tv orion t20ms receptor ir

Recommended Posts

Foarte simplu:improvizezi un mic montaj,un led emisiv in IR alimentat cu 3 volti printr-o rez de limitare 47 ohmi,si de cite ori pui sub tensiune ledul vei vedea la iesirea receptorului de IR impulsuri,bineinteles nu vor fi recunoscute de procesor,dar vei ajunge la concluzia ca receptorul de IR functioneaza,metoda asta e valabila la orice tv,si alte utilaje.

Asta inseamna ca telecomanda emite ceva ,nu se stie daca ce trebuie si ca la procesor ajunge semnalul de IR.Primul pas ar fi testarea telecomenzii pe tester qunda .

telecomanda e functionabila,eu le testez pe un aparat radio pe UL sau UM.Am mai cautat pe net,ce model s-ar potrivi la acest tv,am ajuns la concluzia ca cel mai potrivit model de telecomanda ar fi 076L078090 iar telecomanda cumparata de mine e 076L078030.Ce parere aveti,e posibil ca 076L078090 sa fie cea buna?
