Re: pn64e550d1fxzc power issue

Each capacitor has one leg soldered on the top of the board as well as all on the bottom.

Flood the pad with fresh solder and use desolder braid to remove the fresh solder. Fresh solder tends to be easier to remove.

Re: pn64e550d1fxzc power issue

On that model, you disconnect the cable from the power supply and put a wire in the ps on and the other end to the ground. Then on the mainboard, put a wire in holes 3 and 4. Then plug in the tv.

Re: pn64e550d1fxzc power issue

These are the holes. I hope you didnt do any damage to that chip.
The top 2 holes should be #3&4.

Re: pn64e550d1fxzc power issue

thanks tried it and still nothing. so that means i have a power supply issue? thanks doesnt try to power on no noise or anything

Re: pn64e550d1fxzc power issue

That's how I had it.

[tvtimmy]

Re: pn64e550d1fxzc power issue

The number of the holes is:
3 4
1 2
Put the jumper in the two top holes.
