OK I just finished what I was hoping to be a really simple experiment with my sonic impact t-amp. I replaced the little red led with a white one that has full length leads so I could mount it on the box so that it shines through the front. I finally get the old led out and the new one in, shines very brightly and looks great. Now for the problem... after doing this I only have sound from the right channel. I've switched left and right and the problem follows the speaker. I've tried different sources -- not the source. The only thing I can think of is that when I was trying to take the old led out I go the circuit board too hot and fried something... I don't know enough about this stuff yet so if you have an idea of what I did and how to fix it (other than the obvious - buy a new one) please lemme know. BTW unfortunatly installing the original stock led is not any option anymore... it was mildly mauled in the removal process.
