Technical Service Bulletin - SkyView Display Circuit Board Replacement - Revision B

Date: March 4, 2013
Revised March 26, 2014



Note that this is Revision B of this service bulletin. Revision B supersedes and replaces an earlier version of this bulletin that was released on Feb. 11, 2013.

The original bulletin specified a SkyView-based on-screen detection method to determine whether or not a display was affected. However, displays that were thought to be unaffected based on the on-screen detection method may actually be affected by this bulletin.

Therefore, ALL SkyView displays, whether or not they were already checked against the original service bulletin on this topic, must be re-checked using the updated instructions in this document.

An investigation revealed a manufacturing process deviation at a subcontractor which can cause a weakness in a printed circuit board that fulfills a critical role in a SkyView Display. Over time, this weakness can turn into a defect and manifest itself in behavior including a display that does not power on; a display that powers on, but does not fully boot; or one that freezes during operation. Affected displays should be returned for repair.

This Technical Service Bulletin instructs customers on how to determine if their equipment is affected. Returned displays will have the affected circuit board replaced. All other hardware will be updated as necessary and the display will be tested to ensure factory-new functionality.

Applicability and Affected Equipment

Only SV-D700 and SV-D1000 displays that contain a certain printed circuit board are affected and should be returned to Dynon for repair.

The displays that have the suspect circuit board shipped from approximately mid-2010 to mid-2011; however, these dates are not authoritative.

If you have an SV-D1000 whose serial number is 6000 or greater, this bulletin does not apply to that display and it is not affected. No further action is required.

If you have an SV-D700 whose serial number is 4000 or greater, this bulletin does not apply to that display and it is not affected. No further action is required.

If you have an SV-D1000 with a serial number under 6000 or an SV-D700 with a serial number under 4000: SkyView displays have the ability to report a hardware MAC Address identifier that can be used to determine whether a display is affected once it is loaded with version 5.1 firmware or greater. This is the only accurate method to determine whether your display is affected. Neither serial number nor ship date alone can determine whether or not a display is affected. Your display MUST be upgraded to 5.1 or greater to be able to see the MAC Address.

Use the following process to load the lastest firmware and determine whether or not your display(s) are affected by this bulletin:

  1. Turn on the SkyView Display and load the latest available SkyView system software per the instructions in Section 3 of the SkyView Installation Guide.
  2. Open the SETUP MENU by pressing and holding buttons seven and eight.
  3. Open the LOCAL DISPLAY SETUP page.
  5. The MAC ADDRESS is displayed under the serial number and firmware version as shown in Figure 1 below.
  6. It takes approximately 1 minute for SkyView to report a non-zero MAC Address. If the MAC address is all zeroes, wait until it changes to a value that contains numbers and letters as seen below.
  7. Write down the MAC Address and serial number.
  8. Go to the following link to check whether your display is affected: SkyView Bulletin Check

Method of Compliance

The web tool at SkyView Bulletin Check is the only way to determine whether your display is affected. AFTER you have used this tool to determine that your display is affected:

  1. If the tool determines that your display is affected, you will be prompted to fill out a form that allows you to request an RMA (return materials authorization).
  2. If you have more than one SkyView display, use SkyView Bulletin Check to check each display individually, or, call us at (425) 402-0433. You will be asked to provide display type(s) (i.e., SV-D700 or SV-D1000), serial number(s), MAC Address, your name, your email address, your phone number, and your shipping address.
  3. If you do not have the original shipping box with insert, Dynon will send you a box with a prepaid return address label. If you do have the original shipping box with insert, Dynon will email a prepaid return address label. You need to specify this information while initiating the RMA process.
  4. Dynon will email you an RMA number and shipping instructions.
  5. Ship the product to Dynon.

You may also contact technical support by phone at (425) 402-0433 or email at Please be ready to provide display type(s) (i.e., SV-D700 or SV-D1000), serial number(s), MAC Address for each display, your name, your email address, your phone number, your shipping address, and if you need a shipping box or not.

The repair process at our facility takes approximately 10 business days. The repaired display will be returned with the firmware version you were running and all of your settings and licenses intact.

Time in Effect

This technical service bulletin is in effect indefinitely.

Dynon Avionics recommends that you arrange for repair of your affected display(s) as soon as practical.

Although complying with this bulletin is very highly recommended, it is not mandatory. Non-compliance with this bulletin need not necessarily ground your aircraft.

Notice to Special Light Sport Aircraft (S-LSA) and Other Non-experimental Customers

You are solely responsible for ensuring that your aircraft is airworthy. In the case of S-LSA aircraft, owners may need special authorization to remove, replace, or update the firmware on a SkyView display(s) if such operations are not permitted in the maintenance manual. Please refer to your aircraft maintenance manual or contact your aircraft manufacturer concerning removing, replacing or updating firmware on your SkyView display(s).
