Tisztelt szakik!
Említett készülék a tulaj elmondása szerint menet közben kikapcsolt.(készenléti led sem világít)
Hálózati bizti oké volt.
Tápegységben az R803 3.3 7W ellenállás megszakadva!
Csere után próba: kivágta a hálózati biztit és ugyanaz az ellenállás megszakadt!
Jelen esetben Zárlatossá vált a Q804 triac T1-T1 pontja mely TIC206D vel lett pótolva.
plussz ellenállás és bizti csere, és a készülék pazarul üzemel-cserélt ellenállás minimálisan triac nem melegszik.
üdv.
Udv tisztelt sorstarsak!Fent emlitett keszulekben sorvegfok halala kovetkezett be!Kornyeket kimerve nem talaltam semmi gyanusat.Tapfeszultseg 120V,impulzuskondi ok,megis csere utan az uj tranyo azonnal elpukkant(cso toltodese mintha tul nagy lenne).Driver betaplalas 45v,szurese jo.Trafocsere(uj).Jelenseg ugyanaz.Eredeti tranyo,ST1803DHI helyett,2SC5296 ment bele.Ennek jellemzoi hasonloak az eredetivel,legfeljebb melegednie szabadna,nem eldurrannia.
Otlete valakinek.
Tisztelettel:Feri
Hi
I am having trouble finding any information regarding this product.
The unit powers up and the output is displayed on the screen for between 0 and ten seconds, the unit then powers down, the red standby LED on the front of the unit blinks then remains off for 5 seconds then blinks again.
This cycle continues until the power is disconnected, if the power is reconnected the unit goes back in to stand by (red led steady) it will then power on again.
Also in the error mode (red led blinking) and the power button on the back of the unit is pressed twice it will power up but this does not happen if the remote is used.
I have tested various capacitors and diodes but all seems well, I have also replaced the power supply with a reconditioned unit but this has not helped.
I have been unable to obtain any service information for this product.
So any input would be most helpful.
Thank you
Stephen Fry

Fent nevezett gép kikapcsol ahogy bekapcsolnám és a készenléti led 7-t villog.
Elvileg tápok rendben lennének.
Valakinek ötlete?
Köszi
Jah Y board cserélve volt de nem az a baja ahogy az eurasban is írták - volna -. Köszi
