The Blackmagic Design Spares - ATEM Television Studio Pro HD - Main PCB is the primary processing motherboard for the all-in-one live production switcher. While the chassis houses several smaller boards for the buttons, fader, and audio I/O, the Main PCB is the central "hub" where all video switching, FPGA-based effects, and system logic reside.

Because the Television Studio Pro HD is a fan-cooled, high-density unit, the Main PCB is designed to handle simultaneous 1080p60 processing across 8 inputs while managing the internal hardware control panel.


Core Responsibilities

  • Video Cross-Point: Manages the physical switching between the 4 SDI and 4 HDMI inputs.

  • FPGA Processing: Drives the DVE (Digital Video Effects) engine, upstream chroma keyers, and two downstream keyers.

  • Resync & Scaling: Each input on this board features a dedicated frame re-synchronizer, allowing you to mix consumer cameras and professional broadcast sources without external genlock.

  • Multiview Generation: Processes the 8-input + Program + Preview layout for the HDMI and SDI Multiview outputs.

  • Flash Memory: Houses the non-volatile memory for the Media Pool, allowing the switcher to retain 20 RGBA graphics even after power-off.


When to Replace the Main PCB

  • Total Signal Blackout: The console powers on and the buttons light up, but there is no video output from Program, Preview, or Multiview.

  • Input "Death": Specific inputs (e.g., all 4 HDMI ports or all 4 SDI ports) stop functioning simultaneously while others work, indicating a failure in the input controller bank on the Main PCB.

  • Fan/Thermal Error: If the onboard thermal sensors fail, the switcher may refuse to boot or enter a permanent "emergency shutdown" loop.

  • Sync Issues: Frequent "glitching" or frame-tearing across all inputs that isn't resolved by firmware updates usually points to a failing clock crystal or FPGA on the motherboard.

  • Network Connectivity Failure: If the Ethernet port is physically fine but the ATEM Software Control cannot "see" the unit even after a factory reset, the network controller on the PCB has likely failed.


Technical Installation Note

Repair Level: 4 (Advanced). This is a significant mechanical undertaking.

  1. Bottom-Entry Access: You must flip the console and remove a large number of screws (roughly 20-30) to remove the bottom metal plate.

  2. Ribbon Cable Forest: The Main PCB is connected to the Button Panel PCB, the Audio I/O Board, and the T-Bar assembly via numerous delicate ribbon cables. You must map these carefully before disconnection.

  3. The Cooling System: The Main PCB is cooled by an internal fan and a copper heatsink. When swapping the board, you must ensure the heatsink is properly seated and fresh thermal paste or pads are applied to the central processing chips.

  4. Internal Power Supply: The $110\text{V}$$240\text{V}$ IEC power supply module is located near the Main PCB. DANGER: Ensure the unit has been unplugged for at least 15 minutes before touching internal components to allow the capacitors to discharge.


Diagnostic Tip: Firmware Recovery

Before assuming the Main PCB is dead, attempt a Recovery Mode update:

  1. Connect the ATEM to a computer via USB.

  2. Hold down the Set button (or Inquiry on some versions) while powering on the unit.

  3. The ATEM Setup Utility on your computer should prompt you to "Recover" or "Update" the firmware. If this fails to register the device, the Main PCB logic is almost certainly compromised.

Expert Advice: If your issue is only related to the physical buttons not responding, you likely need the Control Panel PCB, not the Main PCB. The Main PCB is only the culprit if the electronic "brain" of the switcher is failing to process video or communicate with the software.

Are you losing video signal entirely, or is the console simply failing to connect to your computer?

A great printer with lower pricing
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I am quite happy with my ET-4800 purchase. From wirelessly connecting to my Mac to software installation to adding the ink, it was easy to set up. I feel you can't go wrong with this level of ink capacity. It holds so much ink without the bother and added expense of frequently replacing cartridges. I will never go back to a cartridge machine. I don't care who makes it! I've used my printer several times so far, and each time it has done a great job by giving me the colors and clarity that I expected. This is the first printer that I've owned that wasn't a front-feeder. I wasn't sure how I would like that, but I've found that holding the paper straight and then dropping it into the slot rather than placing it, gives the best result for paper alignment. For my needs, I have only used it one sheet of paper at a time. So if you are wanting to load several sheets at once, your loading experience may be different from mine. But just make sure that you do not load more than 100 sheets at a time, per the manufacturer's instructions. Also, be sure that the movable paper guides are in the correct spots for the size of paper being used, without any buckling. To date, I have not used the scanner, but it is definitely a feature that I did not want to be without, so I'm looking forward to using it. The display window, though small, is simple to follow along with, and I appreciate that the angle of the keypad can be adjusted. Working with the Epson Smart Panel app gives a bit more flexibility, particularly if you're not right next to your printer and want to check the ink levels or start a printing job. To use the app, be sure that you turn on your printer first and that both the printer and your device are set to the same wi-fi, so that the app can find your printer and you can begin operating it from afar. Once inside of the app, be sure to check out the "Other Features Menu" from the app's homescreen. There is a link to another Epson app that can be used to boost your creativity and streamline layouts for collages, and a colorful guide full of project ideas that outline everything that you need for each project and how to execute them. There's even a feature for sharing what you've scanned and submitting it as an assignment. This is something that you'd want to read more about to see if it is an applicable and helpful addition for you. You can use the search term, "google classroom in epson smart panel app," to find out more. There is only one downside that I have found at this point. The pull-out paper catching tray in the front feels flimsy. It seems out of place on an otherwise sturdy machine. But so far, I've had no problems with it. I just take my time pulling it out, flipping down the end, folding it back up, and pushing the tray back in. I figure if I baby it a bit, then all should be well. Overall, I really like the Epson ET-4800 as much as my ET-5170. I feel it performs well at an acceptable price point.

Excellent product for the price.
Style: ET-4800, Color: White, Set: FAX/ADF/Print/Copy/Scan
I have had many, many printers over the many years at the business and for home. I honestly think this is the best value for what I need. The eco tank is fabulous. This is the first printer I have purchased with the ecotank. So much better than the cartridges. The quality is good and it was easy to setup and put on the network. I did wait a few months before writing this review to truly test it out and write a fair review. I am pleased. I have had Epson products in the past and do appreciate their quality and affordability.
