Parasuraman S: You are very thorough and cover all the bases, even giving the urls
to the previous episodes of this dvd player. Your explanations are always full of procedures and techniques that interest most technicians. Thanks for your interesting repairs, we enjoy very much.

There is already a book published by Jestine Yong on alternative power supplies, I think! I remember to have bought one. Many thanks for your keen observations, comments and opinions!

Thanks for the appreciated summary on these in previous repairs used universal power modules Parasuraman. I certainly will look those up to see if they clearify in how to use the yet unknown to me other power modules. You probably again could write a good book about this subject alone! And I certainly would buy it if you had!

In reply to Imoudu.O.

This was a DVD player, which did not have an amp inside. That was added during its first visit of SMPS breakdown. The module available in the market is three wire, Red-Black & Green. Normally the Green wire is ignored. Kindly read my reply to Albert van Bemmelen in which I have references of old articles on modules. Secondly, due to advancement in technology, I tried to revive the original SMPS once again. That is why I had to make several attempts. Hope this helps!
