Was sent pics of this Sammy so not sure of model # yet? Its ghosting the picture. Everything else works great. What should I be looking at boys?? Tcon?? Or bad panel?

Re: Sammy LCD ghosting. Is this a bad panel?
Does the picture get better if you gently try and twist the tv frame or press at the top of the tv because it might be bad tab bonds -
Re: Sammy LCD ghosting. Is this a bad panel?
Not sure as the tv isn't in my possession yet. They just sent me that picture and wanted to know if it's saveable? Other then a bad tcon or LVD cable?? Will have to see when I get itComment

I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.
There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

Picked up this Samsung above thinking it'd be backlights but it isn't. Now MAYBE I'll get lucky.
Found some shorted caps among the panel boards. Each cap along the line is shorted. On every board (3 panel driver boards)I disconnect each side right and left ribbons and they are no longer shorted caps and have about 1.5Mohm resistance (on left and right boards). The middle board has the main board disconnected and the caps are shorted. Last 4 pics show arrow to caps.
Now what exactly do I need to do in order to attempt to fix this issue?
do I have to take each one... -
49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on... -
Hi all,
First post so please bear with
So I found a similar issue on another thread but have been advised to open a new one so here it is.
One day this TV started doing this:

This happens on all inputs and menu screens.
Thank you to nomoresonys for previous advice - to check voltage on powerboard connector and possible loose/bad tab bond.
I've opened it up and tried reseating all the ribbon connections but the problem remains. I need some support in testing... -
Like the title says , this is a very interesting problem , never experienced this before so i thought i'd share and maybe get some help on this. So the problem is as such: TV comes on , some gibberish flashes on screen and the screen remains black , the owner of tv said he heard sound. Now i checked some things cleaned all connections first of all so i dont run in a circle. Then i disconnected one of the cables for the panel , and viola, the left side of screen comes on, then i tried to switch it , with left side disconnected and right connected. Same problem persists. I checked some voltages...
