I recently used a BW-70KIT to repair a Sony RMF-TX310U TV remote for a
Sony X900F Series flat panel TV.
I had already used the ButtonWorx product before to repair an alarm
panel, so I knew it worked.
Photo 1 shows the remote with the back battery cover removed.
Photo 2 shows a comparison of the rubber membrane and the circuit
board. I don't normally use all of the buttons on the remote, so I
wanted to see which button circuit traces I wouldn't need. This photo
shows the membrane and circuit board after they were cleaned with 90%
isopropyl alcohol. When I got the remote apart for this repair, the
membrane contacts and the circuit traces were filthy with some sort of
oil and other gook. I had cleaned this remote about 2 years earlier
before I had heard of the ButtonWorx product. The cleaning restored
operation temporarily, but cleaning repairs only work for a limited time
and will eventually destroy the conductive material on the membrane
buttons. It's also very difficult to get this remote apart. A very
small screwdriver or razor blade must be slid down the side of the
remote so the tabs can be released. Time for a permanent repair with
ButtonWorx.
Photo 3 shows the completed repair. I ended up covering virtually all
of the button circuit traces. I had purchased two of the BW-70KIT
packages to ensure I would have enough buttons for the repair. It's
possible to fix this remote with only one BW-70KIT. Virtually all of
the buttons in the kit are used in the repair, so do not purchase a
smaller kit.
I guess this remote is used with a lot of Sony TVs from the 2019 time
frame. I considered scanning the circuit board so we could work
together to develop a unitized keypad. Unfortunately, we did not have
another remote which could control the TV, and the wife watches a lot of
TV. Perhaps best to forego the new product development and just keep
the wife happy.
So far, all the buttons are back to working order!
Thanks for a great product!
