Integra DTR 6.3, press on button, it clicks but does not power up, only red light glows.

Probable power supply failure

http://www.integrahometheater.com/faqs.php Check the connections and try a master reset?
Perform a master reset. To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" button while doing that press the "STANDBY/ON" button. You will see the word "Clear" in the display screen and the receiver will go into standby mode.

if there is smoking near it then it needs to be professionally cleaned

You most likely have a power amp problem, disconnect all speakers and see if still does the clicking, if so you have an output amp problem

reset receiver if that does not work You will have a defective processor pcb

If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

NO sound at all? That would be odd as its internal FM receiver is independent of any user connections. I'd work on getting FM to work first, then move on to more complex issues.

The manual is here:

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [Video 1] button, press the [Standby/On] button. "Clear" will appear on the display and the AV receiver will enter Standby mode.

Dear Sir/Madam,



Thank you for contacting Top Up TV.



Please note that we are currently aware of an issue affecting some Thomson DTi6300 boxes.

If your DTR will not come out of standby and is not responding to your remote control, please try the following procedures.


Step 1: Power cycle
First of all, remove the power to the box and wait 20 seconds before restoring power.
Wait while the box tries to restart and allow 2 -3 minutes for this to complete.
Try this at least twice.
If it doesn't go to the solid green light then proceed to the next step.


Step 2: Front Panel Reset

Note: This procedure will unfortunately cause you to lose all of the recordings that you have stored on the box. You will need to be able access the back of the DTR and the front panel buttons

1. Remove power to the unit by removing the power cable from the back of the DTR.
2. Wait 20 seconds and restore the power cable while holding in the standby/power on button on the front panel of the DTR.
3. Release the standby button immediately you see a light 'blip' on the DTR front display and then immediately press the following front panel arrow buttons in sequence Up>Down>Left>Right
4.The DTR will now show the Orange LED with the Green LED flashing until the format has been completed in about 60 seconds. The DTR will return to ON automatically.
5. If requested, perform a channel scan to complete the operation.


We apologise for any inconvenience caused. Our Customer Services department can also be contacted on 08444 159 159. However, please note that we are currently experiencing high call volumes and so may not be able to answer your call as quickly as we would like.

Kind Regards,
Richard
