Pace box wont boot

[Trafpol]

Hi Im new but already I have a question which I know someone can answer.
I have a PACE box 4000 model and Im trying to boot into engineers mode. The usual method of holding down up/down keys when powering up isnt having any effect. Display just shows "PACE" . Anyone have any ideas?

power up dht holding in the standby button
wait untill okay appears in the display
release standby button 0000 appears in display
press the following buttons in sequence:
tv guide-interactive-tv guide-tv
2321 should appear in the display
press the ok button and immediately hold in the up & down menu buttons
4 dashes will appear in the display
the dht should then go into diagnostic screens

Hi

I have a 4001n Pace box that just has 0 channel displayed no others. The only way I can boot up my box is if when powering up I hold the the 2 channel keys simultaneously and wait until I see boot then let go.

I have removed the jumpers on the battery for a few minutes then replaced hoping it would scan for channels but no luck. Any ideas. Cheers
