I damaged my Transmitter USB board and needed a new one.  Found one on Ebay that said it was for P3 Professional, Inspire and P4 but mine has 3 IC chips and this one has NONE.  Here is a PIC of the two.  Someone at RC-GROUPS said there were several versions of the transmitter board and the replacement board - sans ic chips - might work.  Can anyone at DJI please take a look at this photo and tell me why mine has 3 chips and replacement doesn't and if it will work?  I don't want to crash this thing.

Which is your RC model, GL300A or GL300B or GL300C? For GL300A version, you should select the PCB with 3 ICs. For GL300B or 300C model, you need the one on the right.

It's the GL300A.   And the board was the 3 chip version.  So the no chip version will not work in the transmitter at all, correct?  Because I tried it and the Go App never connected.

When you install the board (without 3 chips) on your GL300A model, it will lead to disconnection issue.

I have the same 3 IC circuit board,will an HDMI module upgrade work with mine ?

Yes it will
