Power coverter to scanner failure.which unit should i buy? present one 240v 50/60hz.0.4A. output 12v.dc.i.25A


I just found my Canon 5000F scanner to have a power supply outputting 3V DC instead of 12V DC. I replaced it with a 12V DC Power Supply from Tandy rated at 1.5 amps. I had the scans getting darker by the day and sometimes completely black. Now I have great scans again. Just test the voltage at the plug that supplies the scanner for a healthy 12V DC with a multimeter.

During printing, the main thermistor detects less than 120°C/248°F for 1
sec or more continuously.
Main cause:
The fixing film unit is faulty (main thermistor fault, thermal fuse blow, fix-
ing heater fault).
Or the power supply PCB is faulty.
Or the DC controller PCB is faulty.

Gps dosen't hold a charge. ac power charge, or mobil charge


Ahh, the notorious battery problem. I had (2) units that would not charge or turn on (red light just kept flashing). I opened the unit and disconnected the battery on (1) and completely removed the leaking battery on the other since I could not find replacements batteries. The units work fine now when plugged in (AC or DC adapter of course !). Still looking for a replacement battery...

Lenovo z51t, no indication of life when power up


Try this. Turn off unit. Unplug charger. Take out battery. Replug charger - not battery. Turn on computer. If it comes on the battery has a glitch and should recover after an hour or so. If it doesn't come on, the unit needs to see a reputable computer repairperson.

Good Luck

Replace dc power jack


Hi, by dc power jack, if you mean the one at the back of your toshiba laptop, to replace, you may have to completely disassemble the unit and expose the back of the printed circuit board. This would involve removal of several small screws, panels, brackets, devices (hd. kb, cd, etc), connectors, cables. The screws would normally be small philips + but others might require a torx driver. Once the back of the main pcb is exposed, you can proceed to desolder the jack. normally there are 2 or 3 solder points. Simply insert the new jack and solder in place, reassemble and that should do the trick. However, if you are not comfortable with disaasmebly and soldering, it might be to your advantage to let somebody technically trained to perform the replacement for you. Hope this helps. Please let me know how it turns up. Regards.
