Menet közben némult el, lement készenlétbe azóta nem indul, gombnyomásra kattan a relé, aztán vissza le, más életjelet nem ad, tegnap este belenéztem, szerintem a trafója adta fel a harcot.Valamelyikőtök találkozott eme hibával?
Sziasztok!
Vásároltam ezt https://www.aliexpress.com/item/TDA7492-50W-50W-100W-D-Class-Digital-Amplifier-Board-AMP-Board-with-Radiator/2008916743.html a modult.
A leirásban szerepel állitolag hogy mono blokként 100w-ot is tud./valoban max 50W/
Jelenlegi állapotában olyan 20-25Wot tud torzitásmentesen.
Kérdésem az lenne hogyan lehet hidba kötni?/kiváncsiságbol is :-) /
Eddig nem találtam rola semmit.
üdv:Atis
Hi,
I registered mostly to flag this issue :
- current database has this file
https://elektrotanya.com/polkaudio_psw10_sch.bmp/download.html
which is a completely unrelated schematic that is NOT for the PSW10.
- I uploaded a better schem :
https://elektrotanya.com/polk_psw10_schem.png/download.html
but currently it's (incorrectly) shown as a duplicate of another schem on this page:
https://elektrotanya.com/show_rawsch
Is it marked as a dup simply because the filesize matches ?
Best regards.
Sziasztok!
A fent említett förmedvény került hozzám.
Standby-ból látszólag indul, kijelzők élednek, de gombnyomásra bizonytalanul jeleznek és a ledek elég halványak.
A 12,7V helyett 8,9V van 7805 3-as lábán.
Hálózati indító relé nem húz meg!
Standby tápot átnéztem, hibát nem találtam.
Leválasztottam a készülékről D4915 és 4916 felemelésével, külső pufferkondival 17V-ot ad üresbe tehát valami meghúzza, de nem jövök rá hogy mi a franc.... Van valakinek ötlete?
