There are 3 chips marked as "G01H". Any idea what they might be?

"G0" is a digital PNP transistor pair. Does it fit the application?

Yes,,,,,,other DCC decoders use similar chips. I'll measure them out of the PCB.........I wasn't able to get 44k ohms between base-emiter. It might be faulty. Thanks for the feedback.Comment

I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"... -
Hi,
I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green
For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct... -
Hello dear badcappers!
The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?
Backstory:
After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.
If there is a way to narrow down which memory module is faulty it would make my life much... -
Hello again! (People are likely going to get tired of seeing posts from me lol)
I'd like to try and compile a list of known bad AMD/ATI Chipsets and graphics processors.
While I do not possess the knowledge of some of the brilliant minds on this forum, I can at least mention a few chips I've encountered as being troublesome.
1. ATI 216-0752001 (RS880M/RX280M) found inside 2 HP laptops, one I've since deemed screwed, and swapped the board to an intel one, the other HP seems to be less hateful and runs fine.
2. ATI Mobility Radeon X1600 and the... -
Hello,
Device: PocketBook InkPad 3
Mainboard: XRZ_E091_PB740-VTTOA-V1.1 / 2017-10-12
I'm replacing the broken microUSB connector on this e-reader, and during inspection after desoldering, I noticed a loose black SMD component marked "CT". One of them was torn off along with the pad, while the other one (marked in the photo) is still in place.
I would appreciate help identifying this component.
Measuring the loose component with a multimeter gives 5.84 MĪ© in both directions, while the one still on the board shows no measurable...
