I'd like a little more info, but I may be able to help anyway based on my experience with these....
Does the T752 behave this way when using the source selector knob, or just the remote, or both? If the buttons work fine, but not the remote, check the batteries in the remote and try again.
Does the remote and/or the source selector knob successfully let you select other sources? If so, the next thing to check is the sea of ribbon connector cables inside. If you've never done anything like this before, PLEASE DON'T try. Not only are there so many ribbon cables inside that you could accidently disable something else, but there is enough capacitance inside that amp to give you a REALLY nasty shock, even with it unplugged and turned off.
Now, if that hasn't scared you away and you want to check, or you want to have some info for your local tech, The tuner itself is just behind the antenna plug-in on the back of the unit, in a shiny metal-shielded box. There is a wide, thin white ribbon cable running from the tuner card down to the main board underneath. Make sure both connections are firmly seated, and are in STRAIGHT, and that the bottom connector's locking clamp is in place. Oh yes, make sure to pull up on that locking clamp before re-seating the cable. The cables are fragile, prone to lose connection, especially if the receiver has been moved recently.
If re-seating the cable doesn't cure the issue, a tech will need to check the source selector chip and circuitry.

How can I connect an equalizer to my Marantz sr-66 ?

Does it have a loop through connection that is before the amplifier section of the tuner? If not I'm not sure you can. If so then you need to connect the equalizer in this section of the tuner.
The owners manual should be able to tell you more than I can find on Google

Tuner does not work on my Tuner Amplifier

Check to see if the antenna is loose. Most amplifiers will mute the output if they don't detect a strong radio signal.

If the rest of the set works fine then it is possible that the front end of the tuner is faulty. can be failure of the RF section , a possible failure of voltage to the TUNER/RADIO section . Check also if the logic switch is workingg to switch the TUNER and also if the processor is working to TUNE.

I have a DC Z-92 amplifier,PD-Z82M CD player,PLZ-92 Phono deckand F-Z92l tuner, was working fine till moved house,lost manual on how to connect it back up again,can hear very faint sound from speakers but...

first make sure you have phonograph and everything else plugged in where it belongs. or better yet unplug everything and start over. plug in just one source or just use the tuner. make sure that the speaker wires are not shorting out on the back of the amp or at the speakers. if there is a speaker switch on the front (for speaker A or Speaker B) make sure speaker A is pressed in (if you hooked up Speaker A on the back (you may not necessarily have speaker switchs.) make sure when you try the tuner that it is tuned to a good solid station. If after all of the above it still doesn't work, maybe the move caused somthing to come loose inside

When i have the stereo on radio my amp/subs work fine, but as soon as i switch the mode to USB ( built in ipod connector) it cuts out the power to the amp/subs. It only works on tuner mode (radio) why?

use the blue/white wire (amplifier remote turn on) instead of the blue wire (power antenna remote turn on) to turn your amp on. the power antenna wire shuts off when leaving tuner mode.

Sound on turntable is extremely low

As the majority is working ok and the audio section is likely to be shared with the tape, cd and tuner, the problem is most likely to be the switching to the record deck, the phono cartridge or the wiring or connections between the cartridge and amplifier.

I suggest you dust off your trusty multimeter and begin at the cartridge and work towards the amplifier.

Considering the price range of the system it is unlikely the tone arm will be fitted with a magnetic cartridge and most likely a piezo or ceramic cartridge will be fitted. If the arm is dropped onto the stylus of this type of cartridge the piezo crystal can easily be broken, often resulting in a much reduced output or no output at all. A typical output would be 500 mV to 1 volt...

My amp works on tuner but switches off when i change it to cd

The remote turn-on wire from your amplifier is connected to a blue wire behind the head unit. That's a power antenna activation wire, so the amp only turns on when the tuner is on. Switch it to a blue/white wire from the head unit instead; that should be the amp remote turn-on output.

You have one of 3 problems:1) bad solder joints in the amplifier or preamp section 2)defective output transistors/ICs in the power amp or 3)missing or incorrect voltages to the amp section. If the unit has a headphone jack plug in a headset. If you have sound then everything is OK thru the preamp section and your problem is in the power amp. Any competent repair shop should be able to solve this one easily.
