This repair fixes:

• An E1 or E3 error on your flash
• Your flash powers up but will not fire, and the flash tube is fine.

If your AD300Pro is showing an E1 or E3 error it requires the replacement of the main drive board. This repair also covers if your AD300Pro powers up normally but will not fire. This is an issue with a component on the capacitor board.

Please place your order and complete and ship your flash to us at the address listed below. Just ship the flash body to us; we don't need the heads or battery. Include a printout of your order confirmation that you will receive via email.

How to order:

1. Copy this shipping address down. This is where to ship your flash:
   • MoLight Repair, 707 W Lexington Pkwy, DeForest, WI  53532
2. Add the repair to your shopping cart and then checkout and pay for the repair. This will put your repair into our queue.
3. Once you have paid you will receive an email with your six-digit order confirmation number. Print that out and include it in the box with your flash.
4. Ship your flash to us. We just need the main body of the flash; no heads, no battery. Wrap it in bubble wrap or safely cushion the flash unit. We are not responsible for any damage that occurs to the flash on its way to us, so make sure that it is well protected. Ship it using a service with tracking, like UPS Ground, FedEx Ground, or USPS Priority Mail. Please note that it will typically take 2-4 business days to arrive to us once you have shipped it. If you are concerned about if it arrived, use your tracking number to check.
5. Please allow 2-3 weeks for us to complete your repair after it arrives. We try to be efficient as possible because of the high volume of repairs we receive. Once we start your repair, we complete your repair. If we encounter any issues, we will contact you. Otherwise, we do not reach out to you unnecessarily during the repair process. We keep our heads down and finish the repair, then ship it out the next business day after completion.
6. We ask that you please avoid phone calls and emails asking us if we got the flash, or how the repair is going. That's our #1 source of calls, and it pulls time away from actually getting the repairs done. It is our goal to get your repair done as soon as possible and move onto the next repair.

Just ship the flash body itself without battery or accessories. If you choose to the leave the bulb in please attach the reflector with the bulb cover. We are not responsible for any damage to the bulb or glass bulb dome while shipping. Because of this you may want to remove the bulb prior to shipping. You may send the flash back in its original case, or wrap the flash in bubble wrap for protection.

The shipment charge for your order covers the return shipping from MoLight to you. You still will need to cover the shipping cost for shipping the flash to Molight.
