![]() Hello
I have got a defective Philips HTL6140B/12 SoundBar, no power from button or remote. The power supply is external and working correctly, even tried another one. Checked caps with esr meter and all seems ok. Checked various resistors and smd capacitors and they seems ok. Please help to diagnose this SoundBar. Thanks ![]() |

![]() I can see that they used the type of glue that gets brown and conductive and corrosive of metals. You should carefully remove it.

![]() Yeah, i just noticed it and measured, and it is conductive.
What method can you suggest to remove the glue, and that it wont damage the traces of the ic and the surrounding components? |
