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

[@jmans093]

Have one of these to. It also takes it a couple of minutes for the display to fully come alive. Like the stereo though. Thanks for the video.

Glad to hear I'm not alone. Just wish that the replacement display modules weren't so expensive.

Thanks for looking into it. Saves me some time trying to fix mine.

[@litzdog911]

Hope it helps. What's wrong with yours?

[@mickrat]

Same thing. Very feint display. This is my second one. Forgot how the first one went bad but I didn’t save it and should have.

[@litzdog911]

Seems to be a common issue with that LCD display module. I wish that the replacement was cheaper.

When my unit was new, the display activated immediately. However, over time, the display takes a few minutes to turn on.

[@litzdog911]

It's clearly an issue with these displays. The unit that I got working in this video is now having the same display issue. I wish I could simply find a replacement for the display itself.

Wretched design.

[@litzdog911]

Mine worked great for nearly 15 years before the display became barely readable. It's not too hard to open up and work on, but the display is clearly a weak point. Many of the listings on eBay note that the display is defective.
