Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.
I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models. I have the 40-40pin cable that was used for the models with touch but do not need touch capability, was just looking for a better quality screen and higher refresh to actually...10-02-2024, 04:54 PM -
Symptoms:- From cold power-on, picture is perfect.
- After ~2–3 minutes, the image slowly degrades:
- contrast collapses
- colors wash out / look incorrect (greens especially bad)
- image looks “milky” / flat
- Turning the TV off for a few minutes fully resets it; behavior repeats almost exactly each time.
- Internal apps (YouTube, etc.) degrade the same way as HDMI input.
- On-screen display (menus) often looks mostly normal compared to the video underneath although its hard to tell.
I tried heating different areas with a hair dryer and I've isolated a specific area on one of the panel...01-09-2026, 02:20 PM -
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... -
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 -
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....
