Samsung PS50A476 - messed up - lifted pads

[dizzycap]

Hey guys, I messed up, tried to desolder a cap and lifted the pads, my tip wasn't in great nick tho ive replaced it now :-(

Is this fixable by bridging wires to the tracks?
I have a rough idea where the wires would go, not 100% tho as its thru hole,

thx



Samsung PS50A476 plasma, powering on ok, no display (very very faint bars) sound ok. 3 bulging caps on sustain board

Your lucky , its not that bad! Remove the solder and clean the pads with some alcohol.

There are 2 options :

1st option , You solder the new capacitor on the 2 pads. ( Like SMD capacitor ) 1 pad the solder is intact , other pad the copper is still visible.

2nd option , 1st picture: Remove all the copper and clean the pads. Left pad is still intact , other pad you need to use the TP1047. ( Test point ). You might need to scratch so you can see the copper again.

Also , the print has many layers so you will be fine. You need to remove all the existing tin , clean the pads and install the new capacitor. Add some solder on the topside and bottom side and you can't go wrong.

thanks for help Moreno83

I went for option 2 and soldered the + leg thru and bridged it to TP1047.
I tested for contunuity from TP1047 to D5702 all good
