Ghosts in the ... eh ... Samsung
« on: August 08, 2018, 04:24:23 pm »
I have a Samsung UE32D5000 television that suffers from ghosting; with each large change of the image, the previous image remains faintly visible for a very noticeable amount of time.

As it seems to worsen with higher temperatures, I am tempted to think this might be related to dying electrolytics. Before opening the thing up, though, I'd be happy to get any informed advice on this.

Thanks.

i have seen that effect once, i think it was on the lcd panel pcb.
probably loss of panel bias voltage, but i just swapped out the whole panel rather than messing with it.

Eh, "the whole panel"?

Do you mean the actual LCD panel or the driver board?  Any pointers as to where to get such for less than what a new TV would cost?

i mean the actual panel, i suspect the fault is on the small pcb on the rear that interfaces the flat connector to the actual glass.

Best case faulty T-CON board which should be exchangeable (check voltages, especially Vcom) or LCD panel itself.

I second T-CON, fixed a TV that remembered the channel logo's long after you switched channels.
