Does my (Sound bar) JBL cinema sb160 need a new power supply
THE DEVICE IS NOT LISTED
THIS IS A “JBL CINEMA SB160”
Hello thank you for looking at my post I looked everywhere on the web and couldn’t find a solution. I have two JBL soundbars and sub woofers both the same model JBL cinema sb160. One works one doesn’t!
I replaced the dead fuses in the main plug to the soundbar for both my sb and woofer this was caused by a faulty power rail that is now replaced. Sound bar does not turn on when plugged in to mains, has no lights or response to inputs. Sub woofer has a flashing light and pairs with my identical sound bar.
I tested the output of the sb power supply disconnected from the motherboard pcb. It has a 17.5V output. The plug says it is rated for 30W and 2.5A. Does this seem right or can I use a laptop charger perhaps 12V for this to work? OR is the motherboard pcb faulty and i scrap the thing.
TLDR: The plug is rated for 30W and 2.5A but the power supply reads 17.5V disconnected from the mb pcb does this seem right?
