Re: Panasonic tc-p42c2 to tc-p42c2 panel swap?
Sounds like SS board failure on that one.
Only way it could work is if SC, SU, SD and SS are all the same which is probably not the case as they are different model years (2009 and 2010 I believe.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

65x900h with the panel from a 65x930d.
900H: model yr 2020, Samsung panel
930D: model yr 2016, Innolux panel
spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.
the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...07-11-2023, 11:11 AM -
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... -
TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.
tcon is built into mainboard.
Only one cable goes to panel boards.
there is a cable from one panel board to the other that links them.
cost cutting measure that results in us having harder time to diagnose.
removing the link to the second panel board allows TV to stay on with stable backlight but no image.
used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board.... -
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 -
Hi
The TV seem to start ( blinking green) but goes into blinking red. No display and or backlight. Full view photo.
Actions :
1. Disconnected Panel's Right, 2nd, board : TV comes ON (steady green , no blinking red )
1a. You can see in two photos the B/W screen , fading blue "HDMI12" , and the wierd sides of the image, like an old CRT.
Obviously the fault is from or on the Right, secondary board
2. I taped the Flex tracks, ~2 tracks at a time- see Photo. The issue seems to be on the V lines (Assuming Data...09-03-2023, 03:51 AM
