From what I am seeing in tube repair videos the simplest way is to get your hands on available junk boards of same brands and direct swap the components between boards. If you can get schematics it will show you the power or volts in every rail there is and this will help narrow down theproblem. It seems the smd parts will force most repair guys to just focus and be familiar with only a few types of board at first and only over time gradually increase to more different boards. It seems the manufacturer really means to make their products unservisable. More sales for them but big problem for environment

Yes its really hard to try to keep up with all the latest technology if you are a newby like me and still learning the basics. Just have to keep on reading and learning about electronics as much as i can.
Thanks Wimpie

in code book of smd another parametr is coming  with each smd data  and this is  SOT  (Small Out line Transistor )  and by measuring  each smd by a digital caliper we can find out which smd  we are facing onthe board  for example:
A2   =  HSMS- 2802   SOT 23   IS 2.9MMX 1.3MMX1.3MM   HELWETPACARD  CO.
A2 = MBT3906 DW- SOT 363   IS 2MMX1.25MMX095 MM    MOTOROLA CO,
and by comparing the two data we we can assum which transistor is which
thanks

Hi Beh,

You are right as some manufacturers could manufacture same part number but with different type of function. This really confuse us the repair tech.
