Help to identify chips on Sony SRS-XB43

02-10-2025, 10:08 PM

My Sony SRS-XB43 won’t turn on, won’t charge (no LED light when plugged in to USB charger) and won’t run on batteries. I tried changing batteries but no luck.

I am trying to figure out the cause of the problem and I need help to identify two (2) ICs, which are U4 (with marking CKUCFA) and U6 (markings MPMS9428A643). I have attached a picture.

Appreciate any help or pointers.

Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB

by ugamazing

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"...

Cyberpower cps1500avr not charging batteries

by carrzkiss

Hello, all.

Cyberpower Battery Backup Unit.

I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)
When I got them in, they were not fully charged. I connected them to the UPS and waited 24 hours before connecting any networking equipment.
In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.
Checking the voltage, it was down to 22v.
I quickly removed everything...
