CCFL-inverter iMac 20"
Den måndag 20 april 2020 kl. 20:37:14 UTC+2 skrev Bo-Lennart:
Hi all out there. I got an old iMac 20 inch from 2007, with no backlight. I open up the iMac and found the inverter. The inverter is made by DARFON, TW. The modell is: 4H.V2471.001 I check the transistor, diods and so on. I found 2 suspect transistors.Q2 qnd Q4. Two SOT-23. They are labeled: RKM35, I don't know if it's a NPN or PNP or even a mosfet. Is there some one that have worked with this inverter, I mean in component-level. I mailed DARFON, but I got a reply from postmaster, saying that they could't deliver my mail, becouse DARFON inbox is full. Mybee they went out of busnees, and forgot to close the mail-accont. I would appriciate any help from You. Bo-Lennart Karlsson Falun, SWEDEN |
