Problema in monitor Dell ultrascan D1626HT/U

Am o problema ciudata cu un monitor Dell/Sony, (am descoperit ca Dell ultrascan D1626HT/U si Sony GDM 500PS sunt identice).

Am gasit caietul de service aici: http://rv6llh.rsuh.ru/shema.htm

 

Defectul: imaginea tremura in partea de jos a ecranului. Masuratorile cu osciloscopul nu evidentiaza nici o oscilatie parazita pe cadre. Am schimbat in lipsa de solutii LA7841, bineinteles ca merge la fel.

Condensatorii din zona lui LA7841 sunt toti OK, problema e alta.

 

Daca cineva a mai intalnit problema asemanatoare in oricare din monitoarele Dell sau Sony (mai sunt si alte sasie identice) e rugat sa dea o solutie.

 

multumesc,
