Imalent DN70 driver fix

I got a malfunctioning DN70 from a friend to fix.
He don't know what happen but it stopped lightning (the screen is still functioning)

After a lot of trouble I manged to take out the Driver (It is glued, great engineering Imalent) and the boost converter is fried (and possibly some other components).
It is 20 pins VQFN so I doubt if I can replace it.
Where can I buy a new compatible driver?

I have contacted Imalent and they send me a new driver for 20 USD.
Great costumer service but not so great engineering, since the driver was glued to the body, I had to drill it out.

Now I had a new driver but still had to fix the body....
This Russian guy used a CNC machine to do it but I don't have one so I used a Dremel, 2 coins and heat sink glue to do it Smile

Could you explain how did you take off the drive? How did you unglue and pull it out?
My DN70 is not charging because of a problem with USB port and I need to replace it.

Thanks in advance

As far as I remember, I removed the MPCB with LED and drilled the plate behind it and then pushed the driver out using a thin tool trying not to damage the driver.
Try to disconnect all wires/ribbons you can before doing it

I recommend contacting the company before you do it since I think they told me they no longer have spare parts for this model
