Two Polk Audio I-Sonic ES2 radios disassembly, diagnosis & repair

A tale of two Polk Audio I-Sonic ES2 radios. I originally set out to attempt to repair the display on my original 15-year-old radio. It lacks contrast and is barely readable, which seems to be a common issue with these units. There is not much information about these units on the web or YouTube, so hopefully this video will be useful for others attempting to diagnose or repair theirs. The first part of this video documents the disassembly and diagnosis of the display issue. Sadly, it seems that the problem is the display module itself. Replacing those display modules would cost more than these radios are now worth. The displays on eBay currently seem to fetch ~$150 while you can buy a working i-Sonic ES2 for under $100. Of course, if anyone viewing this video has any ideas on how to possibly repair this display, please let me know. The second part of this video describes replacing a couple of the amplifier capacitors in a second i-Sonic ES2 that I purchased on eBay for $70. It was sold for "parts only" without a power supply. Fortunately, its display works, at least sort of. But I discovered a couple of leaking capacitors and replaced those. If anyone is interested in my now "parts only" unit with the weak display, just let me know. I'll probably be listing on eBay at some point.
