Hi again,
i have just finished to assembly everything, and now I am stuck at the 11th step…
When I turn on the Shruthi, it doesn’t start and the 7805 is overheating. I am using a 12V - 2A DC , do you need a picture of anything ?
I don’t understant where is the problem…
Have you performed the voltage test on the filter board?
I assume you are at Step 11 of the Digital Board.
First, did you perform the Power SupplyTest at Step 5 of the Instructions?
If not, do it now!
The 7805 get so hot because it has to deliver to much current - check for shorts!
Yes and everything was right. between 5 and 5.1V and 5/-5,1 , do I didn’t have any problems at this time :/
I have check and there is not shorts on the both boards !
hahaha fcd72 ^^
Yes everything is right with solderings on the mkII, and seems same on the control board… Not any shorts !
Do you want a picture of the boards ?
How did you check this?
If it gets to hot there is a short. Perform just the Power tests to see wether it is on the Filter or the Digital Board.
EDIT:
Pads at the Caps for C14 look suspicious for example…
I have done the Power test on the SMR4 board : everything is right. So it comes when I plug the control card on the SMR4. What must I do now ?
Check for shorts on the Control Board if you are shure the Filter is OK (which means the 7805 doesnt get hot when plugged in for prolonged time.).
Post a Pic of Both sides, maybe we can spot something.
Here they are 
What’s that big white blob on the bottom left pins of IC 2?
Right ! Everything is good now
