I purchased NeoPixel 1/4 60 Ring but only the first board of led is working, the other 3 board is not working. But when I test them individually all 4 board is okay.
I used RGBWstrandtest from the library. Power supply and soldering joints are okay too.
I connect 3 DIN-DOUT, Left one DIN-DOUT Open. This DIN pin is connected to Arduino D6
To rule out the obvious you did increase the NUMPIXELS to 60 in your code? Other than that with all sections testing good, it has to be a connection issue. Maybe re-flow all the solder joints. Test all the segment connections for continuity. Make sure the broken signal connection foil pads are not touching.

Yes, I changed to 60. Soldered and desoldered the connection a couple of times, Individually every board is working.

Yes, This is my starting point. I left it disconnected. I connect L shaped pin-header in DIN from which I use a jumper wire to Arduino.
Your other photo of your segment-to-segment solder connection looks OK. Is that the current state of the solder connection at the first segment junction?
Also, post your complete code. Let's double check it's not something simple like the number of pixels, even though you mention changing that.
