[tim_spur]

i have a galaxy mirage 88 was having problems with no audio so put a new audiochip in now as soon as you hook it up to power it melts the protection diode put another new diode does the same thing whats wrong here

hey there,you are installing the audio chip correctly ahy.it has to be installed with the numbers facing the heat sink.also check your solder connecions making sure two patterns are not touching each other.

well i installed the chip in the exact way the old one was in with numbers facing the inside of the cb and was carefull not to bridge any connections is that the wrong way

[ramblingman]

yep,thats the problem,youve installed it backwards.the numbers on the audio chip should be facing the heat sink.in other words you shouldnt be able to see the numbers once its installed,the side that has the little round dot in the middle,should be facing the inside of the radio.better put a new one in now through.cause that ones probably toast.........ramblingman
