Thank you for this video, it was a big help in repairing my own JBL Venue Sub10 which happened to have the same problem. Wanted to add a note here though: those two capacitors are actually non-polar, mine were still intact enough to read the labels, so that’s what I put back in there. Works great!!!
Hi, I am trying to repair the same board, waiting for the parts to arrive. You’re video was very helpful in opening up my unit. The NP of C16/17 in the schematic means Non Polar, often used in audio.
Hi. I have a HK TS-11 sub and I have this problem. When turned on, the blue light normally turns on and the beep sounds for 2-3 minutes and then disappears. Sometimes it helps to lightly tap the panel on the back, but it also helps for a moment. What could be the problem, can you suggest? What to replace? Thanks and regards
Impossible to say without a full teardown. There are two boards, a power supply and a HK control board which feeds the power transistors. Suggest you open up and check for obvious capacitor failures first (bulged or popped).
@@pescado99 I am asking because one user on YT told me to replace the elements called "Q501 and Q502" but it is always good to ask for other advice as well;) And as for your suggestions, what you wrote about is all nothing bulging and no burns can be seen, etc. e.t.c.
I say 'failed' because the sub worked briefly during testing (although the green pilot LED didn't switch on and off), and then it failed - the same 2 x caps didn't fail again - something else let go. I managed to get it going again briefly, then it died again. So now it's sitting on my garage floor!
@@pescado99 thanks mate, there is another YT clip showing how to fix a TS11 : replace the 2 big resistors and Caps with higher wattage ones and put cooling on the 2 transistors in the blackened area .. .I'll start by replacing the 2 blown caps. see : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HszDDN6HOCY.html
