DJI has not solved the heat problem and the circuit board reflow is cummlative, you use the CS UB on full brightness it heats up and the solder reflow happens, the next time you use it, the more reflow and eventually the circuit is broken as the solder has melted and the blacklight fails.
It's just a poor design, that never did any field testing in real flying conditions in real user scenario's, you'll notice that it's not available on the website anymore, it's showing as out of stock as DJI cannot fix the design.
Thanks for the explanation and with that going on, I can see more going wrong on the circuit board too if it becomes polluted with the solder.
You think they could come up with a fix with some type of insulating adhesive or coating that could withstand the heat and encapsulate the problem area.
I have a 7.85 Ultra-Bright that I purchased around the second week of February. I have yet to open it and it is still factory sealed. The reason being, I became real paranoid after receiving it then reading these horror stories........lol
So, yesterday, I opened a case and asked if I could send it back to exchange for a high brightness. Today, I got an email back saying I could not have a refund due to the 14 day grace period having passed. So, I had to reply and say I did not want a refund but to exchange for a standard unit. I also asked if they could not do anything for me, to pass it on to a supervisor who may look into this further for me and stated about the numerous failures being received by DJI repair.
But, if they insist that I keep this one and go through the channels if it fails, they will not get it back. I will take it to one of these electronic repair places that works on cell phones, computers, etc. In fact, here is a gentleman who is also an expert dji repair person who could probably diagnose and repair the problem properly. www.irepairmd.com
It would probably be worth paying out of pocket instead of going through the stress and anxiety of the repair gauntlet. |
