Wismec Reuleaux RX200S Blank Screen Fix

A reader sent his RX200S, after reading the rx2/3 fix, hoping I could fix a blank screen issue.

Hooked up to PC where the firmware tool successfully detected the device. Went ahead and updated the firmware to V4.13. This let me know there wasn’t a processor issue.

I disassembled and checked connections. The ribbon cable seemed loose.

Used a heat gun to reflow the ribbon solderings. Got info on the display but it was very dim. The issue still persisted but the ribbon cable definitely needed this because it was separating from the solder.

After poking around at the surface mounted resistors near the ribbon traces I found that bridging two of the resistors the screen came to life. My untested assumption is that one of the resistors went bad and bridging them brought the screen back to life.

Reassembled and tested again. The resistance of the coil reads the same on 2 devices and the wattage to run the coil is equal between the 2 devices. Good to go.

Try this at you’re own risk and understand I’m not responsible for anything that goes wrong.

With no drops, no overheating, 2 batteries in use and a lower power user the Wismec rX2/3 started throwing a Check Battery error. I did not have the proper hex bit to do the existing standard fixes so I came up with a new fix.

To test if this is the fix for you connect a piece of wire to the 2 points below with batteries in and attempt to fire the device. If the Check Battery error does not appear then this fix should work for you.

The new fix bypasses the cover connections. With that said the note that this fix has not been checked against using 3 batteries so use at your own risk. I apologize for not taking pictures during the repair so I have illustrated over pictures posted on the net by others. Credit for original images at end of post.

Solder a wire between the 2 points circled in yellow and shown connected in red. Beauty of this fix is that you can test without the back cover. Once the new wire was is in place I reassembled with everything working.

If you use this fix contact me and let me know how it turned out.
