Fixing Burnt Transistors in Your Printer: Where to Buy Power Supply Chips

Question:

I need to know where I can purchase the power supply chip for my printer. My husband removed the printhead to clean a clogged black nozzle. After replacing it, the printer powered on but died a few minutes later.

Answer:
From your description, it sounds like the issue might be caused by burnt transistors on the mainboard. This is a common problem when there's a short or overload in the power supply system. When transistors or MOSFETs burn out, the printer will often power up but then shut off shortly after. The best way to fix this is to replace the damaged components. You can find replacement transistors or MOSFETs on our website, bchtechnologies.com. All the transistors and MOSFETs typically have an identification number, such as "Axxx," printed on them. You can search for this number on our site to find the exact part needed to fix your printer.

In some cases, the issue may not just be the power supply chip but could involve other components such as the motherboard or circuitry. If you’re not familiar with replacing these parts, I recommend watching our tutorials for detailed guidance. These replacements require specific tools and knowledge, so if you’re unsure, it might be worth getting professional help.
