Help with Tesoro Compadre

[carsten]

Hi all,

I've a Tesoro Compadre SE, with the board Rev. 4.1
When I switch it on, no sound is playing ( batterietest ), I only her a klick in the headphones from 'Power-switch'
I need a schematik or some tips, how I can troubleshoot it.
Is there a little fuse on the board ?

sorry for my bad english.

greetings Carsten

[carsten]

Any ideas are welcome,

Carsten

[kt315]

any forum in global net has a search engine. are you so beginner to begin use it?

can you give me hi resolution pics of your board from 2 sides, at sunny day light?

Hi kt315,


thanks for your reply.
Yes I've found this picture you have posted , but I thought it was for the older compadre.
I put the pictures of the two sides as attachment, hope the quality is ok.

did you check a voltage after and before LM2931 stab?

[kt315]

a schemaic above is Amigo, while some geotecher corrected it to Compadre. i can not claim you it seems all right on mistakes...

[carsten]

The voltage after and before LM2931 stab is ok.
The input is 9,5 V and output is 5 V.

[kt315]

check sound. look at circuit

(do not resolder transistors)

[carsten]

I try it tomorrow.

thanks a lot, Carsten

Most Tesoro's do nothing if the TX isn't correct.

hi kt315

I disconnect it , see the picture and put 5 V on the left side.
i've check the sound but no sound come out.
Only a klick sounds when i put 5 V on it.

Hey all,

I found the mistake :-)
The Tesoro had an loose connection / interruption in the cable to the coil.
Thanks for all help.

Carsten
