MACKIE SRM650
Tápegységének javításhoz kérnék segítséget!
PCB_ LFPA_02490-0001
PWM_vezérlő L6599AD
kapcsoló fetek 4db G20N50C
kimenő villanyok: +-50V, +-15V +8V
A gondom, hogy instabil a kimenő fesz, / +-15V, illetve a +8V/
A +-50V nál a pufferek csúcsra töltve. / terhelés hatására lebeg/
Az egész panel fehér szilikon pasztával telehányva!!!
Forrasztási oldalról a kondikat ESR mérővel ellenőriztem.
Az SRM 450-é még véletlen sem hasonlít rá, egész más kapcsolás.
Csak ott bontanám meg a szilikont, ahol a hiba gyanítható!
Esetleg manuálét tudnátok a prezentálni? Akár meg is vásárolom!
Köszi Pozsgai
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.
