Replacement Power for a 5.1 Speaker system [Unsolved]
Hey
i bought a second hand surround system for my pc of TradeMe (New Zealand Auction Website) and the guy selling it said there was something wrong with the sub speaker.
anyway i got it a few days ago and found that the insides had caught fire obviously from a power surge, i replaced the diodes that caught fire and a IC that cracked. but when i tried to power it up the Power transformer got really hot within 20 secs and started to smoke.... That's not a good sign...
i know for a fact that i did not cause this but the previous owner did maybe from trying to get the thing going.
My question is, i cannot find any transformers that output the same power as this one it takes 220~240v input and outputs 12v~0.9A and 10v~1A
i can find a transformer that outputs either 10v or a 12 easily but not both
What can i do? if you need pictures i'll be more than happy to supply them for you.
im not sure, it could be that one is used to power the Sub speaker and the center speaker, and the other power source is used to pwer the rest of the speakers
You might not always get the answer you're after but you'll usually get an honest answer.
I'd concur with the above. You can pick up a half reasonable 5.1 system for less than $50 (£35) or you could throw good money after bad trying to find out why yours isn't working. You might spend $20 or so getting a new transformer only to find out the fault is elsewhere.
Forgot to say - try powering the transformer without connecting it up to the PCB - if it doesn't get hot then it may well be ok with something on the PCB causing the problem.
Yeah!! don't lose the flow man, get a 2nd hand hi-fi's from late 80's or early 90's, they work and sound much better that the modern chinese crap...
I say that, because majority of people today prefers crap stereos with blinking lights, huge useless LCD's and 10000000 W PMPO, and left the good old-school used equipment for us
