Well, the odd thing is this detachable speaker bar -- my information doesn't show a detachable one.
This is a picture of the TV set, and yes the speaker section does look separated from the display --
So it is possible that the TV does come in two parts for shipping....
Here is the speaker assembly totally broken down --
What I'm looking REAL HARD FOR is the CONNECTOR that connects it to the display to carry the Audio and the IR reciever and Power lamp signals ! That's what I'm kind of stuck on, because if YOU had it disconnected, installed it, then it worked, but NOW it doesn't....we always look for the obvious first like a plug that was partly plugged in, and is now Unplugged.
Other than that, your main audio processing board is bad, and we don't go there until we look at the obvious and the cheap repairs. Obvious is like the speaker on/off switch and the connector that must connect if the speaker assembly was shipped separated from the TV set.
Obviously Mitsubishi didn't include those instructions with the customer's installation notes, and I would have EXPECTED them to be including if it's separate.
Does not compute....does not compute....Error.....Errrrrror....( Kirk has Scotty beam TV Tech-1 off his ship where he explodes)
So TV Tech-1 gets miffed, regenerates, crawls back into Kirk's ship thru the plasma ducts, looks further into the situation, and discovers that there IS a CONNECTION !
Right there....right by the green box. Those wires go DOWN, so you had to have a connection to the TV's speakers, and what I need from you is VERIFICATION --
Now, that speaker that you got separately -- did you notice if that speaker looks like the one in the FIRST picture? That's part of the TV set, and I HOPE to God they didn't charge extra for that ! It's REAL ODD that Mitsubishi did not include installation notes in the customer manual , and I'm not going to explode again because it makes no sense to me.
What I'm more concerned about is the fact that if you had to install it, you had to remember a plug needing to be plugged in before mounting the speaker assembly. Obviously your power lamp works, your Infra Red reciever works with the remote, so logically your speakers should too -- unless you had TWO PLUGS that needed to be plugged in.
Now, looking EVEN CLOSER -- there is a 3 block connection point JUST FOR SPEAKERS....so if you didn't plug in 4 plugs, then those connectors MUST BE contact connections ! What I mean by that is you screw in the speakers, and the BODY of the speaker box comes in contact with pressure connections on the BODY of the TV cabinet !
Now THAT makes sense if you didn't connect anything together !
And if so....well the connections must not be making contact if all 27,000 tiny speakers are dead in the water.
That or the main board died....but each speaker has it's own little amp, and that is Very illogical...you don't blow 27,000 amps, you blow 1 or 2. Then you still get sound.
See how we have to ANALYSE your situation? I'd be looking for bad connection points, too much gap between the speaker assembly and the TV set, or SOMETHING in the menu completely turning off the entire Speaker system !
That's more logical....
Obviously I'm not there IN THE ROOM to check and see if you have some spring-loaded contacts on the plastic body, or if you have this SLOT that something pokes into from the other unit, or if you have a little tiny SUPER PLUG that you had to plug in per a separate set of instuctions, but you had SOMETHING to connect-- some how, some way.
Don't worry about the DVD and some separate amp...that has nothing to do with the sound...I was suggesting that you LOOK at the Audio settings for a speaker on/off setting, but you MUST Look at the settings when you have no sound on your TV set. Each INPUT can control it's speaker settings...you can have the TV speakers work on the Cable box, and have the DVD output it's audio to an amp with the TV speakers turned off.
So when you change inputs, the TV remembers how you want your Audio run.
