take a pic like this, and also one from underneath but in the same direction at the same area

take a pic like this, and also one from the bottom opposite side of board, aimed at same area

i'm wondering what's in the metal box. does it look like wires from the speaker ports are going into the box?

edited: these comments aren't for your most recent set of pics, but the one before it at the bottom of the first page. i hope after all of this it is in fact the fuse! i won't be able to take a pic for you because i have a different model! i got mine a long time ago. my power switch, forexample, is on the other side of the box. i'll continue trying to help you though. again, they aren't pictured. i think the fuses must be either on top of or below the main board in close proximity to the speaker ports. if you were to take a pic from the opposite direction of your first pic in the last series, it would have a better view of the board close to the ports. if they aren't there, then maybe they are on the other side of the board. focus on the area nearest the ports. mine looks much different-it looks like most your stuff is on one board, while mine had 2 or three small board connected to a larger.

still don't see it. take another pic. take the whole panel and turn it upside down relative to the top picture in your last post. i remember resting the whole thing on that metal box when doing the swap. if you turn it upside, resting on the box, the area you need to look is top left.

fuse is roughly diameter of ball point pen FILAMENT

just saw your pic. they aren't in view. the key area is out of frame both to the right and to the top. underneath that main board i think. so much smaller than those blue things (unless the scale is skewed because ofcloseup)

hi. i'll try to jump in here. the radioshack fast acting fuse works fine. be careful to get the small ones, not the big ones, which are noticably bigger. ok, i'm doing this from memory here. are you on the 2.1? can't speak for the 5.1 here. look directly behind the speaker wire inputs. a circuit board or two extends into the box. at the end of the board away from the back panel, you will see 2 or 3 wire clusters with white plastic connectors similar to those found running from your computer's power supply to its disc drives, etc. the most accessible of these wires is located between the two tiny fuses, which are situated perpendicularly to this wire, one on either side. for easy access, i suggest disconnecting the wire. it reconnects easily. i used a needle nose pliars to remove the burnt fuse, which is held in place with two clips. careful not to stretch out the clips when removing and inserting. i had to bend mine together a bit after inserting the new fuse to get a tight fit/clean connection. the fuses are tiny with silver ends and glass in the middle, with the similar proportions to an AAA battery but much smaller. this is almost useless--just in case: overhead xray vision view (fuses are under a board that would be between your face and this diagram, perpendicular to back panel.) _____speaker input_______ -underscore is back panel 0 | 0 fuse | | | fuse 0 ___ | ___ 0 | | wire with white clip good luck. if you are stuck tomorrow i can take a pic and let you know.

do you know what type? the fast blow 2.5a fast is just a straight filament, without the two bulbous forms. the 2.5a slow look entirely different, with a tightly wound perfect coil from end to end. thanks

thank you. you're exactly right. the fuse is blown.

Hi. Well, I thought I was slick plugging in two speakers into a single port. [H]Not anymore. [:'(]One of my ports is dead. My Left port will serve either speaker, my Right port will serve neither speaker. Checked my sound sources--it's the port. Can I fix this myself? Thanks for suggestions. Promedia 2.1
