Am acest tv care se manifesta in felul urmator:

Dupa 5-10 min de functionare se opreste si daca ii dai comanda din tlc sau butoane porneste si ciclul se repeta.

Mai are un defect pe imagine dupa cum se poate obs in filmulet.

Tensiunile pe sursa sunt comform schemei. Pe sursa are un pin Error pe care normal am 0.3v iar inainte de a se stinge apare 3.5v(deci clar primeste eroare din placa digitala zic eu). Am pus Error la masa si nu se mai inchide dar din cand in cand se sting neoanele dar sonorul ramane.

Am desfacut panelul gandinduma ca poate are descarcari la neoane dar nu are.

Pe OSD nu apar acei purici daca le pot zice asa. Am atasat si o poza cu Placa digitala(ce am inercuit cu rosu a mai fost umblat in el)

Proprietaru zice ca a mai fost cu el intr-un service si ca nu facea purici pana al duce in acel service.

Umbland prin meniul de service am obs und camp unde afiseaza erorile. Si am o eroare care apare de mai multe ori: power_off_by_inv_error(problema la invertor). Am masurat tensiunile sutn ok, am schimbat condensatori electrolitici, am refacut lipiturile, am anulat protectia si tot se stinge. As vrea sa rezolv problema asta cu sursa. Paroblema cu imaginea cred ca e de pe selector. Pe vga se vede bine fara distorsionari.
