Monitor LG Flatron W2234S-BN

Recommended Posts

Am un monitor LG Flatron W2234S-BN la reparat care nu porneste, nu se aprinde led-ul de standby, tensiunea de 5v este buna, si ceea de 3.3v si ceea de 1.8V sunt ok. Tensiunea de 16v pentru invertoare este de 18.5v, presupun ca e mai mare ca nu consuma invertoarele. Placa sursa :ILPI 091 REV:APlaca display (display board): 491441300100RAre cineva vreo sugestie ce ar putea fi ???Condensatorii din secundarul sursei sunt ok

Tensiunea de 16V este mai mare pentru ca nu ai consum , asa ca , verifica CCFL_urile separat.

In loc de 24C02 va merge cu 24C08.Pune-o goala sa vezi ce face.

Pentru orice dubiu am verificat si lampile cu un invertor separat si sunt bune. Nu stiu cum as putea sa dau comanda de ON ca sa porneasca invertorul fara placa display-ului. Se poate ?
