Philips defect ciudat


Guest 3fxw

Recommended Posts

am un Philips 21GV1260 (sasiu GR1AX) si are urmatorul defect: incinge foarte tare finalul de linii, astfel incat la 10-15 min de functionare se ambaleaza termic si il arde (de obicei scurt C-E). am inlocuit dioda de recuperare si condensatorii aferenti, verificat rezistentele din zona, totul pare ok. are cineva o idee ?

 

scheme la: http://www.eserviceinfo.com/index.php?w ... ring=GR1AX

 

multumesc

functioneaza aparent normal, imagine buna, audio bun, functii normale. tensiunile in zona sunt ok (conform schemei, iar Ua=95,5V / am incercat inclusiv sa scad tensiunea de alimentare pe linii la 90V dar efectul e acelasi). voi verifica si zona deflexiei si revin (nu verificasem plecand de la ideea ca imaginea e normala, ne-deformata).
