Re: need IC datasheet CH29U-2131
That looks like a "fairchild" chip. I assume you've googled for it?
Maybe contact the manufacturer.
What is this going in to?
I have alot of circuit boards in my parts bin.Disclaimer: Don't trust a thing I say-I am frequently wrong!!!
I have tons of spare parts, some used, some N.O.S. ham transistors and caps. Message me if you need any parts.
Some of the things I've fixed:
60" Vizio-bad LED's. iBook G4: Resoldered VCC Plug. Geo Tracker ECU: Swollen / Leaking capacitors. Windows Laptop: Soldered broken LVDS wires. Dryer: Burned contact on temp switch. Oven in R.V.: Bad contacts in relays-Exploded by the looks of them! Samsung Oven: Burned contacts on Relays. MSI Motherboard: BSOD-Swollen capacitors, bad graphics card, Moved SATA Input from SATA 1 to SATA 2 plug

Computer in question : Razer Blade 15 2020 Base Model
Model# RZ09-03286E22
BIOS CHIP: WINBOND W25Q128BV
What I'm trying to accomplish:
I want the computer to properly boot with an external display with the attached display disconnected from the motherboard. I have a CH341A programmer and full capability of modifying the BIOS easily. I Have tried various setting changes to no Avail.
What I've tried thus far: Too much to note and I really dont remember everything I changed but here it goes.
W/Stock BIOS - 1.06:

Hi, pulled this component, (I'm assuming it's a MosFET) from an LED COB video light. Im trying to find the datasheet so I can find an equivalent replacement but no luck. Any assistance with the datasheet would be appreciated.
Failing that, a way to pick a suitable replacement component? If it's indeed a switching fet, I'm assuming I might need to measure the switching clock frequency and find a component that meets the power capacity?
Its a pair of them driving a 130w Light. Takes in 19volts. I can borrow a scope to measure the switching freq.... -
I got a dead HD6950 on Ebay to try my luck and repair it. There were a few broken off capacitors that I already replaced.
Measuring the PCI-E lanes I got somewhat weird measurements, the gpu might or might not be dead.
If I plug the GPU in, the core heats up and I also get VCore but on two inductors that measure 16 and 60 Ohms respectively (Memory and PEX I guess) there is no voltage.
On one of the two buck-controllers (APW7165) the enable pin is pulled to GND and the other controller I just cannot find a datasheet for.
So if anyone has a datasheet or at least... -
TE Circuit Protection offers the widest selection of surface-mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.
TE Circuit Protection also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements, including Telcordia, GR-1089,...10-07-2024, 06:07 AM -
A few days ago,I destroyed one of my japanese retro game console by pluging it to 220v outlet.
https://www.badcaps.net/forum/troubl...e-been-blew-up
and I finally fixed​ this retro game console by soldering varistor and glass fuse.
But I noticed that When I measure voltage of PSU's 5pin connector, it is 8.80-9.07v, 5.13v,3.40-3.48v,GND,GND instead of its rated voltage of 9v 5v 3v GND GND.
I have spare console...
