Applying a low voltage, and constant 1-2 amps to the shorted section of the board will cause the shorted component to heat up. You can sometimes feel it with your finger. But it will light up like a Christmas tree under a thermal camera. A lot faster than desoldering everything on the circuit and less risk of breaking a component.
I have to push up to 10A to light up a shorted mlcc or a internally welded fet with a 0.01°C accurate thermal Sometimes you have to shove it harder!😅 @forevertechenglish You've spent hours and plucked almost all tht components tho... 😊
Very helpful videos, thank you. Can you offer any information on mixing indoor and outdoor units of different brands? Is this possible with some brands, or do they all use proprietary communication protocols?
the amount of time spent , may just we’ll replace with new board , fast & easy , Also , it’s new board not just bandages board, last much longer and peace of mind!

Well you are right but sometimes doing it manually gives you to explore more about the circuit you are working on.
thank you very sir for sharing...

Its not possible they do have communication protocols.
@@forevertechenglish Thank you. I'm going to have to get an oscilloscope and start sniffing.

Hello, how do you clean the electronics before checking them from the protective layer?
Yep, i do if protective layer of silicon is coated on it.
what is good to clean before checking?
1:44 woah is that the power supply or something
+1
When you say voltage drop, do you have the board hooked to power because Im not seeing it plugged in
you mean to say on diode mode?
Sir Mitsubishi electric inverter split AC PCB board communication salutation
Is not dead board it just ic or igbt
Yehi video Urdu mein chahiye Bhai
Its already uploaded in Hindi/Urdu on Forever Tech.
50% Components you already removed next video.....😂😂😂
Perfect 😃
