Have you got time for a light heating of the tcon? Not a real reflow.. BETTER TO DO IT when tcon is on the turned on tv, so you can view the improvements.. patient a bit more if possible! 10 min. test..

Hi Davi, sorry slow response, the tcon is incorporated into the main board (all I'm one board). Thanks, I had originally tried everything I could including heating the board up with a hair dryer bit didn't help, thanks for the suggestion. The TV has gone back to the customer already. Thanks, have a great day.Comment

Some new tvs have an LCD screen attached to the outside of the frame with foam tape. These are "edge to edge" as they are called. I am trying to figure out how to reattach an LCD panel back up to the frame. The manufacturer used 3/16 inch foam tape along the top and rh/lh edges. I used a razor blade to separate the panel from the metal frame. The metal frame that the panel is taped to is 1/4 inch wide along the 2 sides and top. I completely removed the residue from the metal frame. There is some residue on the panel itself along the 3 edges, I removed almost all of it using alcohol and... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.
I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.
I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.
the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....01-13-2024, 01:57 PM -
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.

I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).
When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.
Later I checked for shorts on the panel PCB boards but could not find anything.
When I took a look with the FLIR i noticed the 2 resistors...08-10-2024, 08:39 AM
