Hi i have a harman kardon hks 210sub/ 230 subwoofer and it has the same power card as your jbl, There are a few things I'm curious about about 1. Is it possible to further strengthen the subject bass? 51 ohm 1w resistor with 2nd thread FTA14N50C MOSFET, what can be installed instead of more convenient to have a long service life? I would be very happy if you could enlighten me on this matter.
Love your videos bro, really wish you said what reading on your multimeter made you think the transistor had an abnormality/what a good transistor reading would have been. I subscribed! Keep making electronics repair stuff, you have a valuable skill/talent!
Mabuhay po! My JBL subwoofer won’t connect through Bluetooth but it turns on. It’s pretty much brand new. I’m going to try and open it and see what it looks like inside.
Hello Mr. HandiDIYman. i have a von subwoofer ves3505es it works fine when at low volume but suddenly the sound becomes ditorted when i raise the volume...The subwoofer used to work well initially, what might be the problem. I have checked for mechanical damages to the speaker and cant find any
Thanks, try to isolate the problem by removing all satellite speakers, only subs , then try to check the sound, if abnormal , maybe the sub speaker is the suspect, try to record the sounds and send to my messenger PhroseTech Electronics, i will guide you
You bought a scrap product most probably. They usually sell a lot of scrap stuff with no quality control in local supermarkets even international supermarkets if you are living in a 3rd world country
