Also, D136 is OL as well as the ZP diod. The resistor next to the ZP still reads good at 500 ohms.

It took forever to get the white adhesive off the pcb, but here is the photos. There is still more white adhesive on the reverse side but here is photos of what I have so far....

Checked it again with new batteries still the same output from 34.85 to 34.88V DC pretty stable at these readings. If there is something else you would like to see just let me know and I will post it here. I am open to checking anything and everything at this point.

Help!

I am trying to repair my Alienware M18r1 AC/DC power adapter. It is currently putting out 34V DC when it is supposed to put out 19.5V. This is preventing the battery from charging because it is triggering the safety protection. It is also causing it to throttle the processor performance. The adapter information is as follows:

Dell P/N: XM3C3
REF. NO.: ADP-330AB B
MODEL: DA330PM111

I believe the problem is with the below pictured regulators. The one with the markings "ZP" I have identified as a Central Semiconductor CMDZ16L...

Hello Everyone,

I am working on a Samsung MX-JS9500 Giga Party Stereo System. I am specifically insearch of the Main Board Schematics.

[B][U]The Problem:[/U][/B]
The unit is not powering up the Bluetooth or CD player. The rest of the unit acts like everything is working fine. When you press the bluetooth button the unit says "please wait" while it tries to start the bluetooth but it never starts. The same thing happens with the CD player. There is no response it will not open the tray or close it. It just says "Loading."
