Hi Kevin and Abby, wondering if my printhead is moderately safe to retry after I replace my transitors. I wasn't having luck printing after running very many printhead cleanings, I pulled my printhead and very cautiously cleaned it and made sure there was zero dampness around the connectors or anything before putting power back to the head. Printer booted up normally it went to dock and done It's typical startup process. Then I turn the power off and the chirping started and wouldn't power back up. This printhead is only a few months old, I purchased and verified OEM from BCH, should be in decent condition I would imagine but I'm wondering if my transistors had had enough of all of the multiple cleanings? Is there a way to test a printhead for a short before putting it back in?

Anytime I change transistors on my 1400 print, it works but goes off immediately when about to print a nozzle check. What do I do in this case?

I sent my l1800 and 2 1430 mainboards in months ago. Was there any out come?

Thank You for Sharing. After replacing the transistors, what about the print head? Is it still functional or should we replace it?

I second this question. I wasn't having luck printing after running very many printhead cleanings, I pulled my printhead and very cautiously cleaned it and made sure there was zero dampness around the connectors or anything before putting power back to the head. Printer booted up normally it went to dock and done It's typical startup process. Then I turn the power off and the chirping started and wouldn't power back up.

Every time you say MOSFET transistor, I have to laugh a bit. "metal-oxide semiconductor field-effect transistor" transistor. I test semiconductors by using the pin names, eg: EBC and DGS. I am sorry buy I just couldn't follow you on how to test this board.
