Hi all, The picture attached is a M1212 CRT attached to a Performa 6300 CD. I have verified the Performa will drive a VGA monitor correctly (with one of those dip-switch adapters) so I believe this is a problem with the M1212 itself. I have opened it up and no capacitors are bulging or blown...

Thanks indibit! Do you have a surface mount soldering set up with a hot plate? Or did you manage to make these modifications with just a regular soldering iron. Evan talks about how hard it is to get the board hot enough. I was going to try with just a soldering station since the SMD parts are...

someone on Reddit answered my question: Panasonic TPB Series 150uF 6.3V Polymer Capacitor: https://docs.rs-online.com/4155/0900766b814dbdb1.pdf Kemet PS/K Series Neocapacitor, jE8 = 150uF 6.3V...

Lots of threads about VRM troubleshooting and some upgrades you can do on an existing card with new MOSFETS etc.

Look for a replacement for my blown C3. It looks to be a 150 uF 6.3v capacitor? Does anyone have a digikey/mouser/newark link for the proper replacement? Tested out my blown VRM and the 5v rail is shorted. Not sure which MOSFET is bad since they are in shorted with a DMM. Hopefully it didn't...

Thanks for the reply JDW. I believe evanboonie's start of a VRM replacement has the pinouts for the connector but need to reinstall Kicad to check.

Any suggestions for the best way to test an original VRM board? I have two replacements now for my “magic smoke” VRM I posted a bit ago. Should I look for shorts on the connector voltage pins in case there is a short on the motherboard? Or any way to test a board in isolation? I’d rather not...

A mystery! What adapter(s) are you using and what exact DVD drive did you replace it with?

My VRM in a second cube I have is pretty toasty. Some bad soldering reflow and C3 is blown. This was in a cube I just picked up and magic smoke appeared from somewhere when I plugged it in. Is there a guide to test these somehow or troubleshoot bad components? Or does someone rebuild these? I'm...

Yes. 9 in master and DVD in slave - DVD does not show up. 9 in slave and DVD in master - DVD does not show up. I verified that the master/slave pin on the 9 enclosure does change it's device ID in "More Info" but somehow blocks access to the DVD which is weird.

Do you have a suggestion that is known to work? My #8 item is a 2.5” IDE to MSATA enclosure so nearly the same as an IDE SSD I would think. And for some unexplained reason it blocks access to the DVD-ROM. i don’t believe there are any 3.5” IDE SSDs(???) so you will need a 3.5 to 2.5 adapter...

This is a pic of various hard drives and adapters I've tried with my cube over the past month or so. Here's a writeup I did for another site: I picked up G4 cube about a month ago with no hard drive. Here’s my saga for getting an SSD to fit in the limited space with the original cable and...
