20 Most Recent JVC TH-M505 System Questions & Answers


Well i had exactly the same problem, my sub turned off right away when i turned the whole thing on. Well i opened the subwoofer and was trying to find out something unusual, i took out, i believe, internal amp, well, whatever that thing is, under the lid. Which one is screwed with 6 copper screws, so you unscrew those screws, lift that lid and that whole board comes out. On that board i find something like burn around one of the parts.

you can see it in the pick, the part q2902, then i contacted JVC. At the beginning they said i need to take the whole thing to service center and so on. But later i made them to tell me what kind of part that is, so here :http://www.jvcservice.com/store/ProductDetail.asp?Part=KTC3199/GL/-T

Hi,
Please confirm that unit gives sound output on System Connector J1103
I have schematics of this unit and can assist you to hook RCA jacks for all 5 channels output (L+R+C+SL+SR)
Thanks.

MOst of the time it is the jack that the cable plugs into that has the problem. .
Also the jack is not broken but HAS broken the solder connection TO the jack.
If you know someone who can safely take it apart and solder, let them try.

TH-M505 can display in black in white if connected iimproperly using COMPONENT connections or if cables have gone bad. Try replacing component or changing connection to COMPOSITE. Does it play in black in white using COMPOSITE?
