Dyson DC14 with no vacuum

Another Dyson repair…

As covered a few times on my blog already, I do like Dyson products.  They’re engineer and tinker-friendly.

Fixitworkshop, March’19, Dyson DC14 (PS, I did clean the old paint off later).

A colleague got in touch with a poorly DC14 which had worked well.  She’d kept the filters clean and generally looked after the appliance with care, which makes a nice change. However, despite all this, nothing was being collected with the floor beaters.  The hose worked OK, but that was it.

Time to do some screwdriver wealding.  Despite the filters being in good condition, I washed and dried them anyway, just in case.

Up ending the vacuum cleaner revealed the problem straight away.  The bottom foot hose had become disconnected from the interference fit compression joint and was flapping in the breeze.  Usually when this happens, it’s because the hose has split, but this one was in good condition.  What seemed to have happened was that the hose had become untwisted from the joint, so all that was required was careful reassembly.

While the cleaner was in pieces, I gave it a thorough service, paying attention to all of the machine’s seals and moving parts, especially where the cylinder joins the vacuum pipes from the motor as these can leak with age.

Once spruced-up, the cleaner was back to full health once again.  Another Dyson saved from the tip.

Cost of replacement:  £150 and up.  Cost of repair: Time, tea and biscuits and silicone spray, a bit of washing-up liquid.

SEG DVB Digital TV box

It went bang, ooops!

It’s important to talk about failure as we can often learn from it and this brief write-up is all about something which left the workshop, ready for recycling.  I made it go bang, sadly.

Remember TVs before the networks ‘went digital’? They had analogue tuners built-in, which received the signals.  With so many old TVs out there, manufacturers sold digital set-top boxes, which allowed an older TV to work with the new digital TV stations from about 2007.  Since then, manufacturers include a digital receiver within their TVs of course and this particular device now seems a bit of a museum piece.

This SEG DVB Digital TV box had failed completely, so off with the lid.  Once open, the printed circuit board (PCB) was revealed.  The PCB on this device was made in two halves; one for the TV reception stuff and one for the power, the conversion of mains electricity to lower DC working voltages.  The power part of the board had some visible damage and it appeared that a smoothing capacitor had gone pop.

As it happened, I had a similar device on the shelf I was gradually stripping for spares and was able to quickly identify a suitable replacement.  Once re-soldered in and powered-up, nothing happened!

Then I spotted an on-board fuse which had also failed, but I didn’t have one of these, so I decided to temporarily short the fuse connections to make a connection.  That’s when things got smoky.

I’d missed the fact that a small transformer on the PCB had a winding short on it, which had impacted on the rest of the components.  Bang.

Never mind.  Digital boxes are still available online and that’s what I did, I ordered a new one.

Although I didn’t win this one, it’s important to have a go and that’s the whole point.  If it’s not working to begin with, what’s the worst that can happen?

Cost of repair:  A new DVB box at about £20.
