Trying to drain washer for move


Good Afternoon Jennifer, thank you for allowing me to assist you. I have located generic instructions on how to drain your washer, please follow the steps below:

1 Turn off water supply faucets.

2 Disconnect hoses from water supply and drain water from hoses.

3 Plug electrical cord into a properly grounded electrical outlet.

4 Add 1 gallon (3.8 L) nontoxic recreational vehicle (RV) antifreeze to empty wash drum. Close door.

5 Select the Spin Only cycle. Press Start and let the washer drain for 1 minute to drain out all the water.
(Not all of the RV antifreeze will be expelled.)

6 Press Cancel, unplug electrical power cord, dry off drum interior and close door.

7 Remove dispenser drawer. Drain any water in compartments and dry compartments. Replace drawer.

8 Store washer in an upright position.

9 To remove antifreeze from washer after storage, perform Clean System Cycle as described earlier.

I hope this information helps to some degree. If you have further questions, please do not hesitate to reconnect.

The power on light blinks when i turn it on like usual and the screen starts to light up and then it just shuts back off all of the sudden.


This is a common problem an a failry easy DIY fix.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Note: This particular model also has one additional step to perform besides the capacitors to fix it properly. There is some loose solder on a few parts that you will need to redo. So if you get a kit from Tv Repair Kits send them a remider that you have the HP-T4254 model so that you need the info on the other step.

HP m7640n Not powering on.‎ nothing happens when i push the power button. I have tried jumping it and the power supply is good


unplug all drives and see if you can power it on. If still no power the motherboard is bad, not sending the power on signal.

No power in computer.


First step to take is to switch out the power cord and plug it in to a different outlet than you have it in now. Just to make sure its nothing outside of your computer. If you do this and still find that there is no power, it could be one of a few things, most likely the power supply. It could be your power switch, your cmos battery or your power supply, which is what generates the power to your computer and what the plug is inserted into in the back. You may see a green light on the back of the power supply, but this does not mean that it is still good. Depending on your level of comfort and knowledge base in computers, you could replace this power supply yourself. It can be costly to take it in as the part itself can range from about $60-100+ depending on what you get put in and where you purchase the part from. This is not including the labor cost that they will charge to install it. I would be happy to walk you through the steps of changing this out if this is what you would like to do. Please let me know and I will list steps and where to look for the best priced power supply. You can also email me if that would be easier for you. Hope this helped somewhat, please let me know what our next step will be.
Thanks,
Lori

Hp pavillion m7640n has no power


It could be a power supply, but it could be a number of other hardware components too. A new power supply is less than $50, you can get them at Best Buy or Newegg.com. Any computer place can install it for you. I suggest you take it somewhere to make sure the power supply is the problem.

Hp pc m7640n won't turn on and power supply light is out


OK, this can be a hard thing to fix. Most of the time, the power supply is the first thing to go on a PC. However, when you stated that the motherboards LED came on after you unpluged the PS from the motherboard, it leads me to believe that the motherboard is the issue but the power supply might be outputting higher voltages and the motherboard might be shutting down. Since the power supply is cheaper then most motherboards, I would recommend getting a new one. Check ebay for a new power supply. It should be about $20 with shipping. If the same thing happens, then you need a new motherboard...

Replace low voltage pwer supply


To remove the low voltage power supply, Take off the side covers. the power supply is on the rear right hand side of the printer. Just remove the screw's and the cable's connected to it and your done. Don't confuse it with the Hi voltage power supply which is on the Left side of the printer as your facing it head on from the control panel.
