SF2717N speaker issue
3 Attachment(s)
Speaker issue here, and not sure what it would be. The front right speaker doesn't work. I did pull the back off and took a few pictures as I followed the line from the speaker to the back of the circuit board. Now, I don't know really anything about fixing TV's or speakers. I can fix pc's, and videogame controllers. That's about all of my skill set. I attached a few pictures hoping that I could be pointed in the right direction. I can't believe it is as easy as a blown speaker, but again I have no clue. Thanks in advance for any input.

Got a known good loose spare speaker? If so hook that to the terminals on the dead speaker. If the spare works then the one in the set is dead. If the connection does not drive the spare then the interconnect wiring or main chassis have issues.

My fault, it's the front left speaker (as your looking at the TV). I didn't have an extra speaker, but I did have an external speaker to plug into the external jack. The same issue of the left speaker not working is there, so is there a module or something like that to fix it. thank you for your reply.

Beats me. I don't work on anything newer than the late 70's Deltagun CRT Zeniths.
You will probably need to track down a schematic for it and some test equipment. If it is not a stereo set then the second speaker is unnecessary anyway. |
it is stereo, doesn't take away from functioning but once in a while the tv sound goes away when I'm presuming it is pushing sound to the other speaker. Thanks for the assistance

Perhaps swap the two speakers (or the leads) and see if the dead channel follows the speaker or stays on the same amplifier channel. :scratch2:

First where things are :
In front of the jack pack, on the main PCB is the audio out IC. Its on the heat sink. The jack pack has all the ins & outs. The SPKRS are the two wires that plug into the top. Try swapping them. Also you can do the swap right at the SPKRS. If the dead channel "moves" the problem is on the chassis. If not its the SPKR. ( SPKR plugs may be keyed). If on the chassis look for cold solder at the out IC & the jack pack. Especially look around any jacks that have been used a lot putting physical stress on things. One other thing to try is unplug the set over night then try again. That will cause the micro to do a complete reset & can solve a lot of problems. 73 Zeno:smoke: LFOD ! |
Thank you for all the help
