As it was mentioned, your best bet is to find someone who has the same unit. I appreciate if you can cooperate.

CRT Datasheet, PDF – Alldatasheet

Not sure but I think the picture was originally posted here; http: I guess the adapter is unable to supply enough current. Last edited by a moderator: Does it look burnt? I cr685t trying to repair the power supply but cannot figure out the values of the burnt parts.

I can see two resistors and a zener diode as burnt: Solder Guy New Member Jun 13, That’s my last resort.

Solder Guy New Member May 25, Can’t spot any datasheet for that IC in a quick search. My current guess is 4 burnt parts right to left: Just saying hello Started by MichaelaJoy Yesterday at 6: I think your best hope is to find someone with the same model supply and get the values from that. Some of the parts are pulled out but you might open it up in a separate browser or an editor for blow up, I think you can see the bandsby the way it is going to be more than the resistors faulty. The optocoupler has some lines on the edges.


Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I guess it means it can withstand high voltage but not sure.

I think the lightning damaged components on the amplifier too umar: It could also be the card scheme. Click here to register now.

It was able to supply the current but lot of static noise was datashfet. In the mean time, there is a hi-res picture of exact power supply happened to be posted on a Turkish forum! Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Hello ladies and gentlemen.

I would have never thought about the Turkish forum. I have adapters till 3.

I think the power requirement is 4. You must log in or register to reply here. Most ICs on the amplifier board have large heat sinks on them so its not easy to point.

Creative A520 Speaker, burnt power supply in lightning

Creative A Speaker, burnt power supply in lightning. I also figured out the diode to be a 1N high speed one.

Can anyone please confirm these 4 encircled components? Started by fastline Yesterday at 8: Now just the resistors need trial and error. Potentiometer Questions Started by norbss Yesterday at Also the copper in some speaker wires had black dust carbon?

I think the diode was used to fatasheet PWM and after its blown the whole unit shutdown. I think I can put some combination of inductor and capacitor to filter it and then the speaker will work even better with it.
