It depends. I revived my 3400 after battery leakage. Even if it looks scary it is not a zero chance to fix it. VGA and LCD are connected via different connectors. Try shining a flashlight into the center of the screen. Maybe the problem is with the backlight and you'll be able to see the...

I did it myself. It can be started without both batteries. The 24V power is soldered directly to the board because I didn't have the charger. The power board should be installed to the Mesonine connector (not shown in the photo). I also connected the button instead of the keyboard for...

Hello. Could you please provide more information about powering the laptop? I'm working on a PowerBook G3 M3553, which has a leaked PRAM battery and main battery. I cleaned it carefully, but I want to understand if the laptop can start if I connect 10.8V to the main battery pins from my bench...

Here are photos of an internal modular power supply Tamura DS205AA-EZ01A. I have not been able to find a datasheet or schematic for it :(

I am trying to get my QuickTake 150 up and running and can share some of my experiences. First of all, check to see if the gray and purple wires have power from batteries or an external power supply. If not, check fuse FU291 (if battery powered) and also diode D291, which protects against power...

wrong thread. sorry :(

Is it DDZ13B SOD-123 Zener diode 13V±2.5%, Izt=10mA, 500mW? I found it by partnumber, but SOD-123 is smalled package. And I dont understand why they used 13v zener diode because power source is 7.5v.

I also found damaged D15 diode on the back side of the main PCB. Marked like KW.

Hello. I have similar problem and broken fuse. Is it influent to starting from power supply only without battery? As I see its placed in the battery circuit and shouldn influent to starting directly from power supply. Regards.
