Good afternoon, does anyone know the difference between these ECs, my original EC is the NPCE781LA0DX for a toshiba satellite A505-SP7913A. I can get an EC in Argentina that is practically the same, just change the letter L with E. Does anyone know the meaning of each letter? Question for experts hehe

Got a CA02 version without all the boards. LCD panel not cracked but unknown condition. Backlight seems to work with LED tester.
Board sets cost 2/3 price of the TV. Found a FA01 version board set for good price. ShopJimmy doesn't show FA01 CA02 as interchangeable. main board numbers between 2 versions are different but t-con to panel connection appears identical. LCD panel PN is 1 letter different.
Version CA02
LCD = CY-NR075FGHV1H (letter H)
main = BN94-14163F (shopjimmy link)
Version FA01
LCD = CY-N... -
Hello,
I'm posting this here because I didn't see an "(Help) Identify(ing) Components"/ "Components (Information)" etc. Thread.
I'm repairing a brushless DC motor board, nothing critical just a simple power board. One high side Mosfet and one low side Mosfet were found short (cross phases), and I didn't have continuity through the positive supply. Found two components that were not conducting. Their appearance was similar to capacitors, however they contained some writing, and they were online with the primary power bus. So I determined they were... -

Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...
