This Tv was shutting down after about 5 seconds . I found the vertical op and a 5v zenner To be the cause of this problem . I have replaced them and now I have vertical calapse. but there is no vertical signal comming from the signal processor ic. My problem is this Ic. The # is TA1242N (Toshiba). There is no NTE listing for it, no matches found on toshiba's website and I havent been able to locate it any where else on the net. Is there another Ic that can replace this one? Thank you .
