TV Orion

Recommended Posts

La un TV Orion de doi ani am schimbat TC,avand filament intrerupt {calitatea de azi,la Samsung}.Am uitat sa pun legaturile de masa la tresa tubului.La pornire a faccut o flama mica.Am refacut legaturile,si am pornit TV manual.Totul OK,doar din telecomanda nu face nimic.Am masurat pin la Proc prin care primeste semnal de la receptor infra,are 39 ohm,cam prea putin.Dupa parerea voastra sa dus exact pinul asta,si in rest nimic.Proc este ST92195C7B1/PFT.La Tavi am vazut cu /PAL in loc de /PFT.Oare sint identice.Mersi anticipat

cu 39 ohm pe intrarea de ir nu o sa mai mearga tlc decit daca schimbi procesorul,fiind cea mai sensibila intrare la acea descarcare sa defectat intrarea de ir.

Pe placa nu scrie ce sasiu este.Am gasit etichete patrate lipite pe placa dar cu litere si cifre.Pe capacul din spate scrie Orion P2850ST si pe randul urmator FTYCRPT90SBDGN.DE aici sa fie PT90 sasiul?
