Good evening: Receive a warm greeting: This fault occurs in a SONY TV model: KV-25FS12 / 5 year 2001 [list] [*] When you turn on the TV, you can see a transparent pink layer with the very marked recoil lines. [*] You can see behind this transparent layer the image of the selected channel. [*] The TV pays shortly (approx. 30 seconds) as if it were a protection failure. [/list] Thank you very much, regards.

It measures the tensions of scrin-chroma. then scrin decreases just to see those lines disappear. if he returns to the state of tension he had and changes the electrolyte of the 180v. That does have audio. It can be problem in the ABL also controls that it has 8v or so.
