IT BLINKS PROTECT

ost models have a self-diagnosis feature to help determine shutdown problems.

To enable this feature do the following....

1) Turn the tv on and then let it shutdown
2) Press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds
3) After 5 seconds the power LED on the front panel will blink a two digit sequence.

This will commonly be one set of blinks followed by a short pause then another set of blinks.
This will repeat around five times.

1 - 2 = no error detected

2 - 1 = X-ray protect (high voltage or beam current)

2 - 2 = Short protect (short detected - commonly caused by convergence failure - to repair this check out site for a convergence kit)

2 - 3 = Deflection protect

2 - 4 = Vertical protect


Note: A constant blink on certain models will typically be caused by a fault in the DM model. To repair this check out site a "blinking green light kit"

The unit is trying to start and can not. It then enters protect mode. This means that there is a problem and a full turn on would further damage the set. It should be blinking a code, this code will tell you what the exact problem is. If you call Philips at 1-888-PHILIPS, they can tell you what is the exact problem.

To figure out the code, count the number of blinks.

If you need further help, please ask, but I can't tell you what to exactly replace without more information.

Thank you and have a good day.

Ok because your wattage is too high for the amp when adjusting a amp with speakers always start like this turn amp gain all the way down head unit bass all the way down and treb all the way up then turn on ur highest listening volume that u like then ajust amp to that hight if will stop protect from happening if continues ur sub is too many watts for amp ok

may i see a diagram showing where the ic goes?

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...

pnOne of your speakers is grounded. Start disconnecting them one by one behind the radio after it enters protect mode and then it will turn back on.

when switch ON it blinks 7time blue led - then switch OFF by SELF and blinks 8time blue led. Of-course when it switch off by self the TV swap the led from blue to red but the blinking Blue led is on the Receiver (The switcher on the TV is never blinking)

is the light blinking in a numeric pattern? like 4 blinks pause 4 blinks?

I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source)
