Hi Everyone,

My set top box has stopped working when I unplugged it and moved it over to a new cabinet. When I plugged it back in again all i get is no signal message on the tv.

The message is coming from the tv not the stb.

I've rang sky but the closest they can get a technician out is in 12 days and we don't have an analogue aerial so we have a blank screen for almost 2 weeks.

I've tried to look up info on how to reset the box but have come up with nothing. Does anyone have any ideas how to do this or what steps I can take to get a picture.

The box is a motorola

Thank you,

Kowhai7

are you sure you plugged it in the same way it was before moving it? Perhaps you plugged the video lead into the output jacks on the tv instead of the input jacks?

Can you tell us what cables you have plugged in where?

I'm pretty sure everything is in the correct place.

I have the scart out from the stb on the top scart output (marked TV). This then goes into the back of the tv into AV1, which is where it was before I moved it.

Are these the only cables that need to be connected?

that sounds right- just check to make sure that the video (yellow) is connected to the "AV1 Video In (also yellow)" on the TV.

is your SKY Satellite or UHF? you should at least get a picture on the TV showing a menu if the sat connection into the sky box is at fault.

Do you have another tv you can try maybe? or another device, e.g. dvd or video, that you can test the tv input with? that way you might be able to narrow down the problem

Yes but.

Is there power onto the STB ? Little green light ?

TV set to video mode ?

STB on, green light is showing, TV is set to AV1 - the inputs I have put the plugs to from stb. I get our signal for satellite.

Shall double check cables tonight after work but pretty sure everything is in place.

Very strange, it's doing my head in because it should just be working.

definately check that you've plugged into the correct input terminal on the tv... not sure how, but I often accidentally plug into the wrong terminal even though I could have sworn I had aimed at the correct one...

one time recently I had double and triple checked that I had plugged a subwoofer into the correct place and it wasnt till the fourth time I checked that I discovered it was on the input socket, not the output socket, even though I thought i had explicitly checked this. with so many plugs and sockets and the labels in different places on different devices i guess its easy to mix them up.

Well I've tried everything I can think of and still no luck. Over the weekend I went through all the settings again but still no picture.

So basically I'm stumped. I rang sky up and managed to get them to send and engineer out earlier to fix the problem. My guess is the stb died while being moved. Quite interested in finding out what the problem was anyhow.

While they're there I'm going to get them to set up componant cables into my new tv. Any types of stb I should ask for or are they fairly equal in performance?

Thank you for your replies, had the sky tech around this morning, and he couldn't figure out the problem.

So he installed a new stb and all is well. Got him to chuck some componant cables in as I have a new tv.

Cheers,

Sorry this is too late to be useful, but ... I don't know if you (or the SKY engineer) looked at this, but your LNB settings could have got lost in the shift. Say, for example, you have a single-throat LNB on your dish. If the box's flash memory has died or the decoder parameters file has got corrupted then, on depowering and rebooting, the decoder software will try to read the parameters file, fail and insert the new default: as there are more dual-throat LNBs out there now than single-throat it is the dual-throat frequency. The box then comes to life in 'I dunno' mode with no signal.

Hi Manaia, I have a feeling this is what happened, but in the end I got a new much smaller box which seems to change channels much faster, so it's all good :)
