    Philips 49PUS6401 yellow smudges after lens repair

    This tv has a TPT490U2 panel which I guess is probably also in a few other Vestel things.

    I had the LG type problem of a couple of bright spots so disassembled the panel and found several detached lenses, as expected. All the LEDs were fine though.

    Now having reassembled the panel, the bright white spots have gone, but there are sort of diffuse yellowish "smudges" on the display. These correspond to the led locations and range from not really visible on a dark background, to fairly noticeable on a plain white background.

    Is this likely the be the type of glue I used for the lenses? Or did I reassemble the panel incorrectly?
    The glue I used was a generic acrylic glue that claimed to be transparent.

    Just considering whether to try again with the correct glue or just live with it.

          Ok, I did have suspicions it was the glue so thanks for confirming that.

          I have some of the correct glue on the way, but I guess it depends how successfully I can remove the glue I have already used.

          My fault for being in a rush and just using what I had to hand. At least it was educational.

              Philips 37pfl560: Yellow picture
              by madyoyo
              HI.

              I have a weird problem with an old Philips 37pfl560 TV i put out of storage: the picture have a noticeable yellow hue, and its not caused by the settings (did a factory reset). I've never seen this before. I will try to get a photo with a real camera, with my phone its hard to see because of automatic white balance, but in real live the whites are really yellow.

              Anyone have an idea of what can cause this? Can CCFL tubes get "warmer" with time? This tv have several analog inputs,so its nice for retrogaming....

              Philips 8200 series 65PUS8204/12 stuck at Philips Logo
              by G33RT
              Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

              It does power up when pressing the power button.

              I already try the power button while plugin the plug with no result.
              Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

              Could this be an PSU or eMMC issue ?

              Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
              by acedogblast
              This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

              There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

              Philips curling iron - is this a common AC cable?
              by double_DD
              Hi all,

              Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
              As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.

              Not sure if this is something Philips proprietary, or a standard, but the cable plug...

              Philips 47PFS7509/12 LCD TV problem
              by janos6662000
              Hi

              I have here a Philips 47PFS7509/12 LCD TV which came to me with a weird problem : without signal i could access menu, make a factory reset, access menus, etc.
              When i applied cable signal to check image, i had normal picture, but TV was restarting.
              I downloaded original firmware and applied the update, but the problem remained.
              From a colleague i received a "factory package software" which is a lot bigger.
              I made another firmware update, but still did not solve the problem.
              Somewhere on the way the error got worse, because at the moment the...
