[Solved] Sharp LC-48CFE4042E - Dealing with Color Distortion: Matrix Type Options and Possible Fixes

Top Serwis 11985 9
Best answers LABEL_AI_GENERATED

How can I fix the color distortion on a Sharp LC-48CFE4042E, and what panel/matrix type is installed in it?

Use the LSC480HN08-G01 panel; it has the T-CON integrated into the matrix itself [#16604942] [#16606233] The symptoms were suspected to be a gamma/VCOM-type fault, similar to old AS15-related issues, but no service-menu or local-keyboard trick fixed the unchanged screen [#16846303] [#16845409] A USB firmware update even pushed the set into an autonomous color-pattern/heating mode, but that still did not solve the distortion [#16672191] In the end, replacing the main board healed the TV [#17092929]

    Symptom as matrix type options shown. Everything in the picture is afraid that you will need a batch to sleep the matrix.

    Recently I uploaded via usb soft from Sharp's website. The effect is that the matrix has entered the heating / autonomous mode, colorful charts appear periodically.
    How to get out of this oppression now?

    I read the memory content of this matrix, the memory is empty FF itself.
    Probably it is supposed to be so, checked in a different matrix.
    Maybe someone knows how to turn off the `` heating '' mode on this TV?
    It can be for a fee.

    Hello.
    In Samsung, you just need to press the local keyboard.
    Maybe it's similar here?

    You can see that it responds to the local keyboard but the screen remains unchanged.

    It looks like something with "gamma"
    * resembles the problems with AS15 (Gamma and VCOM Voitage) described long ago
