Question about NAD T743 Receiver

Open Question

Controls of NAD T743 block when using the remote control. The T743 works fine until a (any) remote control is used. I can operate all controls on the front panel of the T743, but when an IR remote is used the display turns black. Also it will no longer respond to the controls on the front panel. No volume, no on/off button, nothing. It just continues doing what it is doing, until I break the power with the button on the back panel. When powering on it works fine again, as long as nobody uses any remote control in the vicinity of my T743.

SOURCE: My NAD T743 will not switch on

Hi, have you checked the power button in the back to see if it got pressed by accident? It's a round button located right under the speaker inputs in the back.

I have an HTR-2 NAD remote. All the buttons except for the ON button are working. is there anyway to fix this?


Remote controls have an operating code which entered right will cause all functions to work. However if you were given the wrong remote or it doesn't have the right code, certain buttons will not work.

Check that the appliance it operates is the right model for the remote. Some remotes will allow reprograming others are fixed. If you can reprogram it will be just a question of finding out which code the amp uses and entering that. You can search online for the codes for your model.

It's not uncommon for the wrong remote to be sent out when first sold. Some people don't know it's wrong as the remote works nearly all the functions, just not all.

What are the remote codes for Sony RM-EZ4 / Haier TV, Comcast Xfinity cable box?


Follow these steps to program the remote control.

  1. Turn on the component to be programmed.
  2. Press the SET button.
  3. On the remote control, press the appropriate component button.
  4. Using the number pad, enter the component's manufacturer code.
  5. NOTE: If more than one code number is listed for the manufacturer, repeat the procedure, entering one code at a time until you find one that works.

  6. Press the ENT button.
  7. Point the remote control at the component.
  8. Press the POWER button to verify operation.
Comcast offers several remote controls. The type of remote you get depends on the device you're using. Some Comcast remote controls are multi-device or universal remotes, while others only control the set top box and TV.

They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

A heat sink is just a finned heat-conducting device for radiating heat to the air which should be flowing freely through the unit's ventilation holes. It can't break in normal use. But it CAN get clogged with dust reducing its effectiveness.

"Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within 25 feet/8 meters, between the receiver's front panel and your primary listening/viewing position-this will ensure reliable infrared remote control communications. The T 743 generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the T 743 atop other components, but the reverse usually should be avoided. Nonetheless, it is generally preferable that the T 743 stand alone. It is especially important that sufficient ventilation be provided; if you are contemplating locating the T 743 within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow."

If you're lucky, you haven't finally toasted it. If you have, a hands on tech will need to sniff sround (literally) to find the dead component(s).

Fpa lock on how do i get this offf


hello Lock/Unlock Parental Controls
Selecting this option lets you lock and unlock parental controls settings
using a password.
If you do not lock parental controls, none of the settings for V-Chip,
Channel Block, or Front Panel Block will take effect.
If you forget your password, press the MENU button, then select Parental
Control
(the password entry screen appears). Simultaneously press and
hold CH+ and VOL+ on the front panel for 8 seconds. Parental Controls
unlock and the Parental Control menu appears. You can enter a new
password by locking the Parental Controls again.
Front Panel Block
Selecting this option lets you block (disable) or unblock (enable) the TV’s
front panel. The remote still tunes to any channel. When using this as a
Parental Control method, remove access to any remote that is capable of
operating the television while you have the front panel blocked.
Don’t forget to lock parental controls after you change the status. If you
don’t, the front panel block will not take effect .if this don't work get back to me i've got manual good luck

Using NAD t743 with Panasonic DMP-BD55


The reciever you have has 5.1 inputs at the backof it.The only way to get Dolby True HD and DTS HD is to run the 7.1 analog out from the bd55 to the nad. You'll have to leave the 2 rear surround open on the bd55 leaving the remaining 6 connected to the nad. The digital coax and the optical will not transmit the hd data, only the analog out will. Run a hdmi right to your HD tv for picture bypassing your amp. this will workfine and you'll have the audio you want. You,ll have to change the input settings for dvd in your amp to 5.1 to recieve the audio.

Turns itself off


NAD Technical Bulletin T743-H2005-06 describes the problem "Unit may shut down, shortly after turn on".  Reason: There is a diode on the standby board that maybe operating intermittently.  Solution: Locate and identify D756 on the standby board.  Change only if the diode is a 1N4148.  Change from a 1N4148 to a 1N4004 or equivalent.  
It is located near a transformer and some fuses.

Does not respond to remote control


I have had the T743 for about three years now. The first unit which I got from the local shop was doing exactily like your described after couple of minutes use. Well, I took is back and got a new one covered by the warranty.

Unfortunately I never got any explanation to this problem from my local shop or anywhere else, so I guess the only way is to contact your local shop.
