Hi, I have a Lifestyle 20 with a very dim display, I have read where you can change a capacitor C19, but not sure if I have the same model? C19, 18, 17 and 16 are all very small surface mount devices, is this correct?
I don't seem to be able to find a 63V 100uF SMT in the same config?
There are five 100uf 50v through hole caps on the power supply pcb. You might as well replace ALL of the electrolytic caps on the board since Bose used cheap 85C caps instead of quality 105C ones. Install some Panasonic FC caps of the appropriate values from Digikey and your display should come back to life.

Change capacitor C19 (33uF 63v) next to the dispaly. This capacitor goes leaky over time, and causes ripple on the display which makes it dim or even dissapear completley. Also worth doing all the capacitors near to C19 while your there just in case.
changing C19 worked for me. Some people even up rate the capacitor to 100v, but 63v id the manufacturers reccomended.
Displays die quite often on receivers just one of those things that happens.
Bose is pretty good about repair cost and timely in their turnaround. Here is a link to the support page
I would guess a replacement display would run about $150 installed plus you will have to ship your unit to them.
They like to do "flat rate" service plans which is one of those 50/50 deals most of the time you are better off just paying for the repair versus dealing with a service contract but you will have to find out whats available for your model.
Its working lifestyle 5, 8, 10, 12 receivers Its Easy fix you need
open it up and on lover left corner on bottom first capacitor value
3.3uF needs to be replaced.I did all ready 3 units and its all work now
Hi the fix for a dead display is a faulty capacitor. Depending upon which board version you have, you need to replace the 33 uF / 63 volt capaitor. On some units this is C19 on the display board, on other units this capacitor is mounted on the main board and re-numbered, there is only one 33 uF on the unit so you should be able to find it. Dave
My display has not been working for years. Replaced c17 cap wich was 33uF 63 volts on lower pcb board( only one on system) . Old cap was good so this was not the problem. Replaced c16 wich was 100uF 25 volts with a 100uF 63volts. Display works, old cap read low. Both c17, and c16 are located on the lower left hand corner of the larger pcb looking from the front of the unit. Hope this helps.
