I would like to congratulate you on a very well written and detailed report. I spent my entire work life (1968 - 2022) in the electronics field and it is not very often that you find such detailed and properly explained articles in the media. I would like to read more of your articles.

It depends on the circuit used. In Samsung TVs and perhaps in monitors too, backlight getting on is independent. But after switching on, the on/off control takes over and it is done through the second optocoupler. Many thanks for your comments and encouragement.

We all need to impart our knowledge and share our ideas and experiences with all other like-minded people across the globe! That's the minimum thing one can do during one's lifetime and the effect of such actions is the only one that we might carry over to the next life!

The universal board will work on LED only. For LCD, we need to use the set's LCD driver. Many thanks, dear friend!

These boards are very freely available in our country. I have no idea about the DVB-T1 or T2 you are referring to! The knowledge about Samsung getting automatically on is from my techie friends. Many thanks for your expert comments!

We technicians should get self-trained to overcome such fears! Just go ahead and try on defective scraps and get practice. It will be alright then, when needed! Many thanks!
