An Easy Fix to a Professional Audio Device. Model TASCAM
An American guy brought his professional device for repair. The customer explained that the device was deserted for a long time. When he tried to use it again, it did not work.
I have opened and worked on these devices before but the older versions. This is an excellent device and many audio professionals use them because they are very small and easy to carry and operate.
I added fresh new batteries to the device and as expected, the fault remained.
Taking the back cover off was easy and I could see inside the device. As I scanned the device under the microscope looking for any burnt components, I found none.
I traced the main line of the batteries inside the device and that lead me to go under the Mic’s input section. Once I took that off and checked for faulty components, again I found none.
I spent about an hour or so looking for bad component and finally I gave up and started looking for information about it over the net.
The first search I did lead me to an easy answer to the problem. According to the information that I got over the internet, if the device was deserted for long period of time (the customer confirmed that) , it goes though sleep mode and If the operator wanted to use it again, he has to press the power button twice, one short press and then a long press till it comes on.
After all this time I spent trying to find out what was wrong with it, I was willing to give it a try.
To my surprise, the method actually worked. That is a new experience for me and I am sharing it with you guys.
Mission Accomplished.

Es verdad lo que una vez mi maestro me dijo: lo más obvio resulta lo mejor. Es tan importante comenzar con lo sencillo en estos casos para después profundizar en lo complicado. A no ser que se quiera obtener experiencias nuevas, como en este caso.
Felicidades!
===================================================
It is true what my teacher once told me: the most obvious is the best. It is so important to start with the simple in these cases and then delve into the complicated. Unless you want to get new experiences, as in this case.
Congratulations!

Gilberto: as long as you know the basics of electronics you can start with easy things and then develop into bigger harder things. for me it started a hobby and then I developed it into business. it is good to enjoy what you are doing otherwise you are wasting your time. have a blessed day
