Thank you for your great explanation of how you can test LCD modules in a very short time and with little effort. That helped me alot. So I subscribed to your channel straight away.

Thanks for the explanation!! Only half of the back like on the first row is turning on, what should I do?

[@kian.smarthome]

So the back light is damaged/broken It's not worth repairing it.

Nice video I wish i could watch such video 5 years earlier 😁

How does this differ for a 14pin LED Board? I'm assuming to use the same first 3 and last 2 pins and will be testing this out later. Thank you and take care

[@kian.smarthome]

There is no difference. Thank you a lot.

[@amsndd6379]

سلام علیرضا. به ال سی دی که دارم درایور لحیم شده. برق رو با درایور بهش دادم و یه منفی هم به پایه وی او. درست کار میکنه. ولی وقتی از میکرو بهش دیتا میدم فقط ال ای دی نور روشن میشه. اگر از منفی میکرو به وی او یه جامپر بزنم تکست رو برای یه لحظه نشون میده ولی بعدش کل بلاک روشن میشه. مشکل از درایوره؟

[@kian.smarthome]

سلام، با این روش ماژول تست کردید؟ مدل ال سی دیتون برام کامنت کنید

[@mkrdeveloper]

آقا ممنون. پتانسیومتر پشت درایور رو یکم تغییر دادم درست شد.

My lcd's back light is also not turning on .Is it damaged ? Can i fix it ?

[@kian.smarthome]

Yes, it's not worth fixing it

[@abhisheks3738]

my LCD is on but not getting black boxes

[@kian.smarthome]

Check the potentiometer to increase let's say contrast.

[@ssskbslj3640]

Once connect, the first row of the LCD is visible as black square blocks. May I know how to check the second row of the LCD, pls.

[@kian.smarthome]

Does your LCD look like the one in video while testing?

[@ssskbslj3640]

@@kian.smarthome Yes

[@ssskbslj3640]

But how to carry out for the same in the second line. Any solution to test if possible pls.

[@kian.smarthome]

ممنونم کلی ی ی ی ی ی🤩🤩🤩

[@oximas-oe9vf]

I barley used it and its not turning on at all not even flinching

[@kian.smarthome]

What happened at the end?

[@oximas-oe9vf]

@@kian.smarthome the problem was with the wiring they weren't well connected, had to solder them into the LCD as the LCD I got didn't have pins pre-soldered in it

[@kian.smarthome]

@@oximas-oe9vf Kudos to you for fixing it yourself. 👌👌
