I really like the Bangggod site (goo.gl/zFf835) for various reasons: ships worldwide, great prices, no extra shipping cost and no minimum order !!!

Very helpful video, mine PSU in Z313 stopped working 3 months after warranty end. Got similar PSU to your and now speakers are working. :)
Thanks!
What psu did u buy please answer i have same issue
dude that was awesome nice fix
Hi ! Solved my problem thanks to you ! After seeing your video i bought a power supply in Bangood and replaced it like you did. It works really nice ! Thanks :)
Hola amigo a esta plca se le puede poner una fuente de 16 vol gracias espero me responda
Thank you for this excellent video!
what if the channel balance is off?, where can i get that potentiometer (7 pole)
Thanks matey, almost 6 years after posting, this is still relevant, as Logitech is still using that dodgy PS. Works like a treat now. Was wondering why you did put the voltage to it's maximum, instead of leaving it at 12V ?
My psu also burned out thanks for the reference
It seems you solved my problem ...Thanks...
I have Z323 with same problem but the diode is SR3100. I take out the dead diode and it is working with one diode. :)
Hi RideLifeWithGrace, I have a Logitech Z533 that burned out the power supply. Since I don't know which (TPA) audio amplifier is installed on this Z533 system, I don't know what power supply and what DC voltage I should use to replace the original. Thank you for your help as I have the Z533 system out of action for a long time and after watching your video I was hoping to be able to use it again...
Forgive my English, it's not my native language.
La salida de esa fuente de alimentación, la original son 12v, 4 A, es también corriente alterna (AC), si la cambio por una de corriente continua (CC), ¿Funcionará?
no note work
I tried it on a dc charger and the( TDA) sound ic blew out.
can u help me i have same issue what PSu should i buy and can you teach me how to put it on?
can you help me ? i forget to turn it off for 2 days..then when i wanna use it suddenly i realize i forgot to turn it off..now its dead..i think the problem is the psu..
How do you fix grounding? Mine bont have grounding line and I connected woithout. Now I have buzing noise and I believe it is because of grounding.
i have same problem
Do u solve it?
I have Logitech z333 its smps blown can I put a new SMPS ? It's writen 94v-0 E317641 ZR-01 I want to know IS ITS 94VOLT psu OR 12 VOLT ?
After a quick research, the Z333 speakers have the same STA540 power amplifier. According to the manufacturer datasheet:
- 2x 38 W into 4Ω at 18 V, 1 kHz, 10%THD
- 2x 34 W into 8Ω at 22 V, 1 kHz, 10%THD
- 2x 24 W into 4Ω at 14.4 V, 1 kHz, 10%THD
- 2x 15 W into 8Ω at 16 V, 1 kHz, 10%THD
- 4x 13 W into 2Ω at 15 V, 1 kHz, 10%THD
- 4x 11 W into 4Ω at 18 V, 1 kHz, 10%THD
- 4x 7 W into 4Ω at 14.4 V, 1 kHz, 10%THD
Also, someone has tested the output of the power supply, it was 16,87Volts, but I do not know under what circumstances.
Therefore, I recommend something around 18V power supply for your system. A laptop power supply, usually rated between 18-20V will be ideal.
@@ridelifewithgrace4834 Thanks a lot man. Very helpful. Much appreciated!
isnt it bad to put a stronger psu in ?
No it isn't the PSU will supply 12V until you hit it's max current. If you don't hit that max current then any two sized PSUs are functionally identical.
Thank you for this excellent video!
