Question about Edlund 270

Open Question

We have Edlund Can opener model 270. It doesn't turn with power on. We have checked the power cable and power supply - no problem. The limit switch (NO) is good. We would like to have the electrical digram of the product.

Sanyo CLT2054..........doesn`t have power.....help


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Power Supply Issues: Your Troubleshooting Guide


If the power supply shuts off unexpectedly or doesn't turn on at all, try the following steps:

  1. Check that the power supply is connected to a grounded, 3 conductor socket.
  2. Check to see if the outlet has power, by plugging another device that works in another outlet.
  3. Check the power supply cord to ensure it's not damaged.
  4. Place the power supply (transformer) at least 3.6 meters / 11.8 feet from the pool and at least 12 cm / 4 Inch above the surface (fig.1). The transformer will supply low voltage to the cleaner
  5. Uncoil the cable (fig.2)
  6. Place the unit in the water. Turn the unit side to side in the water to allow air to escape from the body and then let the cleaner sink to the bottom of the pool (fig.3). Allow wheels to soak for 15 minutes before using Mirra for the first time of the season.
  7. Then, spread the cable over the surface of the pool as evenly as possible (fig.1).
  8. Plug the cable into the power supply. Make sure the key on the plug corresponds exactly with the key slot on the socket of the power supply (fig. 4a)
  9. Plug the power supply into a grounded outlet. (fig. 4b)
  10. Press the CLEAN button and the light will glow indicating that the system is "ON." The pool cleaner should start the cleaning cycle (fig. 5). Turn the power supply on and off a few times, leaving 45 seconds in between each action, if the pool doesn't start cleaning.
  11. If problem still continues, please contact customer service or your local repair center for further assistance.

How to connect400w ate power supply to cpu


Simple change. Just turn the computer off, remove the power cord, open the case. There are 4 screws that hold the power supply in place that you will have to remove then you can remove it. What where the cables are connected to the motherboard from the old power supply because you want to connect the cables from the new power supply in the same place.

Normally there will be two cables that plug into the motherboard and they will only fit in the correct place on the board. There will be a number of cables for the hard drive and dvd drive and it doesn't matter which one you use.

My printer doesnt work it doenst switch on at all


If printer doesn't work and it doesn't switch on, I assumed that there is no power at all on the printer. Check the AC line voltage if it is correct.

Unplug the printer. Remove the LVPS/HVPS, and check the fuses for continuity.

• If open, then replace the LVPS/HVPS.
• If not open, then check the switch continuity across its conductors with the switch on.
Turn the switch off. Plug the AC line into the LVPS/HVPS, and switch unit on.

Please try reseat power cable. If this does not resolve the issue, you may need to replace the LVPS (Low voltage power supply) on your printer.

I recently bought an old dell optiplex sx 270. I


You are limited in the choices for video card The Optiplex GX270 only has a 160W power supply Not only that but because of the slim case, you're most likely limited to low profile video cards. That means the choices will be extremely limited & not very good. Even after the upgrade, you'll most likely have to stick with older games. follow this link to buy low profile video cards http://www.directron.com/lowprofile.html

Sony xplod 1200 watt amp quit no kind of protect lite on please


short answer yes... Long answer... Amp Failure: There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure. Transistor Failure/Checking Transistors: In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals. Note: I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit. It is most likely the power supply that has taken a ****.

Durabrand rb-22j1a wine cooler----no power to unit at all after being plugged in, all fuses are good.


I had this problem, no power, no light. It was the power supply output fuse. It appears to not be blown, but a continuity check across the fuse shows an open. Unsolder and replace the 5A, 250V fuse with some locally available Radio Shack parts (holder - 270-739, fuse 270-1071). Access to the power supply board is on the rear, remove the screws on the plastic plate, including the one hidden under the QC sticker. While you are in there, clean the fan and the aluminium fins on the heat sink (cools the Peltier device).

If your fuses are not blown, look at the electrolytic capacitors (the black or blue round metal cans with the aluminium X on the top) to see if they are bulging. Replace any that are bad (a common problem in switching power supplies).

Hope this helps,
