Hi I am using RCA TV model 20F512T.My tv shows green screen actually it is blue screen what can i do to change the screen.Plese guide me when the tv is on it shows green screen and MONO.
using a dmm check the resistors on the kine board. the small board on the back of the picture tube. you sould find an open resistor. if i remember correctly, if looking at the back it would be on the bottom of the board & about 180k ohm. if you have a difficult time finding it, look for the same type/color of parts on the small board to make comparrisons. between parts. you sould have 3 of most parts, one for each color. good luck.
