Como testar Resistor na placa? (Parte 2 de 5)

Instabilidade com o Multímetro

O maior problema de medir resistores na placa com multímetro é a instabilidade. Componentes como capacitores e transistores podem confundir a medida.

Por exemplo, Resistores com capacitor:

Quando houver capacitores na placa, a medida de resistência pode ficar instável por vários motivos:

- O capacitor pode estar carregado. O capacitor gera uma pequena corrente que confunde o multímetro fazendo o multímetro mostrar valores totalmente irreais. Não adianta descarregar os capacitores, pois é o próprio multímetro que carrega os capacitores da placa.

- Enquanto o multímetro não carregar todos os capacitores da placa, o valor fica variando, e às vezes nunca para de variar.

I apologize for sounding conceited, but I'm just totally thrilled that I figured out a way to remove the bezel of the television without destroying it. :-D

(Sorry about the camera strap in the photograph. I was in a hurry.)
So, I have a stove in my kitchen with a ceramic cooktop. As a result, I have one of those CermaBrite plastic...y a few dollars. :-)
Next steps are to remove the LCD panel, circuit boards, identify and remove the offending capacitor and then purchase a new capacitor and solder it in. :-)
This is going so well that I'm going to head over to the Radio Shack in town to see if they have the right capacitor I need. If they do, this television may very well be back in service around supper time! :-)
