This is a big chance to get my own work on it for a minimum price.

I have been doing service for all kind of industrial electronics for the last 32 years. My method is more than 90% effective and this is what I do for Living.

Drawing wiring and detailed diagrams is a simple thing but is quite tedious and long hours to consider.

My experience on that field is needed if my customers requires to get their stuffs working fast and seriously.

Nobody can fix a high percent of stuffs if doesn´t know how they work. As simple as that!

So I had to get my own diagramming software and repairing organizing software as well. History, pictures and that kind of things that takes a little more time to fill out but it certainly will help a lot in the next time to work on it.

Here is the deal:

I FINALLY DECIDED TO SHARE MY EXCLUSIVE WORKING BIT BY BIT FOR A LITTLE COST AND HELP OTHERS TO MAKE THEIR LIVING TOO.

So, if you are skilled for a little of electronics, then save a bunch of dollars to replace your DOOR OPENER or SPARES and long lead time involved as well.

My last experience with this called 0.5HP CHAMBERLAIN P# 41A4201-3A iDOOR OPENER and its inside controller & device electronic boards, similar to, and used in other SEARS CRAFTSMAN, LIFTMASTER and other DOOR OPENERS. 

I've been located in Mexico for a long time and the market is growing up for the whole industry. My customers do not have to pay several thousands of dollars to get their machines working up again and I got rewarded not only for the money they pay me, but the great an kind treatment that have for me showing their gratitude and pleasent feeling because of the attention during the service.

So the last experience is about the fixing of dead output power in one of these which isn't the one of my hardest repaired I have ever made but ultrasonics is a serious thing to diaagnose and the ptoblem was a simple task with instrumentation around.
