Samsung S4 mini GT-i9195 -cracked screen

I take on a phone screen replacement

I’ve never replaced a phone screen before, but since there’s a wide range of spares at reasonable prices available out there, I decided to take on this repair for a friend.  The screens on these and other smart phones are fragile.  They are made of finely machined glass, made to extremely high tolerances and therefore susceptible to damage from knocks and scrapes.  At this point usually, I might whinge on about how manufacturers do this deliberately to some extent, to bolster built-in obsolescence, but on this occasion, the break was due to the owner falling off his bike (off-road) and the phone hitting the deck, while in his pocket.  I’m amazed the damage wasn’t worse.  No hospital treatment for the owner on this occasion, just bruising and a dent to his pride.

The repair kit for such damage came in at a reasonable £8.99 and the eBay vendor promises to have the kit within a couple of days.  I’m sure you’ll all be waiting with baited breath to know how the repair goes.  I will of course keep you all updated.

The repair kit has arrived and there are lots of components in the box.  After watching a few (very good) YouTube videos on the S4, I think I’ll need a clear evening to repair the phone…

Cheap Tesco DVD player

This cheap and quite frankly nasty DVD player came in as a dud unit.  No lights on, nothing.  To be frank, not even I thought it would cost in to repair it, since the owner told me it didn’t cost more than £20 in the first place.

Never mind, off with the cover and a quick poke around with the multi-meter revealed no power coming from the transformer within the unit.  This converts high voltage from the mains to lower, safer voltages for the player.  On this DVD player and many others I’m sure, the internal processes are broken up in to ‘cards’.  On this unit, there’s a power card, a logic card for the motor drive and a video card for the picture.  Closer inspection of the (cheap and horrible) power card revealed several faulty components, which had failed catastrophically.  At first glance, I suspected that the cost of replacing individual components wouldn’t cost in and that sadly, this DVD player might be headed for the bin.

Fear not!  With the power of Amazon, I was able to find a generic suitable DVD power card via China that fitted, with a small amount of wiring for £5, delivered.  Job done.

Here’s a video of the fix.
