VES236WNTC-2D-N01 lipsa imagine


Recommended Posts

TV Toshiba cu 17MB140

Placa display V236BJ1-P01 Rev.CB echipata cu IN518 si IN1802A

Alimentare cu 12V.

12V prezenti in anumite puncte.

O tensiune produsa de IN518,marcata ca V33V,presupun ca 3.3V este doar 1.8V.

Restul tensiunilor,VGHP VGL ... lipsa.


La o prima verificare nici o dioda sau condesator nu pare a avea o rezistenta prea mica sau scurt.

Datasheet la IN518 nu am gasit.

Are cineva ceva date despre acesta?

PCB este jos.

Alimentat separat cu 3.3V consum cam 70mA,aparent nu pare a fi ceva consum mare sa nu faca fata integratul.

Am mai gasit un 5V pe un pin al integratului,posibil un LDO intern.


Cu spray freeze pe IN518 la pornire apare si 3.3V dar atat.

Mai este un convertot DC-DC in acest IC,ceva step-up,12V,bobina,dioda dar nu porneste,dupa dioda sunt tot 12V (minus ceva cat e caderea pe dioda) deci nu porneste.


L-am dat deoparte,nu are rost sa mai pierd timp cu el,nu am gasit pe vreun alt display IN518 sa-l schimb.
