    samsung lnt4042hx/xaa blacks turn red

    ]hi I have a Samsung lcd lnt4042hx/xaa and the black keep turning red...I originally replaced the caps and it worked for about 30mis then went red again..next I checked/cleaned the lvds cable where it connects to the tcon and it worked for about 4-5 hrs (longest time yet) then went red aagain. could it be the ribbon cables going to the lcd or something else? any advice would be helpful. thanks

    plus it is the same on all inputs

          Samsung sets can test tcon,panel and scan boards. This test bypasses use of main board. A very helpful test. I have used it once on a LG.
