Whites Surf PI schematic

[Falcon]

Hi, liekwang, I'll try.
also changed the CI "CA555" (TLC555 in the original) by "NE555P" (only one found), but nothing changed, still does not work, just one "Beep" continuous.
I do not know what to do, do you have any idea?
Thanks.

Falcon,

I had similar problem with surf pi pro and I changed from BC transistor to original 2N3906 ...
something was not working with that BC replacement

[liekwang]

?Falcon and ndesis try to play all the potentiometer towards the left all is still sound a continuous beep and see if the solder less stick sorry my English is bad

[Falcon]

Hi, sdesic, which transistor BC you used?

liekwang, no matter how the potentiometers turning the "Beep" is the same, you say to solder the circuit again?

[sdesic]

Falcon,

it was BC557C and did not work for me.
I know it needs to be reversed because it is different pinout from 2N3906 but it still does not work.

I replaced with 2N3906 and it worked OK

[Falcon]

I already use the 2N3906 (Q1).
which 555 (U1) do you use?
I use NE555P.
My english is too bad

[sdesic]

That IC is not your problem ... I have TS555, TLC555 and NE555 surf pi PRO...
and they are working all with different sensitivity and power consumption.
you must look for shorts on PCB - solder bridges
