 4, protect disappear and powerup,but the amp is muted even before we put standby he audio driver.

 

[Perry Babin]

That doesn't answer my question.

 

[nonprof]

That doesn't answer my question.

Sorry. pin 1 is higher. 6.8 vs 0.115

 

[Perry Babin]

What's the DC voltage on pins 2 and 3?

 

[nonprof]

What's the DC voltage on pins 2 and 3?

2.5v and 4.7v

 

[Perry Babin]

Confirm that pin 4 of the driver board is remote and pin 6 is B+. If so, what's the DC voltage on pin 11?

 

[nonprof]

Pin 5 is remote and pin 10 is b+, pin 11 measures 12.3v

 

[Perry Babin]

Which pins of the driver board connect to pins 9 and 10 of the driver IC?

 

[nonprof]

Sorry Perry,previous post is wrOng, Ive started in a wrOng direction. Now From leftmost facing the component of the power board the sequence are Pin 4 is remote, pin 5 is b+, pin 6 is Gnd and pin 11 measures 3.2v.

 

[Perry Babin]

Pins 5 and 6 are reversed from the information I have. I'll try to find something that matches what you have.
