These modules are available with local shops! Many thanks for your comments!

I never used such modules in my repair work. Where do you buy them from

FR207 is a fast Rectifier diode. I connected it to secondary of Transformer in place of the SMD diode. Many thanks for your comments!

Your guess is correct. The schematic provided on the module by Chinese manufacturer shows it as Blue. Well, I never noticed it until you pointed out! Many thanks for your Sherlock Holmes observation and comments! (You might say elementary, Watson, elementary!) (LOL)

And I guess that the blue wire in the schematic was your green wire here which you did not need in this case?
