Sky + HD Problem
Thought the collective of brilliant minds on here may be able to shed some light in this.....
Been having a few problems with my Sky + box (was 2nd hand when i got it a couple of years ago) sound has disappeared a few times, cured by a full
reset, so thought i'd pick up a spare box just incase the + box failed.
Bought a 2nd hand HD box - Thompson one (just to use on std sky subs and not the HD) however just plugged it all up and have a problem......
Some of the channels have very poor reception (all pixalated) all of the + features work OK and everything else appears to be fine (I like the new EPG
on the HD box), have done a full reset etc and spoken to sky incase I needed to update the viewing card.
The chap at Sky thought i should try using an HDMI cable instead of the scart, but failing that the box may be screwed....
Any pearls of wisdom? , already mailed the seller on ebay so if the worst comes to the worst i'll get ebay and paypal to get me my £ back as it
was advertised as fully operational....
Ta for any help.

Sounds like a problem before the box if a different box hasn't fixed it, is the problem the same with both dishes? When did it start happening?
The dish hasnt been knocked out of alignment by heavy snow? Unlikely but if the fixings weren't very tight it could happen.
With digital a poor signal usual means pixelation and dodgy sound, I think there is a signal strength indicator in the setup menu somewhere, failing
that you can get a inline signal strength gauge for setting dishes up. After checking your dish maybe check the wires havent frayed anywhere.
Just re read your post and im guessing that your original + box is fine, its just the HD box that is playing up.

As already said above, check the signal strength in the 'services' section and that will give you an idea of where the fault lies. If you
can switch to HDMI you will notice a definite improvement in quality too.

When thinking outside the box doesn't work any more, it's time to build a new box

As its a Thomson box i'd say its the PSU that's causing the problem. Its a well known design flaw. The capacitors on the psu board are not
upto the job, bulge and cause all sorts of errors including pixelation. There are upgrade kits you can buy on ebay to fix them yourself or complete
psu boards for a full replacement.
I've got 2 thomson hd boxes myself and one's had the upgrade which cured it, the other is waiting for it (reports no signal) although fine
if I put the others psu in it.
Whats the signal strength and quality as reported in the signal test section btw?

Edit : Took so long typing that others already asked the signal strength question

Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

As has been said, it probably needs the caps replacing in the PSU. I'm pretty handy with a soldering iron and only 10 mins down the road from
you if you want it done. You'll need to buy the parts though - loads of places sell them as a kit.

I had a tompson box and the tuner unit in it went. caused exactly the same symptoms you describe. ordered a new unit off the net for about £15
desoldered the pins on the old one then soldered in the new one. fired it up problem solved.

Thanks guys, knew you could help.
I'm in talks with the seller at the mo if i need to i'll either get an exchange PSU or buy a bag of capacitors and break out the soldering
iron, (built a megasquirt so this should be easy!) Thanks for the offer Chris, if i need help i'll let you know, where abouts are you then?
Cheers
Ash
