2+ year old TV with many (720? 65" version has 720) mini LED dimming zones. TV boots, has sound, panel picture can be seen with flashlight. No backlight. No TV model sticker on rear panel (Maybe Samsung service removed it, read below). Found the model # through the PSU and zoned LED driver board numbers.
PSU has a click near LED output circuit at 1 second interval, sounded like the 4x barrier rectifier area. Protective pastic liner under PSU shows heat signature on the Schottky Barrier Rectifier in this circuit. Found a shorted diode (2 diode per rectifier, failed rectifier labled... -

Hello everyone,
I'm trying to fix up my battery charger. Where I found a dead schottky rectifier.
This is the dead component PTR30L120CTF:
PTR30L120CTF datasheet(1/7 Pages) PFC | 30A 120V HPTR Schottky Rectifier (alldatasheet.com)
And I have a spare 30CPQ150:
30CPQ150 datasheet(1/5 Pages) IRF | SCHOTTKY RECTIFIER (alldatasheet.com)
Can I use this diode as a replacement or if not, can you recommend me a proper replacement?
I cannot find the exact unit anywhere besides aliexpress and such.
Thank you guys!

Lenovo Legion 5 15ARH05H, NM-D281 Rev 1.0, "BIInitializeLibrary failed 0xc0000185" and bios freezingDear members,

Hey guys,
I've got a Surface Laptop 1769 (the nasty cloth type palmrest) which has a failed 512GB Samsung PM971 (KUS040202M-B000).
These are on BGA291, but I don't know which is equivalent to KUS040202M-B000.
AliExpress has this but it's expensive.
Can anyone help me find a reasonably prices equivalent which I can use as a replacement ?
Or which NVMe can I remove it from ?02-17-2025, 04:02 PM
