Question about HP OfficeJet J4580 All-In-One InkJet Printer

What can cause the printer to not power up?

The printer was dead and I found that the adapter did not supply 32 VDC anymore. I replaced the power adapter with a new one but the printer is still dead.

Check the outlet, it could be that the outlet that supplies electricity to your printer is itself dead. try plugging something else into it.

I have replaced the power supply on my Acer Aspire X1700 computer but the new power supply acts exactly like the old. When I plug it in and turn it on the "Power Supply On" voltage goes from 5 VDC to 0 VDC...


When you have this problem on this PC, do not replace the power supply or the motherboard until you have first tried pulling out the video card. When the video card fails it can cause the x1700 to not power up. Pull the video card and see if it will power up without it.

My KP-65xbr10w appears dead no life when plugged in.


If you have no indication of power you may have lost all of the voltages to your power supply, including the 5 VDC standby voltage. I am not sure if you can get a new G board, but you should be able to get the individual components that you need. I would look for the cause of the power supply failure first, and I think I would look at your Horzontal Output Transistor. I am thinking it is Q501, Q401 or something like that. I have repaired many of these and the HOT is most likely the problem. A shorted HOT would cause the power supply fusables to blow and the entire set would appear to be dead.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Thanks for using FixYa

42" Vizio Power supply board output voltage?


The next thing I would check out is the power supply for the screen. Most manufactures call it a Backlight Inverter Board. If a part does go bad on this board, it would also cause the stand by mode or protection mode.

Same problem. red light flashes 3 times, but will not turn on.


Hi,

The blinking light means the controller QA01 in the AV_TERM system board is booting and driving the TIMER/REC RED LED light accordingly. This failure mode is true for many conditions, not exclusively for the main PS board PE0071. It could be caused by many things, LOW B, SEINE, AV_TERM, LCD, PROTECT, etc.

Specifically for PE0071+12VDC circuit failure, which is the most common , listen for the LINE relays SR80, SR81 coming online. If several (3) or more clicks are present when applying power to the TV set then suspect the +12, 20, +32 VDC inverter is faulty.

As a quick check, you can disconnect P807B. If the relays cycle every 1-2 seconds then is most definitely the +12VDC inverter. Check for voltage level at optocoupler Q881 pin 4 and this should not be cycling. This point is the VCC for the oscillator. Repair or replace board 75002913 as necessary.

TROUBLESHOOTING: (this is my own, not the OEM !, try at your own risk!)

  1. Check for LINE1 input voltage level at inverter on sheet [4].
  2. Check for LINE2 input voltage level at inverter on sheet [3].
  3. Check for STBY +5VDC & +25 VDC ( observe correct GND REF) page [4]of PE0071 POWER
  4. Check for +22 VDC out of regulator on page [3] out of Q822 Emitter
  5. Check P809B connector for :
  • P809B (12) POWER = 3.00 VDC (+/-0.2)
  • P809B (11) POWER_SIG = 0.00 VDC (HIGH to Power on TV)
  • P809B (10) PROTECT = 0.00 VDC
  • P809B (9) ACDETECT = 3.00 VDC (+/-0.2)
  1. Check for PFC_OUT = 368-371 VDC
  2. Check for +12, +20 & +32 VDC inverter page [5] of schematic manual.

For +12 VDC Inverter, suspect components:

Q880 STR-W6765 PSR (works really hot!!)
C888-C890
D884A and related switching circuit components.

Good luck,

Ineed the voltage and connector polarity for the ADS TV ELite Pro


I just found one too, same situation... no power supply. Mine has box and all. On the back of the box, it reads:
Power Supply 7.5 VDC power adapter

It doesn't say what polarity, but judging from the board... I'm gonna' say + in the center. That's what I'm gonna do.

What do you mean the power supply has been repaired and outputs 24 vdc and 12 vdc?
