Check the speaker connected to the dead channel first. If it is found OK, check and replace damaged component/s at its main power amp section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

The good news is that it's in one channel, which means you have the right channel parts to compare it with. Now the bad news whatever causing it and it's likely to be a semi-conductor (transistor or IC) has to be replaced. However finding it is easier than you might think. For a start it's going to be hot to touch. And you can get get it to stop being hot, while the amps on, so correcting the fault, for a while. You do this by spraying it with Servisol Super Freezer spray. You have to have the amp running for this. Find the left channel amp and wait while it goes bad. Then spray (one at a time) any part you suspect. If the sound returns to normal, you have found the faulty part! To prove it spray the same in the right channel. That shouldn't change.
You can get the freezer spray from your local electric parts shop (such as Maplin UK).

It won't hurt to replace the Capacitors. The ones in question will be the big ones in the power supply. They will be at least 2,000UF and more likely higher. Replacing should be simple. All you need do is unsolder them and fit new ones. Sometimes they glue them in, so if you have got rid of the solder and they wont budge, that's why! Replace them with what it says on them if you can. But you can go higher. For example if it says 2,200UF 50v you can replace it with anything above that, but nothing lower. The only other problem with none direct replacement is size. So make certain it will fit in the space. Oh make certain too you get the + (on Cap) to the + on the board (though most are marked with the - symbol, so put the - to the -). Also look out for the temperture rating of them, marked (say) 85C. Again you can fit one higher, but fitting one lower will cause it to fail quicker though it will work.
If they don't solve the problem you could be looking at something on the main amp board causing it. Remember because the hum is in both channels it has to be something common to both.

If the TV has audio out jacks then you can connect them via a lead to the amp. If not the you can use a scart socket. You can get a scart plug with audio and video RCA jacks on the other end of it and connect that to the amp. If the TV has only one scart and you are using it for a video or DVD device, get a scart adapter with more than one socket.

Blingking Light or Protect usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.

I had the same problem with my subwoofer unit. I found the zener diode ZD3 was fried. The pic below shows the diode and its clearly tagged ZD3. You need a multimeter to check this before you order anything. This diode should only transmit power in one direction. Its size and spec is 18v .5w zener diode. (that's 1/2 w) It's very inexpensive and the whole repair took about an hour. This is from a Boston Acoustics subwoofer MCS 160
Ok..the procedure is easy.
1) unplug the unit and bring it to a well lit work area.
2) remove the panel from the back and locate the board that is held to the panel by 4 screws and has the ZD3 diode. The pic below shows the diode at the end of my test lead. Note the direction of this part and reinstall the new one in the same direction. Its a simple de-solder and re-solder project. I elevated the new diode about 1/8 " from the board with a small strip of copper. This acted as a heat sink during the soldering and elevated the part above the board to help it dissipate heat later when in use.
3) re-install the board and plug in all the connections.
4) this worked for me and I'm enjoying my sound system again!..good luck0482b949-8492-43a6-91df-0fb2f0e6888b.jpg

This will depend on the Blue ray player and other equipment. For a direct connection to the receiver, if your player has either type of digital audio output (coaxial or optical), get the appropriate cables. Then connect the chosen cable between the Blue ray player and the receiver. Connect the Blue ray player to the TV with an HDMI cable. See page 10 of the manual, available at http://pdfstream.manualsonline.com/6/69f43064-f593-49b8-8d4a-23174b496e65.pdf , to see the connections for the audio sources. (I'll assume your Blue ray player doesn't have component video out or you would use the component audio to the receiver.)

If your player doesn't have a digital audio output, check your TV audio output. You can get the same result by sending the videos via HDMI to the TV and using the TV audio out to the receiver. Set the audio source to TV and leave it there for both TV and Blue ray and DVD videos. (Sometimes there could be a slight delay in the audio compared with the video signal when you do this. I've never noticed it with my Blue ray player signal going to the TV and the TV digital audio out to the Denon receiver.)

If you can't send the audio out to the receiver from either your Blue ray player or TV, then you will need some sort of HDMI audio extractor. You can find models with Analog Audio Out, Digital Audio Out or both. ( https://www.amazon.com/J-Tech-Digital-Extractor-Converter-JTDAT5CH/dp/B00BIQER0E lists units with both types of audio output. One models requires a 3.5 mm to RCA audio adapter.)

I hope this helps.

After you have set your clock time simply just hold down memo button and I goes to minutes and click memo once to save your chosen time.
