Electronics Repairs Humpty Doo

TVs, amplifiers, appliance boards, inverters, chargers and controllers from Humpty Doo, repaired at the component level in our Winnellie workshop.

We design and make circuit boards, so we have the gear to find the one part that failed instead of replacing the whole thing. Free diagnosis and a written quote before any work.

Humpty Doo is rural — hobby farms, large sheds, water and bore systems, off-grid and partial-grid setups, and a fair number of small businesses run from home blocks. Repair work out here tends to be infrastructure: pumps, gates, controllers, inverters, and comms gear that has to keep running through the wet.

What we fix

What we fix for Humpty Doo.

TVs, audio and home electronics

No power, no picture, no sound. Power boards, backlights and amplifiers repaired. Cracked panels are rarely worth it, and we say so.

Appliance control boards

Washing machine, dishwasher, oven and air-conditioner boards, often the only failed part on an appliance that’s otherwise fine.

Inverters, chargers and power supplies

Solar and 12V inverters, battery chargers, UPS units and power supplies, including storm and surge damage.

Controllers and industrial boards

Control boards, drives and PLCs from pumps, gates, sheds and workshops, plus replacement boards designed here when the original is obsolete.

How it works

Drop it in. We look. You decide.

01

Bring it in

4/143 Coonawarra Rd, Winnellie, Monday to Friday 9am to 5pm, with any power supply or remote. Bolted-down gear can be seen on site.

02

Free diagnosis

We test it, find the failed part and give you a written quote.

03

Repair and test

If it’s worth doing, we do it and test it before it leaves. If it isn’t, you pay nothing for the look.

Coverage

Workshop drop-off, or on site when it makes sense.

Humpty Doo is around a 40-minute run from our Winnellie workshop via the Arnhem Highway. Rural callouts get scheduled in blocks to share travel time across multiple jobs.

About 35 km from our Winnellie workshop. Drop-off is the fastest path for repairs; on-site visits are quoted up front.
