Nasol. Vezi ce rezistenta ai fata de masa pe VGH. Daca ai noroc poate gasesti un cond smd in scurt. Daca nu este scurt sau rezistenta foarte mica vezi de ce integrat (convertor dc-dc) este legat punctul de masura VGH si-l inlocuiesti. Daca tot nu apare posibil sa ai un scurt cel mai probabil in driverele laterale.

Daca poti intrerupe (sectiona) circuitul VGH spre integrat ar fi OK. Daca rezistenta ramane inseamna ce este spre panou si daca esti norocos gasesti un cond cu rezistenta. Daca nu, insemna ca este integratul.
