hi all, I had a shut down problem with this set, found out that the 2 STK chips were bad; after replacing them, now I'm getting white-red trace lines accross the screen when the picture goes bright, but clears as picture gets dark; I disconect the module from the red picture tube and picture stabalized; could it be the CRT socket itself, the driver on the CRT module, or the digital convergence board? any ideas? thanks
