Not when the so-called "refurbished" exchange still has a crappy power supply. And the "warranty" is 90 days. You don't seem to get the point that even if you were to win a legal battle with Sky, their only obligation is to supply you with a replacement which is likely to give you exactly the same problems within months or even weeks. At least one poster in this forum is on his fourth HD box! There's no "guarantee of success" there!
Yeah, right, click on my affiliate link and make me some commission! (Oh. I don't have an affiliate link.)
Buy the parts wherever you like. Several people here have advocated Maplin.
The reason I harp on about the PSU is that it seems crystal clear that ALL the Thomson boxes use capacitors which will fail so there is absolutely no point in messing with a Digibox until you've replaced them with something better. I see post after post complaining about various symptoms which are almost certainly (90%) due to the crappy power supply. But "helpful" people say "try pressing this magic button sequence" or "change the LNB" etc. while ignoring the (to me) obvious.
Here's a question: how many people here have fixed the power supply but found that it did NOT cure 90% of the symptoms?
Back in the days when I had a TV repair shop, I repaired quite a few Pace and Amstrad analogue boxes. I'd
always replace the PSU capacitors before even trying to diagnose the fault cause. There was simply no point in wasting time trying to locate a mysterious fault when experience told me that a low voltage or electrically "noisy" power supply could produce an enormous number of different symptoms. I'd get customers complaining that I'd charged them for a power supply repair when they'd brought the box in with a "faulty tuner"!
Nothing has changed in twenty years. Manufacturers still use crappy capacitors and users still can't understand why a power supply can cause a "tuner fault" or whatever.
