Szevasztok!
A tárgyban jegyzett gépezet javításával kapcsolatban kérek segítséget.
Semmi életjelet nem ad, töltést sem juttat az akkumulátornak.
A tápfeszt megkapja, ameddig rajz nélkül lehetett végig mértem a feszültség útját, de elakadtam. :(
Ismeri közületek valaki ezt a gépet, esetleg valami tapasztalat?
Az alaplap típusa: BA41-01978A HST
Kép itt van róla:

Segítségeteket előre is köszönöm!
Üdv!
Üdv! Érdekességként kérdezném, mivel csak pár hete van a gigabites (vodás) internet bekötve (eddig 500Mb/s volt, de nagyon belassult, szakadozott, használhatatlan volt néha), nincs vele nagy tapasztalatom, de feltűnt, hogy Firefox és Opera böngészőből, mindig jóval lassabb (370...420Mb/s) sebességet tudok mérni, mint Chromból (650...780Mb/s) ugyanazzal a progival. Eddig nem volt feltűnő a különbség, mert kisebb volt alapból a sebesség.
These are PC speakers, picture of the board here

Have replaced the TDA2030 IC's with new from stock, still get very hot. Tried now TDA2040 IC's, still run hot. Replaced all electrolytics
and even most the disc caps and the diodes for the bridge, and some of the small surrounding support resistors, really baffled....
Original problem seems to be they put too strong an input into the 3.5mm jack, and there was an MOV on the jack that shorted. Replaced it plus 2
other MOV's on the board. It seemed to be ok but played sound really too low, and only from the bass speaker. The smal L-R tweeters have never put out any sound at all...
they measure ok ohms, so they should work.
