So-sad

Had same issue of power supply failure about 24 months out. I opened sound bar to determine if worth fixing. Here is what I found: *Power Supply appears to be good design with two heat sinks surrounding transformer. (reduces inductance interference from transformer) *Individual components looked solid. *Noticed lots of grey silicone rubber holding components in place. (There is a similar comment on another forum) This is a problem because the silicon traps heat. Over time a high percentage of the capacitors and or other components will deteriorate and fail. * If forced to speculate, this type of issue can originate from "in production" re-design. Unstable components on circuit board. (look at flow solder process.) The quick fix is to goop the components in place. Quality control should have been all over this.
