I have been working on z-5450 repair with electrolytic capacitors. I also broke off the antenna while getting the PCB out of the glue. I can't tell even where the antenna was soldered on the bottom PCB. Did you have a picture or can you describe where the antenna was attached?

Are you or the person in UK still doing repair service / cap replacement >?
Could you link to the product on Maplin site in case I decided to have a go myself

Hello. I am experiencing the flashing red light syndrom with one of my rear speakers.
I am willing to pay someone to repair the speaker for me. Let me know with a personal message,
if anyone is willing to do the repair for me.

great, I replaced the C's 100microF 16Volt , on the powersuplyboard near the cables that are connected with the amplifyer board.
Shame on logitech, that they make a product that has a life time from only 2,5 years.
Meanwhile I had this system replaced with Z906, its works well but I missed the beatifull interface with the led-screen.
perhaps I have to clame the reparation, it was not difficult but it take time to open the case.

Thanks Paradasm. The photograph and description were definitive in repairing my left speaker. Other verbal descriptions were helpful but the photo essential. I had misidentified the two capacitors so you saved me from disaster!

Thanks so much everyone. I replaced those two capacitors and red light is steady now. I have a question regarding the type of capacitor. I put in a radioshack one which seems like a generic name. I read online that low ESR capacitors are better suited to last, and brand names such as Panasonic, Nippon are better. I'm not sure whether it makes a difference for speakers that dont generate that much heat. Also, the capacitors I put in are 85 celsius instead of 105 celsius that came with the board.
So my questions are:
1. Is the radioshack capacitor sufficient? Or should I buy a brand name one with low ESR and reinstall?
2. Does the temperature rating matter for this case?
Thanks a lot.
