Re: Samsung UN46D6420 Horizontal lines, now No Picture

I have LA40D550 with same issue as OP, horizontal lines/ghosting is flickering in top 2/3 of screen only. Replace T-CON, issue persists. Caps look and measure capacitance fine. Next step is to check ripple on PSU rails with CRO, possibly check ESR of caps (if I can find/build ESR meter) or more likely check bonding of tabs like [url]https://www.badcaps.net/forum/showthread.php?t=25371&highlight=Samsung+LN52A530P1FXZA[/url]Re: Samsung UN46D6420 Horizontal lin...ith same issue
