Can you tell me which website you used to filter for those components?Leave a comment:

I'll see if I can get it under a microscope.
Thanks for that table, that looks as though there aren't that many options actually and probably one out off all those might do the trick.

If you see any markings on it, gently wipe it with alcohol or acetone with an ear swab to wash off the varnish coating and look under a magnifying glass at what is written on it.Leave a comment:

Benq Zowie XL2540K / Power board failure / 6Pin-SOP-Chip identification
Hello everyone,
I've got a Benq power board of a XL2540K monitor which suffered from a power cut and is since defective / won't turn on. It's got obvious defects, some blown resistors, some burning around the drain pin of a MOSFET...
... and some 6-pin IC I struggle identifying, that is driving said MOSFET.
The IC is labeled as IC601, so someone with a circuit schematic could probably identify it really quick, unfortunately I can't find the schematics.
In other power boards of Benq for which I did find the schematics, IC601 is an 8-pin NCP1200 PWM controller - I suppose the function of this 6 pin chip is the same.
See the photos attached.
Pin 1 - idk, i suppose GND
Pin 2 - connected via optocoppler to low-voltage/DC side
Pin 3 - seems to be connected to GND via resistor
Pin 4 - connected via resistor to Drain of MOSFET
Pin 5 - idk, maybe VDD - i can't really see a direct connection to the plus of the rectifier
Pin 6 - connected to the gate of the MOSFET
Could it be an OB2263?
Thanks for any help,
kindly,
Sepp

Hi everyone.
Does this look fixable to you?
I don't see any blown capacitor or something that stands out.
It's not a 4k monitor, but still a good 27' fuull HD one.
Any help is much appreciated.
Thanx.... -
Long story short... ccfl's failed, bought this "ca-155" led replacement but can't identify pin/wire assignment on both power supply board and logic board since neither have anything printed over the pcb, no ENA, DIM, VCC, GND, 5v, BL-ADJ or anything like that, nothing!!!
Hello everyone and let me start with two warnings to help you understand the text wall ahead :p
first, my english is absolutely bad, mediocre at best so i apologize in advance for making your eyes bleed, you may think "then what are you doing here and not searching the help you need in some... -
Hello!
I'm trying to fix a image flickering problem (from time to time) of a BenQ GL2580H monitor. Some times the image is perfect but most of the time when you turn the monitor on the image is flickering like the refresh rate is mismatched. It flicker even without connected source. After testing of the voltages unfortunately the main board lost power - power supply board still provides steady 18.04v (pcb markings says 19v) but that voltage is lost at U705 from the pictures. The component is labeled "YVAJF" but I cannot find anything in the internet to tell me what...07-03-2020, 07:29 AM -
Hello everyone,
I have a problem with my Acer predator XB241YU screen. When I plug it in, the startup LED turns on instantly, and I can't turn off the screen without unplugging it.
After disassembly and inspection of the electronic cards I found what looks like a broken inductor, it is marked with the letter A and is at location L58.
In the first photo you can see the broken component, in the second photo you can see where it is on the board, in the third photo you can see the silkscreen and in the fourth photo you can see the identification sticker of the main board

Hey guys! my name is kyle, new to motherboard troubleshooting and a little confused still on chip identification if yall could help identify this chip..
also if you could teach me how to fish on this particular topic... i did read through the ic identification sticky, and couldnt identify this with that info... thanks!
EDIT, just realized thats a 5 and not an S in the first line... finding results for it now. cant figure out how to take down thread so im not embarrassed...
