Can anyone confirm the value of L2 as 3.3uH ?
In my hurry to replace the offending capacitors, I shoved the adjacent resistor out of the way to make room, only to discover it's actually a far more delicate inductor. Snap!
Can anyone confirm: orange, orange, gold, silver? (3.3uH)
I make it 3.3uH but the colours are difficult to read. Looks like it has been running hot. It might be red, brown?

so, i followed the advice of excellently helpful thread, replaced the capacitors, and immediately the blue light started blinking.
in fixing it though, i accidentally tore the antenna off, and despite resoldering it seemingly in place, now having weird data loss problems. the capacitor issue seems absolutely fixed, but the speaker can't maintain a signal now. even more weirdly, it cuts off immediately when i turn the back left speaker on, as if they can't both be on at the same time without a conflict. i'll make a separate thread for this too, but just wondering if you clever folk have any advice in the meantime. thanks!

Problem with flashing red light fixed on both speakers. Replacing capacitors worked like gold. Mind that mine didnt even looked like demaged ones.
Big THANKS from Poland

How do you know that it is TDA8922BTH? Have you got a schematic diagram? I need one badly. Cause my Z-5450 turns off always after 10-15 sec. I can fix it on my own but I need a diagram or service manual.

THANK YOU for the how to! My rear left speaker started flashing the dreaded blinking red LED of death a few months ago and I thought it was toast. I did a quick google search for the issue and came across this forum. I replaced the two 10v capacitors with 100uF 35v ones and it did the trick! I was beyond THRILLED to see my solid blue light again upon powering it up! THANK YOU again!
On a side note: what a freaking pain it was to open the speaker! So much glue! WOW! You need a TON of patience to get that bad boy apart! Also, I had absolutely ZERO experience with soldering to a PCB so I also did a how to search on google for that as well! After some trial and error I was confident enough to have a go on the unit and got it on the 1st try! BOOM! My Z-5450's are still in tip top shape after 7 years! Good thing, too since they're no longer in production! If I come across another blinking red LED, I'll know what to do! MAJOR PROPS, hamishi........2.5 years after you posted that fix people are still benefiting!

I have the same problem with my left rear speaker.
Is here somebody who can sell me this wireless speaker ? We can manage the payment by PayPal.
Thank you very much for your help

Jedla, you should consider having a go fixing it yourself because I'm not sure you'll have much luck finding this exact speaker as a replacement. You'll be surprised what 2 little capacitors can do! Hamishi provided all the info you'll need to know and there's also a picture a few pages earlier of the exact ones to replace. Good luck!
