Bon... ça fait un bon moment que je n'ai rien posté sur le site...
Voici comment réparer un écran d'ordinateur pour moins de 10$.
Ça s'applique à la plupars des modèles d'écran LG et probablement même à d'autres marques d'écrans...
It’s great you were able to make it work and it appeared to be a relatively simple fix considering the complexity of circuit boards. I think more electrical appliances should get repaired rather than recycled. I remember watching a video by
Julian Ilett when he did the same thing to a computer monitor. I thought it was a useful thing to know that electrolytic capacitors are the most unreliable electrical component.
Circuit boards are something I’m not good at fixing. I never know where to start or believe there is any chance of finding the fault. Until I found this video by
mikeselectricstuff. It’s quite long and a lot of it is about fire brigade thermal imaging cameras but the interesting bit is that he does some serious fault finding and circuit board repair.
Thanks for your input Oran... I'll be checking these videos during the week... It is now time to go to sleep!
You are right about capacitors... they are the main fault in many appliances... the problem is that not all electronic has a protection circuit like LCD screen (due to the risks related to the high voltage booster). Audio amplifiers per example often fry completely when their capacitors give up because there is nothing to protect the circuit from A/C current peaks...
