attilaa0 Posted July 17, 2017 Share Posted July 17, 2017 (edited) Buna ziua!Am o problema cu aceasta sursa ,dupa ce am gasit FSD200 explodat ,dupa inlocuire sursa de 5V de st-by palpaie ,ledul de la tv palpaie si din sursa se aude un tic tic ca si cum ar fi ceva in scurt,dar nu este. Banuiesc ca ar fi ceva in partea primara dar nu vad ce ar fi.Am inlocuit condensatoarele .Face la fel.Am masurat diodele totul e ok. Astept pareri.Va multumesc! Am incercat sursa si fara tv si face la fel. schema e aici:https://elektrotanya.com/profilo_05ta132d_power_supply_sch.pdf/download.html Edited July 17, 2017 by attilaa0 Link to comment
dan cod Posted July 17, 2017 Share Posted July 17, 2017 Daca bine imi aduc aminte cand pusca FSDul mai pica un tranzistor si o dioda. Link to comment
cristronic Posted July 17, 2017 Share Posted July 17, 2017 Poate sa fie chiar trafo chopper defect sau FSD200 de proasta calitate.Se poate monta o sursa de 5V separat. Link to comment
attilaa0 Posted July 17, 2017 Author Share Posted July 17, 2017 Am incercat cu o sursa de 5V separata si merge,Trafo chopper exclus ca are 4ohmi si am vazut pe un site unde se vinde chitul de reparatie ca trebuie sa aibe 4ohmi.Am verificat bineinteles si componentele oferite de kit. Am inversat optocuploarele.Nici o diferenta.Am pus alt FSD,la fel face. Link to comment
