LED Samsung UE32J5200AWXXH nu porneste


Recommended Posts

Salut

LED Samsung UE32J5200AWXXH

MB = HIGH_NT14M_2015_UNION_J4303 BN94-08318A

Panel = CY-JJ032BGLV4H

Sursa externa 19V

Ledul de st-by palpaie la nesfarsit, la apasarea butonului power de pe tlc sau panou se mareste frecventa flashurilor dar nu porneste.

Sursa scoate 19V ok, pe MB am masurat ceva tensiuni si par in regula, 19V; 12V; 5V; am 3,3V pe mem 25Q40, radiatorul procesorului este caldut

Pe modulul T-con tensiuni ok si are doua leduri care se aprind pentru vreo 5 sec dupa care se sting si iar se aprind si tot asa.

Am decuplat pe rand T-conul, modulul WiFi, backlightul dar nici o schimbare ledul de st-by tot asa palpaie.

Ce parere aveti, cine blocheaza pornirea ?
