Disconnect the LVDS cable to the Tcon board (wrap a plastic cover/bag around the connector to prevent accidental shorts between the exposed panel metallic casing with exposed contacts on the connector). Plug the monitor to a PC, and just pause it on the BIOS setup screen (keep tapping the BIOS setup key when power on, no need to boot all the way to Windows or any other operating system). This should present a white screen. Does the "ghost image" still appear on this white screen?

Hi,
Thanks for replying, the ghost image in the attached pics is when theres no connected cpu, i can see the no connected input box moving around the screen but blurry, is it a bad panel?

Bad panel is a possibility. First, try cleaning the LVDS connectors. Then check the voltage to the Tcon board (to see whether there is a problem with the 3.3V regulator or MOSFET that controls power to the Tcon board). I would recommend changing all capacitors in the power adapter (to rule out ripples going to the panel). Also replace any electrolytic capacitors on the main board. Do use good and recommended capacitors such as Panasonic FM, Panasonic FR, Nichicon HE, Nichicon PW, Panasonic FK, Panasonic FC, Nichicon PS, Nippon Chemicon KZE, Rubycon ZLJ, Rubycon ZLH, etc...

Looks like the VOFFE or VONE voltage is missing, any part# for LCD panel (on sticker marked e.g. SAMSUNG LTI19A####, AU OPTRONICS LXA19######, etc.)

Re: Samsung S19A100N ghosting picture..

The panel is the fault, the only fix is to replace the whole lcd, and finding a replacement is difficult, so i've given up on this monitor and bought a new one.
