Kenwood VR 605 power light flashes


CHECK FOR CLEARED COOLING VENTS & FOR PROPERLY WORKING COOLING FANS. THIS WILL CAUSE SHUTDOWN OF THE UNIT. IF ITS ALL CLEAR, YOU PROBABLY HAVE A POWER SUPPLY ISSUE.

Have you tried using different discs. The disk may be damaged.

Failing that, try looking at your display settings and see if everything looks like it should

I recently purchased a schumacher 410w inverter, while it came on right away and powered my electrical device the cooling fan never came on. Is the fan supposed to run all the time, once its connected.


I recently purchased a Schumaker 410/820 watt inverter. I immediately hooked it up to a brand new deep cell batery I had purchased just prior to receiving this inverter.
I plugged in several devices to make sure the inverter worked and to get some idea of what devices I can expect this unit to handle.
I noticed that the fan only ran when I plugged in a device that drew a certain amount of power from the unit. I also plugged in a CPAP unit to make sure the inverter would operate the unit properly, and noticed that the CPAP only drew 38 to 40 watts of power and the cooling fan on the converter never came on. When I plugged in an oscillating fan it drew around 128 watts from the converter and the cooling fan immediately came on when I turned the fan on. Based on that, I would assume that the cooling fan in the converter only runs when there is enough power being drawn through the inverter to cause the inverter to heat up enough to cause possible damage to or failure of the inverter. I haven't taken the time to find out the power draw at which the cooling fan will run. Hope this helps.

Sounds like the compressor may be overheating. You need to check the outdoor condenser coil it may be stopped up with dirt, in turn, overheating the compressor. The condenser coil looks like a radiator and the outdoor fan blows through it, in a sense releasing the hot air from the building. If the coil is stopped up, it can not release the heat. You can wash this coil out with a hose and sprayer. Just be careful not to get the motor wet and be sure to shut off power.

Sirpnp2 reciever gets hot and loses signal.


I had the exact same problem with Sirius radios. I bought two Kenwood DTS-7000S receivers and both were sent back for warranty. Of the two, they only fixed one but by the time I figured out the other was bad, it was out of warranty. Kenwood, along with the repair community state they do fix such units, they toss them out. The thing that gets hot hot hot is the part that receives the Sirius antenna inside your unit. If you're like me and have nothing to lose then I recommend doing some cutting with a dremel and adding a small computer fan. It just takes a light breeze to keep that part cool enough (but it does take some sort of breeze, convection is out). For a home unit, find an old A/C power supply and match it to an old computer fan of equal or less voltage. For car, find a fan that uses 12 volts or less. It's an easy fix, really!

KVT-715DVD displays call


Hi. The unit is overheating, and in most cases, depending on the car model, you will be able to fit a computer-like cooling fan underneath the receiver pointing outwards in order to help the unit cool down a little better, and prolonging the unit's operation. Usually a double-din aperture is just perfect for these improvements. If your radio mount is a single-din opening, then is gonna be a pain in the back to do something about it. Narrow spacing means overheating, especially when heat doesn't have anywhere to go, packing in the system, ergo, shutting it down for conservational reasons. Go to you nearest car audio store. They'll be able to help you out.

Start the unit and press the remote control at C if the display in the unit displays C, then turn off the unit using the remote control and plug out the ac supply. Plug the unit again and using the remote control turn on the unit. If the E4 still display there is something wrong with your air in sensor or the main board itself. Replacement of this parts needs a qualified technician.
