Hi I need help on this mosfet replacement SM4511NHKPC can I replace this with M3056 OR M3058 please helpToday, 06:35 PM

It's feeling like this board has a case of badcaps, instability and reboots - and not wanting to necro a a very old thread, it seems the 680uF 4V are highly suspect.
I don't really want to blanket recap everything, but maybe the others around that area could do with being changed?
Equipment: I have a temperature controlled soldering station, read the bit where it says set to 400F, don't think I would have gone that high without reading that.
Spring plunger solder sucker, and some desolder braid... and a bit of good old leaded 60/40.
PS. Additional diagnostic,...Yesterday, 12:12 PM -
There is a motherboard Gigabyte H610M S2H V2 (DDR5), I can't find boardview
Help to identify the element, marking on the element - C31PH. It stands next to the USB 3.0 and it looks like it is ESD Protect chip. We need a datasheet to this element. Maybe someone has already identified such an element. Help please.

Hi everyone!
I’m trying to diagnose (and perhaps even upgrade) this Chieftec (Delta rebrand) power supply from an old rig
The computer just stopped turning on one day. No explosions, no magic smoke, it just died.
There is no 5vsb, and nothing happens when I try to jump start it, it’s completely dead…
I took it apart and nothing looks out of the ordinary. The fuse isn’t blown and the main cap gets charged (found out the hard way lol)
The caps are mostly ltec with a samxon primary, none of which are bulging
Any ideas what I should look...01-05-2025, 04:31 PM -
Hi everyone!
I have a Zenbook 13 which could really use some more ram, as the measly 8gb it currently has is definitely not enough
I’m aware that the ram is soldered, I can do bga so it’s not an issue
The stock ram, according to cpu-z is sk hynix h9cnnnbkmmlxr-nee (16gbit, 4267 lpddr4x), presumably 4 of those
I’ve been doing some research and have found a potentially compatible sku, h9hcnnncpmmlxr-nei (32gbit, 4267 lpddr4x)
I assume I’m also going to need to configure the straps, which would require a schematic… unfortunately,...Today, 07:09 PM -
Hello, my Aunt recently gave me her broken Sony XBR-65A8G OLED after getting a replacement. It had a 4x led flash error, a replacement T-con didn't fix the error but with helpful info from this forum I found one of the smd ceramic caps on the panel pcb (C575/C378) on a 24v line was shorted to ground. I removed that cap and the tv turned on without error. It still had a black screen with the original t-con back in it, once I put the replacement t-con in it finally had a picture. After doing a panel refresh it had a very good picture but with a few vertical lines for some scenes. For owners with...Today, 04:04 PM

I am working on a Samsung un55cu7000d which has backlights and audio. There is no picture. This model does NOT have a separate TCON board. Before I order a main board I would like to try and confirm that the issue is not in the display. The ribbon cable from the main board goes directly to the display and I can then disconnect the left from the right. When I disconnect the right side the display lights up on one side but has no video being displayed. Can you all give me some guidance on how to confirm the main board is the issue.Today, 06:21 PM

Hi everyone, I have this Mac that had flaxgate problems, it was repaired, I noticed that the fans were running at maximum, I inspected and found the u 5860 torn away, recovered the chip on another main, I rebuilt the tracks, but now the fans don't turn really, if I unsolder it the fans go to max and the Mac is very slow, could I bypass this sensor? I attach the diagram+brd thanks...01-21-2025, 06:32 PM

In a poorly executed attempt to re-program BIOS, I believe I knocked off SMD resistors near the BIOS chip (MACRONIX MX25L25673G) pins 1, 2 and 5. Since the resistors were low values, I attempted to make the repairs using solder blobs. I am inexperienced and the workmanship is admittedly poor. I programmed the BIOS chip with the initial firmware read I performed. In other words, I believe the BIOS firmware currently matches what it was prior to any work I performed.

Hello, I have DA0NJSMBAD0 board that has dual charge ICs, one of them is BQ24800 and the other is ISL8238CH
Now this is a very peculiar design, they're using the BQ to charge from the main 240W power brick path, and the ISL to charge from USB-C PD port.
The ISL side works fine, but the BQ side does not. Battery is good.
