Please help me on my GW-9200J which I got from goodwill.
I got it with nothing on display (blank screen). I thought it's just a battery change.
But when I change the battery (CTL1616 from Pacparts) and AC reset, some part of the digits on the LCD are missing.
All functions are OK including auto/manual sync.
Picture below.

And how can I remove the cable here?

I saw some Kung's post before regarding MODs on Riseman, but the pictures are all gone.

2 possibilities"

- module not tight enough, try to tighten some screws to see if the missing parts of digits come up

- dead pixel ?

be careful when/if you take out the module, the red you circled the the latch that keep the sensor wire, I broke one of mine

Yes most, if not all of Kung Fusions pictures are now gone since he closed an account that had them stored. His departure from the forum is sad but understandable. I personally have not opened a solar connections like that. I was lucky that the solar watches I have taken apart were connected with springs just touching the solar panel. Those modules just lifted out with no issues.

How do i work on the latch? Is there a way to open it? Did you figure it out how to remove and reconnect it?
I want to remove the module but that's my first problem.
The second is the connection to the solar panel.
If it's a dead pixel, what part should be replaced? Is it the LCD?

like every solar module, there are two springs from the module touching out to the solar panel, so just lift out the module after you remove the sensor-wire
most of the time the springs won't drop out, but you need to pay attention to it just in case



as for how to fix the pixel, I have no ideas, i have had 2 or 3 Gshocks with missing of digits myself, ending getting used G to get the module from there, as I realize that I am not skillful enough to open up a module

Not the point of this thread, but I didn't understand why Kung deleted the image account for the mods. It was a treasure trove of information. I hope others think twice before nuking their images.

The missing pixel could be due to the soft conductor piece touching connecting the lcd and the board not align or contacting properly. Make sure the module is closed up tightly.

Thanks for the tip, I finally removed the module but I will disassemble it later. I will try my luck with this module, it's my first time actually to disassemble a module like this. I noticed the digits with this module are still readable even if it is very inclined, about 20-40 degrees. Other module, it will appear some shadows of the digits if you look at it in a certain angle.

I am hoping it's just a misalignment problem or the most is LCD replacement. But getting to that will be my next challenge.
