Repairing and maintaining your sound, projector, display or AV system can be much easier than you think. As time goes by, you’ll see that systematically cables build up at your F.O.H (Front of House) position, or rodents and mechanical wear make your snake / multicore more vulnerable to al sorts of hums, buzzes and dead channels. Projectors become dirty and might experience overheating issues or simply switch off with filter warnings and displays might have ghosting images imprinted on the screens or will simply not connect to the content suppliers AP (Access Point) anymore.
In almost all cases it would be best to get us to disassemble your system that has developed issues and build it up again as new, cleaning and calibrating units as we go, removing cabling that has become obsolete and marking the once left – keeping the cables to the absolute minimum.
The image below is a good point in case. This is a sound system, driving a Bar / Restaurant Aria on the one side and a dedicated Bar Aria on the other side. This system became very problematic in that nothing seem to work reliably for more than a single event. You’ll have an event and end up fixing the radio microphone, and the following event the amplifiers go into a protected state, the next event will have speaker issues again. We proposed to open and clean most the units, repair some and replace some, six months since and not a single technical fault on a system that works daily. This is true for any AV system, faults build up over time and get “patched” to work for this or that function, but in the end – the whole thing is just one big patch, we are experts in rebuilding, repairing and re-commissioning your aged sound and display gear.
We are capable to repair, or send your unit to the specific repair centre as needed. Capable to assess and complete a repair on the brands we represent as well as some brands we do not represent. In the picture below we had to repair a Allen&Heath QU32 mixer with a frozen processor – the mixer would power up but stick to an all lights on, screen off (Allen&Heath Logo-On always) configuration. It is impossible to get around this state without replacing the processor, a hard or factory reset does not fix this, in most cases the processor (FPGA) will need to be replaced by an authorized repair centre. In southern Africa (South Africa) we can definably assist with this repair.
Sometimes a small, inexpensive unit – an audio mixer in this case – is responsible for a very large system. Here we had a customer complaining of very loud pops, randomly manifesting on the sound system. It was a Friday night and church on Sunday could not wait for a replacement unit, so we opted to open and repair the unit on site. Lucky for we could open and assess the unit.
We found that a solder point on the PC Board where the power transformer plug into became faulty over time and intermittently switched the mixer on and off in quick succession. This caused the pops and with a fresh solder job solved the problem completely.
