Re: Dell ONE All In One Computer
Hi everyone I also have an XPS One A2010 which powers on, I can hear the post beep, blue leds switch on etc... however I have no video/lcd does not power on at all. I've been told this is most probably due to the power supply. Inverter seems fine, I've shined a light onto the LCD and there is absoluteley nothing... its not even turning on. I've done some voltage readouts on my PSU using a multimeter and this is what I found:
4 Yellows - All showing steady 12V
1 Blue - Showing steady 12V
1 Purple - Steady 5V
1 Grey - Steady 4.85V (bit low? but within tolerance I think.... power ON/OK)
1 white - Fluctuates between -.7 and -.9 (not sure what this cable does though, could be signal...)
1 Brown - Erratic fluctuation between 2 - 2.2V I'm guessing maybe this is the problem?
I haven't found aspec sheet for this PSU so unsure if the voltages are within tolerance.... What would I have to replace within the PSU in order to get the correct voltages? Thanks...
