Hello I have a Panasonic ct27g12v TV. Just had repaired, worked great for a couple weeks.
Now, I have a raster, but no sound or picture. The controls will change channels and all that but nothing but raster. When I select for video, I see the word video at top os screen but the screen is not blue like it is supposed to be, and still no sound or picture. Can someone tell me what the probable cause is? Thank you very much. curt
