Don't think too complicated. You have already pointed out the problem. "Voltage rails +61.2V and -63.7V" The voltage different between +61.2V & -63.7V makes DC protection be triggered. The difference is -2.5V (61.2+(-63.7))V. When potential difference greater than 1V makes DC protection. You should CHECK THE POWER SUPPLY CONNECTED TO "AMPLIFIER SECTION" especially the "2 large capacitors with 12000uf 71V that is to measure their capacitances."Remember to disconnect the power applied to ampsection when measure +V and -V. Why? This ensures the UNBALANCE VOLTAGE of +V and -V NOT due to amp section..

Make sure there are no hidden screws , top and bottom of remote snap together, usually top snaps over bottom so you have to slide something between halves and push in on bottom or pull out on top to get them to seperate.

This is a normal condition when a capacitor or more on the power board has failed, this is a common issue however I can not assure you that this is your issue. I also advise against opening it up to work on it but if you did you want to locate any bulging or obviously distressed capacitors.(oozing liquid, extra plum-stolen, smelly or melted parts you can also look for weak spider joint as the cold air makes us keep the heat on more and along with prolonged use can weaken solider joint in some electronics good luck. https://www.6ya.com/mr.mike

“Is it possible to program a brookstone universal touch screen remote to the receiver without the factory remote?” No need to program a brookstone universal touch screen remote to the receiver. “If so how please?”Just google 'denon app download' will get help. Try to download "denon app for Android" (denon remote app) to control the amp .

check SMPS of Denon AVR X3300W located at AC in.
The voltage 5.26V may be
down. If current protect ,
check ALL components of
power amp OR replace them ALL.

I have the same issue with my DENON receiver. I know that there must be a setting in some menu someplace. But how can you read the menu when the display is too damn dim, right? I have searched through the buttons on the remote and pressed all of them after changing the batteries twice. They are either unsmart or they don';t care. Any way it sucks

The only way I know off is to unplug it. Standby simply tells you it is plugged in.

Denon PMA 250SE does not have a RIAA phono preamp.for some info about these preamp and details here;Phonopreamps.com Home PageNote: Choose a better quality regulated power supply,for these preamps. Although an updated turntable with USB can be used without the need of such RIAA phono preamp.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

How do I get it on stand by as without the receiver being on standby cannot get the Denon instruction on my TV screen. It is impossibe to do so. When in standby mode, CPU voltage supply is shorted to ground. CPU shuts down. Without receiving any signals from CPU, both HDMI input and decoder do not work. They work only working CPU is fully awake.

chek the sleep mode

Try and unplug all the cables from the unit and see if it still turns off with nothing connected. If not, connect one speaker at a time to see if there is a short

Check the speaker terminals. If they are crossed. You may have activated the overload circuits. also you may have too high ohm speakers. Connect 8 ohm speaker and try again. Make sure wires are correct + to + and - to - on both ends. If you have all this it should work. Good luck.

Not much to set up - make sure the turntable is level and stable and the tonearm adjusted to the correct playing weight for the cartridge/stylus and then connect the turntable to a suitable RIAA corrected preamp input - low impedance high sensitivity for magnetic cartridge and high impedance low sensitivity for ceramic or piezo cartridge. The speakers are best placed far enough apart for good stereo separation and on a substrate that doesn't resonate, if necessary placing them on something like concrete paving slabs or fitting them with pointed feet to bite through carpet.

Sounds like a new remote would be cheaper than repairing it. The old one could have been dropped or even had water or coffee spilled over it.

Hello, Turn off the power using. Press power simultaneously pressing TUNER PRE SET CH+ and TUNER PRE SET CH- Remove from finger from the two button when initialize the dispaly. Before restore the all setting save function of the web control.

The digital out is either a coax (TV cable) you screw on and connect to the same type connector on the receiver or it is a small square connector that requires a fiber optic cable designed for this.

The unit's manual will show you.

Hello There is always a constant 5v for the device to go to standby.and power on when you press the power button . This flashing is not to reset the device it shows that there is a problem with power supply. the regulators are burned or over voltage ... it needs service . hope this helps good luck

Hi Are you familiar with electronics? If and/or when the red led light is flashing it means the device is in protection mode. 1: check voltage regulators 5v and 12v which are the important parts to keep the device operating. 2: if there is a short circuit on the power amp, meaning the power output of the receiver. 3: check output Transistors. Hope this will help or you can give these to a technician that can help you. Good Luck

Assuming you are not a trained repair tech, I'd suggest you take the unit to an authorized Denon repair center. Ask for an estimate, hopefully no charge, so you can decide whether or not to pay to have it repaired. Do not attempt to repair it yourself.
