If it is only doing it over 30 then you need to turn down the bass level on the deck and make up for it with the subs sounds like its putting out too much juice. also if your car has a factory amp for your door speakers ect make sure that your factory speakers are the same ohms as the cd player which is 4ohm ,most fancier car speakers are 2 ohm. if that is the case the amp on the cd player is going in to protect mode to prevent frying your factory amp if you have one. check all your wiring from the cd player to the car and make sure it is all properly hooked up and there are no crosed wires. or wire hooked up incorrectly. also make sure the amp wiring kit is big enough gauge for the amp. make sure its not the amp that runs your subs that is cutting off the HU.

Mitsubishi WS48413 makes a clicking sound and turns off right away

this is a V22 chassis circa 2003/2004
you could have an issue in 1 or multiple circuits. it is key if you can determine any error code. Error code is determined by blinking LEDs on front of unit after it shuts down. It will blink a certain number of times, pause then blink another certain number of times. It repeats this cycle 5 times. fault detected
21...X-Ray protect
22...short circuit protect

23...deflection circuit
Continuous flash...most likely DM circuit.

My system shut down, my control is blinking and l can't reset either

The compressor might be blown or the refrigerant charge may be low. Sounds like a problem for an A/C mechanic.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?

This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

I have had a Kenwood VR-407 reciever for almost 9 years now but it has just started cutting off. The small power/standby light above the power button goes off when I power it up but then it shortly...

If you've already disconnected the speakers then I suspect the fault is internal on the amplifier and the unit is shutting down to protect iteself.

The fault with most amplfiers can normally be traced to blown or leading capacitors (bulge on the top or liquid around base) which can be replaced for little cost if you've got the technical ability and equipment to desolder and resolder components on a PCB.

First thing to do would be to remove the cover and check the capacitors as detailed above.

My split type 2.5hp carrier express ion shuts off (including the condenser) after five minutes of running, the indicator light blinks during this restarts again after awhile, then shuts off again...

How many times is the light blinking? Also is the light red, yellow or green? The light blinking is telling you exactly what has failed.
(# of RED blinks first)

1 High Pressure Protect
2 Indoor coil freeze protect
3 Low pressure protect

4 Compressor discharge protect

5 Low pressure/Overcurrent protect

6 Indoor-outdoor communication error
8 Hi-Temp protect
10 AC Voltage Low

Each of these has maintenance required steps to resolve the errror. Let me know how many blinks your getting...

No video or audio, but red blinking light is flashing

The Unit is Shutting itself down to protect itself from more damage, the light is blinking to let you know there is a problem, the problem could be a number of things, check the horizontal output transistor. It's a good Place to start for shut down problems

TX-DS838 shows protect and then shuts down

yes , Im afraid you have a chip gone , If you open the unit up you'll see a alloy heatsink with 4 to 8 large chips screwed to it , These are the amp drivers , In between these chips you see a smaller one (that is the protect chip),You see when things get a little hot this chip is designed to break sooner that the more expensive main amp chips , In the past ive unsoldered these and still found the amp driver bust too ,dont worry though , maplins or even farnell(cpc) on the web will supply these for less than a tenner..If you wanna test my fix then just unsolder the littlest chip on the main heatsink and it should start to work again but with NO protection(unplug it first before taking it to bits)

The receiver has gone into a protect mode because something is wrong and it shuts down to prevent further damage. Could be a power supply or output amp issue.

Getting a "Protect" message in the display which then shuts down

The speaker wires were al little frayed, so I cut and stripped new 3/8" leads and when re-inserted the receiver worked fine. The problem was a short from the frayed wires touching either the back of the receiver or some other metal near the terminal.

Can the WS-55819 be reset through a reset button?

Code 22 is short protect. Recheck your work. Did you check and replace open fuses and/or Convergence IC's. The Conv. IC's normally open at least one fuse when they go out.
