Hello bro,,i have a KLBC-240DS pcb,,the problem is the output of A+ and A- no voltage can you help me solve this problem,,what steps should I do bro,,,thank you
Thank you very much for your help ! My lathe is ok, but i fear for some electronic fault, so i do greatly appreciate your sharing. Moreover, nobody seems to have the schematics of the circuit ... My best greatings ... Alessandro from Rome, Italy.
Xin chào. Lời giải thích của bạn rất hữu ích, tôi đã mở điện trở 15K x 10 watt. Tôi sẽ cài đặt một cái mới và hy vọng nó hoạt động, tôi sẽ thông báo cho bạn. Lời chào từ ARGENTINA.
Máy tiện hoạt động hoàn hảo với sự thay đổi điện trở. Cảm ơn bạn Lazy, nếu không phải do bạn thì tôi sẽ không sửa được. Nhà nhập khẩu của nước tôi đã không mang theo phần.
Lazy engineer doing a good job. I have the same problem and have used a DC speed controller to run it. Maybe I can try and check out if it is the resistor. 🦾🦾🦾🦾🦾🦾🦾
Good Job !!! i´m from Argentina, excuse me for my english. I need to know the value of SCR´s ( i supose thyristors) because in my PCB are erased. Thank you very much.
If your circuit board is identical to mine, there will be five TO-220 package components attached to the heat sink, in my case, from left to right, the first two are the main thyristor S8025C 800V/25A, one died and i had not the exact part, I used the BTA41600B 600V/40A to replace and it worked fine, that's why the first one in my video is bigger. The last 3 components are MUR1660 schottky diodes 600V/16A.
@@thelazyengineer1330 Thank you very much !!!! My lathe not working. The 15K resist become hot , the LM324 has 0 V. and de motor don´t move. If you can help me please, in my country nobody knows.....my regards jorad2000@gmail.com
@@jorgeadrianyu4371 Have you tried to change the resistor ? check if there is a visible damage in the control circuit first, in my case the 15K power resistor died and I changed it in the video as you see. It is the resistor to power the control circuit, if it dies, no voltage will be supply to the control circuit which result in 0V in the LM324.
@@thelazyengineer1330 Good job buddy Can you provide me a clear face and back photo of your board. I need to simulate one for my lathe which does not have control board. Thanks

Sorry what did you replace? Name and SPEC please

Hola hermano, lo arregló?

Good to hear that, good day my friend.
Mine also stopped today.heard a pop sound n not working anymore.. sad.

what is the value of the resistor that you replaced it?
welldone brother !
Thanks For sharing
Thank You !
Very good work.
