Turn on receiver and turns off immediately dtr-5

Sounds like an input button has been changed. Check that out first

Do a Factory reset. it's most likely a speaker setting issue. press VCR and wille holding it press the Standby button. once you see clear on the screen it is done. try it now!

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.

Had same problem. Remedy is to put digibox back to factory reset. Dis-connect from mains. Keep pressing + button on front panel as you re-connect to mains. Red LED will be on, when orange LED blinks release + button. briefly press + button. You have solid red LED and blinking red LED. Enter code 9 9 0 0, by remote blinking LED will show green. Wait a few minutes and the instalation page will appear on screen. Go to update and start as you did before and C5 should be installed. Hope that helps.

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,

Sounds like it's going in to safe mode. This can be caused by a number of things but the first thing to look at is a failed output amp.

Its possible that the Receiver is going into protection mode and possible some speaker cable might have touched the body or with each other.
Remove all inputs and outputs and then restart the receiver. If it starts then you are lucky. Connect all cable and wiring properly and ensure that they do not touch each other. You might have to reset the microprocessor if the recevier has got.

If the problem persist then let me know to further the trobleshooting.

Please do rate this solution and thanks for using FixYa.

just found this solution and it worked for me ............. though it wiped the hard drive ............ basically restores to factory settings
turn all power off and back on again press stand by button repeatedly until flashing amber light is n constant them quickly press up down left right in that order as quick as you can .............
good luck

try unplugging overnite

The amplifier blew out (probably shorted and damaged when wire was loose, and gave out under load). It won't be cheap to repair....
