Really good video. Another way, before cutting the track at 14:35, if you inject 1v 1A (or 2v in this case) where the removed cap was, you should feel the shorted component get warm. You can detect the warmth by thermal camera, blowing the board with freezer spay so that ice forms, or the back of your finger. 2A works better but higher you go more chance of overheating the track
Thank you for the video
Thank you for the vedio. These controller mostly have a firmware that is difficult to find for appliance. Even if the ATMEL controller is available the firmware will note be available. Thanks

program can be copied from similar model MCU
we need M64+ ADP AVR Programming Adapter Socket for ATmega64 TQFP64
@@HaseebElectronics I think frameware with this model is locked. Can't be copied
The pcbs are designed for you in a very bad way. Any fault on the output of the board is kill the microcontroller
Thank you for this video Master Haseeb! Very nice knowladge
Very good analysis. Thank you for sharing. 👍🙂
Good job .
Analytic trouble shooting found the. culprit thanks for sharing
yes
when we find the reason of dicontinuation
that is satisfying
بارك الله فيك اخي حسيب
thank you very sir for sharing this video...
Very good and useful information sir thanks for sharing this knowledge to us
best regards
Great diagnosis! I assume that these ATmega a64 microcontrollers are not replaceable. Looks like even if it were available, you would have to program it and too many pins close together to solder, although if it could be soldered, you would be the one who can do it. Take care!
Nice Investigation....Thanks Brother.....
Emeğinize sağlık hocam
Haseeb,
Thanks.
You a true master.
You are welcome
excellent analysis
👍
Teşekkürler Eşref hocam . ❤❤❤
Thank you so much for sharing this informative video keep sharing❤❤
Thank you for your important information
Very helpful, as always. So, if I replace an ic, let's say one RTL8196E, do I need to reprogram the new one in order that it can works?
Is it preprogrammed ? Do you have a "dump" of the firmware (and a programmer) to program a new one ? AS EVERY TIME efficient damage approach !

Hi Haseeb, good video, what de solder station is that you are using please. Bob
Sir what is the used of inductor in power supply secondary side and inductor calculations
So, can we replace Microcontroller?
reset pin should be connected to the +5 V thru 10K
The old/defective microcontroller likely has (or had) custom firmware/code in it. How would you get that?
BTW, my 20+ year old Kenmore washer, still has the original mechanical timer, and still works. As with all the new/newer modern cars, they’re full of these specialized electronic modules, that will soon be no longer available. What then?
PS, in the near future, I see a whole field emerging, replacing these with emulators, using Raspberry Pi or Arduino computers and hat/add on boards.
zaten baştan belli idi.
Toujour le même problème dans cette carte mère beko ( court-circuit au micro contrôleur )
What is the liquid you put on to the PCB ?
it is isopropyl alcohol 99%
👍
