Hi. I just fixed a Sceptre X37. I had no idea what was wrong with it other than it didn't power on. So I found the problem to be the PSU shorted on the chassis through the thin peice of plastic. So I re-soldered the transformers that shorted (it stopped working because the solder melted off). Then on the board where the inputs are, 2 resistors started to smoke up (after having the TV on for a few minutes). So I replaced those. Now the TV is working fine, and I have my Xbox and Dreamcast hooked up to it. Problem is I have no sound. I don't know what on here produces the sound or if there is something I can replace. Help please?
