Troubleshoot the "No Power" Issue in CB53 Mainboard Printers, such as L1800, 1390. This issue may not stem solely from the power supply. A potential cause could be a damaged mainboard.
Begin by examining the four transistors on the power bridge (with silver head sink). If these four transistors appear functional, focus on this QF601 transistor adjacent to the USB cable socket. Testing this specific transistor is crucial, as it is key in resolving power outages, although it might not address all problems.
Package includes ONE (1) Transistor.

I had an issue with an Epson printer where it would not work at all, gave an error code and I couldn't find out what it meant and Epson wanted me to take the printer to one of their repair facilities and pay $99 for their service. I contacted BCH and explained my situation and they were very helpful and prompt in explaining what might be the problem, offering more than I expected. I very much appreciate what BCH had done for me and am completely satisfied with their service.

So far happy with the help I have received from Kevin. I am currently converting an xp15000 for sublimation and paid for a subscription (bought my guards from him as well) and even though messaged him during a holiday the day after he got right back to me, which is hard to do for a small business. I know if I need more help he’s gonna help, that’s the kind of customer service I look for.

I have been able to depend on BCH for the past two years with parts, questions and guidance. I am so thankful I found them. I have had many times I just wanted to tossy printer out the window and BCH either had what I needed or guided me to what the problem could be. They are my go to for life.
