Question about Bose Lifestyle 30 System
Older Bose Lifestyle systems are prone to electrolytic capacitor failures. Replace all electrolytic capacitors on the main control board with identical uF value, equal or greater voltage rating, equal or greater temp rating. There are about a dozen on the board with at 2-3 different values. Disassembly and reassembly is straight forward. Those with capable skills in mechanical and electrical areas should find the project will take about 1-2 hours. I recommend grounding the board when working on it. Find a spot on the board where the ground is marked, and attach a jumper to a ground point. Take caution during the disassembly -- take photos, lots of plastic parts, etc. The eCaps are polarized, so be sure to check polarity as you unsolder, and install new eCaps with same polarity (+ & - ) as the old.
Once caps are replaced the voltage levels to correctly operate the display will be back to factory settings, and the display should show brightly. Good Luck!
