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.

by iglitareHi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
by EazyBonePicked 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...10 Photos -
by howardc6449UJ6500 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... -
by JackUziHi 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...2 Photos - Loading...
