Barco OL-721 videowall rehabilitation

Control Room and AV Solutions was tasked with rehabilitating a 74 cube Barco LED lit OL-721 videowall in Gauteng, South Africa.

Repairs and rehabilitation involved PCB level repairs to blown power supplies, image alignment, colour balance and software configuration. Also configured was a second LCD display in a different room.

  • Covers removed to assess the dead cubes.

Cost effective boardroom AV

A functional and effective boardroom audio visual installation need not cost a small fortune.

We were tasked with providing a cost effective solution in two boardrooms at a local beverage supplier. The client wanted a simple, wired solution capable of showing presentations from laptops and utilising both VGA and HDMI cables. Nothing more! So, that is exactly what we provided.

Barco videowall relocation

We received a rather unusual request in October 2018: Relocate a 10 year old 30 cube Barco videowall and Transform A computer system from an existing site to a new location in Johannesburg, South Africa!

This request, no doubt, came with a unique set of challenges and risks. Given that this equipment was long since declared “end of life” by Barco and no spare parts or support was available from Belgium for this “relic” the biggest risk in taking on this mammoth project was damage resulting from dismantling and transporting the equipment.

Personally for me, the bigger the challenge, the bigger the feeling of satisfaction, so I applied my mind to the challenge and accepted the project from this client.

Needless to say, we were able to successfully pull off this “miracle” and I got to experience my satisfaction!

Our team was all too aware of just how careful we had to be. I knew that the equipment would be in good hands. After all, I had personally, in the past, overseen the installation of many of these old Barco videowalls and was quite familiar with the Windows XP based Apollo software and Transform A computer system, and I had a competent team.

Control Room and AV Solutions, in conjunction with Peripheral Vision, the South African distributor of Barco, installed a complete Barco solution at the Telesom control room in Hargeisa, Somaliland.

34 Barco IVD5521 narrow bezel LCD panels were installed in a curved configuration for the main videowall which is driven by multiple Barco linux output nodes. This combination allows for the entire display to function as one large logical screen.

The content management was achieved with the Barco CMS (Control Room Management Suite) software package, especially developed for control room applications.

The entire project, from assembly to commissioning, was concluded in just over a week!

Barco videowall upgrade at the CSIR

Control Room and AV Solutions recently performed some recommended routine maintenance to the large 15 cube Barco videowall at the CSIR in Pretoria, South Africa.

The replacement of the LED light source and cooling units is recommended after five years of operation on the OL series Barco videowalls.

New generation-3 LED chains and cooling units

The new generation-3 LED chains which were installed represents the latest in LED chain technology, and is considered to be an upgrade from the original generation-2 devices originally supplied with the videowall.

In addition, all fifteen cubes had their liquid cooling units replaced to allow for optimum cooling of the redundant LEDs and internal electronics.

  • Initial alignment check
Image alignment and colour balance

Once all the LED chains and cooling units were replaced, an image alignment and colour balance was performed to ensure that any content displayed over the entire 15 screens appeared uniform.

The entire operation was completed within three days.

• 25% less power consumption at higher brightness levels
• More than 11 years of uninterrupted operation in 24/7 mode
• Unmatched colors, focus, and contrast levels
• Silent like never before (‘library’ noise level)
• Redundancy of critical components for ultimate peace of mind
• 50% setup-time reduction (motorized 7-axis alignment)

This 2×2 configuration videowall took our team less than two days to set up, from scratch, including the cladding, alignment and color balance.
