On this TV the problem was dead, I check everything or the usually parts all look OK. the next step I resolver the chassis and then the TV come on. But the costumer toll me before the TV went dead they had some problem with the sound some channel has sound and some don't. so I check the sound and I found some channel like 3 or 9 have no sound and the other one has it. I check if the TV was in SAP and turn it mode off but still those channel has no sound. I note when I turn the TV OFF and ON again I see in the screen the SAP was on again and I know I turn it off with the remote. Do someone Know what can cause this problem? (I have no diagram for this TV.) Thank you for any help. Jose.
