Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Right there in your receipt is a "Contact this store" link... Did you try asking Hcxqsgroup there, they are the manufacturer/seller? I'd think that'd be the starting point.... Just sayin'...

I have not got any place to buy a new display. Now I have taken some pictures for helping identifying my display. It have a marking HSD-6767J-D3, if it can help

I think, You already got the ansfer from Vladimir...

You need to remove from the interface board... and reuse with the new display...

Sadly, it’s not the right one. I’m attaching two pictures: the original one (wide connector soldered to the PCB) and the AliExpress one (narrow connector).

I’m still looking for a true 1:1 replacement, could anybody help me out?

Hello !
Display driver ST7796S or ILI9486? Please ask by developer team - 48 pin for soldering on a pcb
NanoVNA-H4 and SAA-2N have a 4" (3.95") display with 40 pin connector to plug in.
