dan cod Posted July 16, 2014 Share Posted July 16, 2014 Eu am folosit in tvuri P11Nk60 si merge cu el in loc de fet poate daca consumul nu e mare si cu p6nk60(din asta am pus intr-un samsung sasiu care avea initial smr400 si merge si azi)In loc de ksp nu stiu daca nu merge bc639 verifica datasheetul.
