SOURCE: Denon S-301 video problems

Theis is a known problem by Denon, you need to get a "patch" by denon to fix the problem. If you hook up to the other video out sources there is no problem (but no HD either)

SOURCE: Power on problem

Time for a little repair here. It seems that one or more channels have developed an excessive drain on the supply, and has caused the threshold to trip and shut you down. It's more than likely shop time at this point....accordianman

SOURCE: Protector flashing red when off.

If the speaker wires are shorted, it may be in protection mode. Try turning it on with no speakers attached.

If you've already done that and still have the same problem, it's broken and you should return it.

SOURCE: unit turns on for about 5 seconds and turns off

you have shorted output transistors which is causing the unit to go into protect mode. You can try factory reset by turning off unit then holding down speaker a and b buttons then turning back on.

What is error code E000110-0105 for a Canon imageRunner C4080 copier?

Hello Sir,
This error is about yellow laser unit:
Your error code translate:

E000110 = Polygon Error
0 1 0 5
1st line: Always 0
2nd line: Station where the error occurred (1: Y, 2: M, 3: C, 4: K)
3rd line: Main unit status when the error occurred (0: Activating, 2: BD control 1, 3: BD control 2, 4: Changing the speed, 3: Operating steadily)
4th line: Polygon control status (0: Suspension, 1: FG rotation, 2: BD control 1, 3: BD control 2, 4: BD Control 3, 5: BD control 4, 6: Phase locked)

In most cases you need to replace laser unit, but first, you need to check all the connections between electronic board and laser unit.
Best Regards,

Unit will cool only for about 1 to 2 min. at start then stops cooling. The unit runs good and everything seems to work well. The unit is about 6 years old.

Hard to guess from the info given, but the best thing to tell you is pull the unit out of its case, assuming its a window unit, and garden hose and nozzle using a solid stream, keep the water off the rest of the unit, start at the top work across and work your way down. Clean it very good and if its dirty you should get back to working properly, Clean coils is the name of the game, they have to reject the heat.

Do I need to replace everything, if I buy a new garage door open.

My 15 year old system broke down due to a worn screw drive. While parts like this can be replaced, it takes a bit of guts to work inside the motor, and the circuit board. I chose to buy a new unit. New units come with all the parts ... so you don't really save much, Depending on how old the system is, the old accessories may or may not work. Even though my old 1/2 H.P. motor was a chain drive, when I bought a new screw drive the mounting parts on the ceiling and on the wall above the door were compatable. So while you get the new parts in the box, you can use the old parts if it saves you time. I was not able to save the electic eye components as the number of wire leads was slightly different in the new model. It took me and my son about 2 hours to get the old one down and the new on up. Hope that helps. (by the way, the new chain drive is quicker and quieter)

Ps3 no power

PS3 unit has fuses that probably failed. I wouldn't void the warrenty to try and change them yourself but this would be the place to start if you take it in for repair.

Unit is not locking onto signal

Check your antennae installation. Mine was frayed and I had to buy a replacement for the car.
