Hello Friend. First measure the voltage on the tuner pins if you have 33volt. + 5volt and 4.7 volt. on the agc pin. If you have those volt. disassemble the selector and solve it inside but be careful not to leave lines connected with the tin, and solve the insert of the trc. and the flayback pins and those of the ic. jungle. regards

good to the couple has two failures I see its spotted tube change the ptc and another is as if it were out of horizntal frequency can be some capacitor that works with horizontal frequency is fixed if it brings a horizontal preset or maybe it already comes out of the chroma greetings

Buddy, if you have those normal voltages, solve and stay the same, I have to change the whole tuner

if you see that everything is fine I try for AV audio video input if you bring with a DVD if you do those stripes even it can be chroma in poor condition

I gave it to the client since the husband was a bad drink and made me a bad scene in the workshop and I returned the TV thanks to everyone for their support I think it was still to change the tuner
