Luxman L-100 "winker" and "ON" bulb do not light up
Hi, I am working on a Luxman L100 belonging to a friend. I noticed the following problems. a) It takes about 12 to 15 secs for the relay to turn ON. b) The relay does turn ON but both the "winker" bulb and "ON" bulb do not light (both the bulbs are OK) c) The "touch MUTE" is not working. d) When switching on the 10Hz low cut filter, the relay cuts off and does not come ON until the switch is set in the centre(bypass). Can someone familiar with this amp, please help me out Thanks Carlos "FONTOS! Olyan fórum téma nevet válassz, ami beszédes, minél pontosabban illeszkedik arra, amivel kapcsolatban írsz. Egy lehetséges jó elnevezés pl: ORION LCD PT26S chassis 17MB12-2, a tápja nem indul Az nem elég, hogy pl: "LG LCD-TV" vagy "HP laptop" és hasonlóak. Illetve érdektelen, nem releváns információt se tartalmazzon a cím! A helytelenül elnevezett topik felfüggesztésre [F], majd 48 óra után törlésre kerül! Felfüggesztett állapotban nem tudnak mások addig hozzászólni, amíg ki nem javítod a címet. A hibás cím utólagos javítása (48 órán belül) a "Szerkesztés" fülre kattintva végezhető el." "IMPORTANT! Select a forum topic name that is descriptive, more precisely matched to which you're writing about. A possible good name eg, ORION LCD-2 17MB12 PT26S chassis, the power supply for will not start It is not enough, for example: "LG LCD TV" or "HP laptop" and the like. And do not include irrelevant information not relevant to the title! The incorrectly named topic suspended [F] and will be deleted after 48 hours! Suspended while others are not able to speak until you correct the title. Subsequent repair of defective title (within 48 hours) by clicking the 'Edit' tab to be done."
Hitachi TRK7990 Rádió-magnón LCD kijelző nem működik, Urh-n csak zaj van
Sziasztok!
 Ha valaki tudna tippet adni, megköszönném. Próbáltam rajzot kérni az SM-keresőn, de sajos nincs (igaz, csak TR7990-et írtam, hibásan) Ha legalább ebben volna segítség, már annak is örülnék.
Köszönettel:

Hollywood impact 1000 végfok,védelem hiba
Sziasztok!
Hollywood IMPACT 1000 végfokot javítanék,de elakadtam,mert a koppanásgátló relék nem húznak be bekapcsoláskor.
Ha összezárom a vezérlő tranzisztor lábát akkor a relék bekapcsolnak,és tökéletesen szól,a végfok rész teljesen rendben van,a kimeneti feszültségek is 10-20 mv körül vannak,az LM324 ic-t is kicseréltem,a régi is jó volt ezek szerint.
Kapcsolási rajzot nem találok hozzá akkor talán könyebb lenne,a kis tranzisztorok is jónak tűnnek,diódák is,kondik is,ellenállások sem szakadtak.
Valakinek van valami ötlete,hogy mi lehet a baj?

Köszönöm előre az esetleges segítséget!
