Introduction

Over time, the touch buttons on the SRS-X7 may stop functioning. Double-sided tape used during manufacturing is the cause of the problem - probably as a result of degradation of the glue causing a change in capacitance.

Rather than paying a Sony service department to look at your speaker, repair it yourself economically.

Unfortunately the manufacturer chose not to issue a recall over this problem.

  • ** IMPORTANT ** Wear safety glasses for this step. Whenever prying with a knife, I recommend wearing safety glasses. If the blade breaks, shrapnel could fly into your eye causing damage or blindness.

  • Use an xacto-knife or pocket knife sharpened to a 15 degree angle.

  • Twist the knife blade in order to lift up the cover.

  • Do not scratch the bezel or cover, and try to avoid scratching the painted surface under the cover.

Image 1/1: Silicone sealant works well.
  • Put very small amounts of adhesive at the points identified with little squares of masking tape. Don't add the little squares of masking tape!

  • Silicone sealant works well.

  • Avoid putting adhesive over the areas directly above the touch pads or the grey light spreader on the upper-left.

  • Best to apply adhesive to the chassis, rather than the cover.

  • Keep in mind, adhesive spreads a lot, so little means VERY LITTLE.

Conclusion

Your speaker should now be re-assembled and ready to rock.

This was my first ifixit contribution. I hope you like it and find it useful. These speakers sound great when they work. It's a shame Sony chose to hasten the manufacturing process by use of large pads of double-sided tape. If they had gone with a liquid adhesive, or used die-cut double-sided tape that didn't cover the sensors, they could have saved a lot of headache for their customers.

I am always fixing brand-new-out-of-the-box products, and fixing products that failed far too soon. It never ceases to amaze me how manufacturers cut corners, and pass the resulting problems on to their customers. That's why I believe trust has been eroded between the consumer and the manufacturer.
