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?
I second this question.

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.
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?
我有一台xp-760 自检的时候自动重启 是否能指导一下怎么解决
Where is your location?
I have 3 L1800 motherboards that need to be fixed.
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?

My epson l1800 too busy power blink green light too long
Some one can help me😪😪
