the image looks double even without a signal, it all started that the video suddenly left but if there was audio, the check and resolved some cold welds, and there was video again but it appeared with a ghost or double image, I checked again to see if some revava was making short but all normal, I really don't know what to check and check all the cards and solve some cold welds but nothing ... if there is dideo and audio the only problem that looks double

Hello, what you say is rare, generally the problem of ghosts is attributable to signals from a channel that arrive at TV at different times, due to some rebound, this was quite common several years ago on black and white TV, it could also be that the convergence fins of the tube would have moved, verify this greetings

the convergence fins did not move, and the truth is I don't know that checking could give me another solution thanks

patroncolor.png [39.79kb] compañero.- is an image that go with "ghost" as suggested by Master Pr122.- Or it is a "double" image that is out of horizontal synchrony. If it is the first then: from a bn tv that has an input transformer, (isolated from the network) you take two cables, one black that will go from the earth delbn to the land of your color TV.- another yellow that will be connected to the fi from the bn and at the other end of the cable you connect a 0.022uf ceramic capacitor. on the other side of the capacitor you connect it to the fi of your color tv. (obviously you remove the original selector), tune the bn and it has to be seen in the color one. comment. greetings everyone. Felipe ascencio
