Mackie ProFX12 V2 Request for schematics and repair knowledge
Hello, I am in the process of repairing the Mackie ProFX12 V2 mixer for a client, and am running into the unavailability of schematics. Does anyone have a copy they could share? I have already reached out to Mackie directly but am still waiting for a reply.

Additionally, I am having trouble identifying the failure mode for the two channels that have failed: one produces loud static (indicating bad op-amp or feedback resistor perhaps?) and the other has the right channel producing a 60hz hum, the other is functional. (see board photos, with the two failed channels being marked with "F". The browned area is residual flux from having replaced two opamps, and having reflowed other components around them)


Any help on either of these fronts would be invaluable. I have mainly worked in laptop and computer repair, and am just getting started with my first scope and first set of board level repairs. 
Hangszórók & Hangsugárzók...információk!
Hello. Van néhány (számomra) ismeretlen hangszóróm...amelyekről "csupán" több információ kellene. De van olyan is, amely típusból kéne még egy darab, mert párosan jobban felhasználható volna. Meg vannak javításra szoruló példányok is...és majd meg is válnék 1-1 darabtól. ...és bármi ide írható ami a topik címével kapcsolatos, hogy egy helyen elérhető legyen. Van ugyan néhány hasonló című topic a Tanyán, de univerzális címük ellenére, csupán 1-2 típusú hangszórót tárgyalnak bennük. Hajrá... Üdv.: uniman
JBL On Time Micro lefagyott
Tápfeszre bejelentkezik, óra megy, de gombokra, bekapcsolásra nem reagál.
Működött, változás egyik pillanatról a másikra.
Van ötletetek? Mikrokapcsolók állapotát ellenőríztem, egyik sem tűnik zárlatosnak.
A fotó még a működő állapot szerinti.
JBL Charge 4 Bluetooth hangfal "vágja" a hangot
Sziasztok

JBL Charge 4 Bluetooth hangfal kis hangeron normalisan mukodik, ahogy kezdem hangositani, pattan egyet es tobbet nincs hang.
A hangfal bekapcsolva marad, a ledek egnek rajta, a BT kapcsolat is megmarad.
Nem tudok ujra hangot kicsalni belole, csak ha kikapcsolom es visszakapcsolom.
Futtattam rajta egy firmware frissitest, de nyilvan semmi sem valtozott.
A toltottseg nem szamit, teljesen feltoltve is nemul.
En akkura tippelek, de konnyen megmerni sem tudom . Szetszedtam annyira, hogy hozzaferjek, de meg a tuskek is be vannak ragasztva olvasztott muanyaggal a hazba, azon nem tudok merni.

Kerlek adjatok tippet.

Minden jot,
Janos
