You don’t need to use battery and you can leave COF connected: use your adjustable power supply, adjust voltage to the same voltage like in circulate and add current little by little and watch for elements that will heat up.
What does COF stand for? Also, when you say “... voltage like in circulate” do you mean “ voltage, like the one in the circuit”? Please clarify, I want to learn. Thank you kindly
Hi, well done, the care to disconnect COFs is a thing that i never tought, thanks, to minimize risk of trace burn instead of battery can be put bench PS with nominal voltage rising from 0Amp to the point where something get too hot, the Amp level reveal the point of overcurrent. Bye...
How to diagnose XBR49X800E Sony TV main board? I tested it with resistance and found two of pins where to connect to the power board not working, how to fix it?
Great video but I’m new to electronics, so, what does AVDD and COF stand for? Please let me know - I’m really trying to learn more about electronics. Thank you kindly
I assume I can use this method to test any LED TV and Oled tv as well ? my sony OLED TV seem to have problem with panel.. I guess it must have short somewhere cause TV to shutdown rightaway.
Is this also can ble applied for led laptop panel? I have LP133 WH1 TP D1. The laptop has broken. I powered the panel using rtd2556 but it only blinking in the dark. Like no backlight
is it necessarily a short when one of the test pad has no resistence to ground? i have a TV that boot-loops when the 2 LCD panel cabless are plugged to the motherboard (the TV can start with only 1 cable but theres no image displayed) I found 1 test pad that has no resistance to ground on both LCD panel PCBs that is called "IBC" i don't know if I should risk the method of powering the shorted area or if the problem could be comming from the TV motherboard that I could replace for 100€
It is advisable to use HALF the voltage of the particular power rail one is working on. The reason being is that other components on that power rail will be damaged by excessive voltage - one also has to consider what the limitations of the copper track itself which is being stressed at the same time - and you don't want to destroy the PCB track - it will only give you more grief than expected. Approach the subject with some thought and consideration. Think twice before doing anything.
Its a nice video. I found a short circuit in panel VCC. What component could be wrong? I measure low resistance at T200 F1, and the same at Z1 and c244 and C201
Sir good morning Sir koi video banao Jismain wify ka board kaise Pata kare kaha hai or Naya kaise lagate hai And Alexa and Google assistant ka भी kaise work karta hai TV motherboard main kaha laga hota hai Jai Hind Jai Bharat
Nice video. I have a problem with the Z1 (zener?) It´s a short circuit when I put the tester leads on each terminals. Can you tell de what kind of componen is Z1?
Man, you definitely need adjustable power supply… Everything will go much easier with it. Set voltage to 12V and you don’t need to cut power just spray some alcohol to capacitors and you will see which one is bad by evaporation of liquid…
Friends, I have an HP Compag 6710b NotBook W7 and I can't get the digital reading device to work using the AuthenTec Inc. AES2501B Driver. It is installed but how can I activate it without any software to work like the camera on the NotBook? Please help
Hello sir meri pass ek panasonic ki tv hai 40 inch usme ye innolux v390hj5-xcpe1 panal hai display me usme shooting hai right side me or VGL VGH Drop Ho Jate Hai To Shooting Kese Nikalu? Plz reply 🙏
Im a technician, very nice explanation. Good job and more power.
Very clear explanation without voice..❤❤❤❤

Excellent master!!! Very useful and clear. Thanks for sharing your experience.
Brother aap video sabse alag banate ho aap usme voltage mark lgake batate ho good video
thanks Gurdeep bhai keep watching

Mustafa, you are so great at repairing. Is it possible to train someone online from the ground electronics repairing?
Do u have training facility at your training center
Very clear steps and followed steps
Thanks
God blesssings
your aditing is awesome better than audio recorded video...awesome...👌👌👌✌️✌️✌️♥️♥️
Give more tutorials LED TV Repair , Thanks
I just suscribed to this channel couple days ago, I think its very practic and simple, just what I was specting.
very nice Tips, Keshav jee
Good job ,but if AVDD is shorted to VGL or VGH , or a short between VGL, VGH ,can you apply the same rule between these two points ,
Excellent video thank you sir from COLOMBIA👍
So nice of you
Hats off to you sir, and for your professionalism
Thanks ..................Very Nice and Usefull Video...........

Davvero un ottimo intervento sei fenomenale ...e i tuoi video sono eccellenti. Questo problema è simile anche sui tv Philips 40" o 47" ? Grazie
this is great video ... thanks for this sharing
Excellent video Friend, i like very much, congratulations from Venezuela
Fantastic tutorial
Versi good vidio, easy to learning
Sir. super good work. thank you sir

Nice but original parts hame nahi milte please buck, boost local transistor etc laga kar bataye
Sir Very informative video & very useful for repairing thanks
Fantastic job 👍🙏

cảm ơn bạn
is it necessarily a short when one of the test pad has no resistence to ground?
i have a TV that boot-loops when the 2 LCD panel cabless are plugged to the motherboard (the TV can start with only 1 cable but theres no image displayed)
I found 1 test pad that has no resistance to ground on both LCD panel PCBs that is called "IBC"
i don't know if I should risk the method of powering the shorted area or if the problem could be comming from the TV motherboard that I could replace for 100€
Amazing video. Good job.Congratulations.
Great job sir, what was the voltage applied as short killer to AVDD circuit .?
It is advisable to use HALF the voltage of the particular power rail one is working on.
The reason being is that other components on that power rail will be damaged by
excessive voltage - one also has to consider what the limitations of the copper track
itself which is being stressed at the same time - and you don't want to destroy the
PCB track - it will only give you more grief than expected.
Approach the subject with some thought and consideration.

Wow very super clear
