Sziasztok!
A címben szereplő Bluetooth-FM rádió-USB-hangszóróban lévő végfok IC típusát nem tudom leolvasni, mert megégett.
Hátha valaki látott már ilyet belülről és tud segíteni :)
Képek a készülékről és a panelről:

When the speaker is connected to the 220V network, a hum appears in the bass speaker after 1-2 seconds. There are no buttons that do not work, the red power-on LED is constantly on. What is the reason, where to look for the fault?
Sziasztok
kaptam 2 ilyen hangládát Big BT ZQS-6201 Speaker Party bluetooth Hangfal ami a bekapcsolás után kimondja és kiírja a kijelzőjére hogy power off az akkuk feltöltve nem tudok rájönni hogy miért kapcsol ki
elvileg távirányító is van hozzá de azokat még nem kaptam meg
próbáltam sd kártyát is bele tenni azt felismeri de nem játszik le róla semmit és gyorsan kikapcsol rádióra sem tudom átkapcsolni
Találkozott már valaki ezzel a szerkezettel ?

Hi - I have a pair of KRK VXT4 studio monitor speakers. Very expensive! When I stored them, they were working fine. When I tried to use a few days ago, one of them simply hums loudly at 50Hz. I have tried replacing the two 12000uF PSU capacitors, as I found on Google that sometimes they can become depolarised but this has not solved the problem. I am trying to find a schematic for both the main board (which has the PSU and the PA stage) and the pre-amp board. - Thanks, Kevin
