best regards and special thanks the biggest problem using these Zebra LCD connecting pads, that it creates layer of humidity while interacting with dust rust and minerals in air and humidity so using keypads and the micro movement of the PCB creates abrasive action on the meta;ic contacts of PCB and after passage time it creates cracks and disconnections sometimes the silicon rubber of keypad as do the same action with PCB tracks, especially when the remote control is used in kitchen environments, so oily fumes creates a rapid layer on PCB and gathers a rusty layer and formulates the same chemical reaction on copper traces as well
thanks a lot it is corrosion caused by the humidity and dust rust between PCB and zebra connection pad and frequently keys pressing caused the abbressive action which caused to disconnect the tracks I think so. what do you think dear?
Hey, i was looking for a possible fix for a controller of the same model and i found yours! By the way, i'm gonna try to fix it by myself, but do you have idea about what kind of electronic component is the part TX1 (behind the motherboard) and what are the specs for this part? Thanks!
please check its IR LED (turn on your mobile phone's camera. point the IR LED transmitter towards camera and press any key. on mobile screen you will red light coming out from Remote LED. if it gives indication then remote is working otherwise its LED is not transmitting signal sometimes its contacts of IR LED with PCB are dry soldered or separated. so replace it or sometimes IR LED is damaged. so replace it
Okay there are many U.S. PATENTs US4424504A - Ferrite core US3109817A for making ferrite cores EP0245083A1 A ferrite core and a transformer or inductor including it there are many many US patents and European patents to provide standardization on each item
Great video! I love to watch you solder. You have great steady hands. Entertaining to watch. I wonder what happened to the old traces? Best regards!

You always do a great job showing and explaining your repairs
it is my pleasure
Nice. Got good ideas about liquid solder, repair broken tracks etc. Thanks.
Excellent job dear friend!
Many thanks
Very good information sir thanks for sharing this knowledge to us
So nice of you
Ma Shaa Allah
You have great knowledge
Good repairing work
Very useful for most of us
thanks a lot
stay blessed

Nice tutorial sir watching here sending full support salamat sa pag share
thanks a lot dear friend
Excellent Weldon keep sharing
it is my pleasure
good evening brother 🙏 great demo very popular channel
mashaAllah very nice and beautiful sharing bhai ❤️
Thank you so much
Very good repaired. How could this damage happen? Was acid inside or leaking batteries? 🤔
thanks a lot
it is corrosion caused by the humidity and dust rust
between PCB and zebra connection pad
and frequently keys pressing caused the abbressive action which caused to disconnect the tracks
I think so.
what do you think dear?
If the infrared does not send the signal, can it be repaired?
if the microcontroller fails to generate the code, then there is no solution. just replacement is option
Your videos is very useful sir ji thanks
Most welcome
nice job brother
best regards
Microcontroller programming par bhi batayen ,,,,, jazakallahu khaira,,, 👍
yes brother
that subject is very long subject
i will try to start is soon
GOOD WORK FRIEND
great video..Thanks!

Great job.. 👍👌
Excellent
Thank you so much 😀
Very useful video

Thank you for sharing your experience and knowledge. My AC remote shows all data on lcd but doesn't respond when any button is pressed?? 🤔

Sir ferrite core transformer ke liye konse quality standerds hote he
Please guide men
please select any suitable material and calculate its Bmax and permeability value
most common is Ferrite, Mn-Zn, materials
@@HaseebElectronics I mean to ask ,ke quility SATANDERS jese ki ISI ,IEEE , standerds ke types hote he vese ferrite core transformers ke konse hote he
Okay
there are many U.S. PATENTs
US4424504A - Ferrite core
US3109817A for making ferrite cores
EP0245083A1 A ferrite core and a transformer or inductor including it
there are many many US patents and European patents to provide standardization on each item
Thank you sir
Sir sine wave inverter kistarase Kam kartehe details video chahiye
Walaikum mussalam warrohmatullahi wabarakatu thanks brother
most welcome dear brother 💗
Good job!!!!
good video
best regards and special thanks
Lk 123 brother 👍👍👍
Many many thanks
Sir that silver color crystal oscillator value plsss
Sir maike a full video of explanation of remote
Like-no buttons are working or some buttons are working
Good
thanks a lot
good
