This channel is quite educational. It amazes me how many tv's can be repaired by spending about 50cents on a part! Just need the knowledge and effort.

Add on the experience points... No one ever asked how he knew about how the TV will work without parts or how much better with parts. I personally STILL cant figure it out-huge learning curve watching these vids.

Hi, sorin I saw older video from 2017(Jvc tv lt-22dg52 no power repair) on this video you have a problem with 3 diode parallel on PSW, and to identify which one shorted you cut each time one diode and the end u are finding the faulty one. but now u are more expriance and teach us better way

People who don't understand electronic assume that a partially, or sporadically working unit is easier to fix than a completely dead unit. They couldn't be more wrong.

They don't understand the difference between a simple DC controller on, say, a toy train and a more complex supply - linear, switching, balanced. Or why that matters anyway. In the above that knowledge and methods of isolating the faulty part kept a several hundred (or more) $ (USD) TV out of the dumpster for the cost of a diode that was likely less than $20. I'm in awe of the way you work through problems and remind all of us that everything comes down to Ohm's law, Kirchoff's laws, and so on.

Recently I am retired. But I will love and watch the electronic repairs. Good luck with your Chanel. Merry Christmas Sorin. By the way I got my training in the Austria and then I moved to the Canada.

Thank you sir, you remind me my old work, as a repair technician. Nice method to find the shorted diode. I did not think that. But I have to notice that you must replace all the three diodes. They have to be from the same type and same lot also. So they have same characteristics possible. As you mention maybe the technician chooses not to equalize the three diodes so the TV come again for service after a few years.

Thanks for all your videos and taking the time to teach US. Regarding those diodes, they are schottkey diodes and even though One is marked SB and the new ones SR they are identical components. I have an electronics shop near my house in Portugal and for the SB diode they give me the SR One. Thanks again.

you can install sr5100 in this node too. these diodes differ in their operating voltage - 100 and 150 volts, respectively. but at this point the output voltage is only 5 volts, so the reverse voltage for the diode will be 40-50 volts maximum.

Great video.....I have a Samsung 75" Q70R and it went black screen while watching a movie, it flashed blue every 20 seconds, I have some knowledge in electronics so I opened it to see if it had bad capacitors. With the TV energized, I disconnected the ribon cable that goes to the main board and the screen turned blue, so I assumed it was not the damaged screen, I have been looking on ebay and I have found the original power supply parts, do you think that replacing the board will solve the problem?...thanks

It gets more difficult when a resistor opens. I just repaired a similar PS where a 2W resistor failed open but it was perfectly fine on the outside (not burnt). Had the PS in the TV fully connected and plugged into mains, and traced voltages with the aid of the PS schematics. The issue was the PS not switching although rectified mains was there.

On diode mode, aren’t good diodes supposed to show “OL” one way, and some +/- 0.500 number, the other way? At 12:10 you got a reading of 0.250V and 1.555V the other way. How is that diode not damaged. Please explain, I’m a novice. Thank you
