Hi.
I have some problem with old CRT TV Samsung model: CW-29Z338T, 29" size TV.
The problem is that letters and other text are not clear, text or letters are shadowed on the right side.
I found 2 capacitors on CRT Picture Tube Board.
47uF/400V was leaking very bad, the second cap 10uF/250V was bad ESR reading so i replace this cap also.
Replacement these 2 capacitors did not help nothing.
I try to reduce brightness, contrast and sharpness. There is very small effect on this shadow.
To reduce G2 down have more effect... -
