Re: TNPA5623 schematic Panasonic needed

I may cave and get the cheapy hot air rework station to pull the chip and not do any more damage...don't see how else to get to the solder under the IC.

Martino,
Just looked at your post again...do the red x's on your board mean no connection?

Re: TNPA5623 schematic Panasonic needed

Thanks....weird because I checked the component alone and dont see that short (crappy multimeter leads perhaps).

Does the solder flood and wicking method work well to remove the IC? I dont have a hot air tool unfortunately

Re: TNPA5623 schematic Panasonic needed

Just removed D041 from the board; the component is not shorted, but the throughholes on the board for legs 1 and 3 are shorted.

Is that normal??

Re: TNPA5623 schematic Panasonic needed

Just found this thread, trying to repair a TNPA5623 with my amateur grade tools.

I bought the ShopJimmy kit and replaced R051 and D041 and Q051. The old Q051 was shorted, but D041 was not. Now that I have the new D041 in the board, legs 1 and 3 are shorted.

Is it possible that my soldering iron somehow damaged D041, or the pads below it? I am leery to connect up the board and blow something up, doesnt seem like these 2 legs should be shorted (and the new component was not shorted).

I did not replace...
