How was set the LED drive pins?
Drive mode is important
strong drive or open drain, drive low is better.
Look at blinking LED example of Pioneer Kit.
That has same circuitry same as yours.
Have a cathode drive LED.
If not have the kit, down load the documents and take a look.
Ah, I forgot the picture
Yes I'm using strong drive. And I tested example with PSOC Creater and got same result. =(
Oh, my browser, safari become get wrong to uploading.
IE9 also, what is going on?
Upload your project bundle, I will be check it.
Minimaled design is better, LED part only but has a trouble.
Can it be that you mistook pin 2 (Vcc) and pin3 (blue)?
Some thoughts, questions -
1) Your Vcc is "stiff", no voltage droop when LEDs come on, restarting processor ?
2) When you see LED pin not going to ground, what voltage do you see when it
is logic low ? Keep in mind it will not go compeletely to ground because of Vol spec,
and is not a super low RDSon output . With 1K, LED drop of 2V, you would expect
Vol (LED on) to be ~ .2 V.
3) You have confirmed 1K LED R's are 1K ?
As I look your circuit, "open drain, drive low" drive mode is also usefull,
for your cathode drive LED, it's not depend Vdd of PSoC.
Would you try it.
Mostly wanted information is wave form of LED pin.
Would you show it.
Oh, so many post, thank you all for your comments.
Project in attached file. I tryed "open drain, drive low" and also negative result.
To Bob Marlowe
No, I don't mistook pins. I reviewed it some times.
1. All okey with input voltage. It haven't droop.
2. I see 0.9 V and about 3 V on the LED pin (instead of about 0V and 3.3.V)
3. It's most interesting question, and answer bellow:
I read in datasheet that max current on the pin is 25mA. Before 1kOhm I used 360 Ohm. 3.3V/360Ohm=9mA. But if look to Dannas image: I had Current :"4mA source, 8mA Sink". May be it killed ports?
I tryed set Current as on Dannas image: "8mA source, 25mA Sink" , but got error : "Pin 3 does not support SIO":

TRY EXCEPT CHROME, BUT IE, SAFARI, FIREFOX is OK
