Hola, gracias por tu respuesta. Si es un regulador de 5 V y la distribución de pines coincide, 300 mA son suficientes. Gracias, se acerca bastante.

Thanks, that's pretty close.Hola, gracias por tu respuesta. Si es un regulador de 5 V y la distribución de pines coincide, 300 mA son suficientes. Gracias, se acerca bastante.

Hello. I don't think you're a beginner. Do you have a microscope to observe the circuit? In fact, you can see many things invisible to the naked eye. As you know, transformers step up or down the voltage, which is then rectified by diodes to convert AC voltage into DC voltage, which is filtered and stabilized by capacitors, resistors, etc. You can also observe the pulses with an oscilloscope.

Hi. I would first clean the circuit board and check for any potentially sulfated traces, as well as cold solder joints and component contacts...optocouplers, etc. Best regards.Leave a comment:

I had a similar problem on an Asus board and it was the CPU not working properly. It could be an internal problem or incorrect power supply. It doesn't mean that it is the case but perhaps the error lies there.Leave a comment:

Hi.
Thank you for your reply.
The chip is quite damaged although some letters and numbers can be seen. I think it indicates AMVJ 944.Leave a comment:

Hello. I don't have the schematic, but from the photos it would be necessary to clean and release a short circuit at the input on the board for the charging base connection. Then replace these previous components and check for any other defective components. TEPSLB21E156M8R EE7 smd capacitors EE7. MTB1D7N03RH8 mosfet Q46,Q48. B28,B29,B30 ferrite choke inductors. smd capacitors 0.1u, 25v. Regards.
Hola.
No dispongo del esquema, pero por las fotos habría que realizar una limpieza y liberación de cortocircuito en la entrada en placa de la conexión de la base de carga....Leave a comment:
