Hi. I saw this post, and although it's been a while, I'd like to tell you that I had a similar device, and it was a shorted CPU. The power supply, V3P3_VCCDSW, is connected via L26009, C26042, and C26043 to CPU pads 109, 110, and 191 (N39882242). I had to replace the CPU. -

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.
Google translate - Hi, thanks for your reply. If it's a 5V regulator and the pinout matches, 300mA is sufficient. Thanks, that's pretty close....Leave a comment:

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. Best regards.Leave a comment:

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:
