The complaint of this Konka 32 LED TV was auto RGB color change the moment you turned on this set. There was no channels, no sound, no picture but just changing (rotation of colour) plain colour of Red, Green and Blue that  covered the whole screen. If this problem happens in the LCD Monitor when connected to the computer CPU, you can suspect either the horizontal or vertical sync wire broken inside the VGA cable.




 

But when this kind of problem happened in LED TV then it would be different story.

This kind of problem is usually related to the TV firmware and to solve this problem one needs to know how to enter into the factory service mode and reset the TV to default. You need the service manual in order to do the job.




Since I have solved this problem couple of times  thus I do not need the service manual to guide me how to reset. In this article I’m revealing the secret how you can reset it easily especially for this Konka LED TV.

First, turn on the TV until you could see the auto changing of the RGB color in screen then point forward your TV remote control and press (and hold) the “Mute” button for 10 seconds. After that the TV will automatically revert to default setting and once done the normal picture will appear again as seen in the next photo.

Conclusion- If it can’t be reset this means you may have to use a programmer to  program onto the faulty memory IC. If you wish to become a good TV repairer and do not want too much theories, you can check out Kent’s ebook on LCD/LED/OLED TV Repair HERE.

    Good job and indeed an easy fix. We do not know any electronics with the name Konka in my country. But I agree that Kent writes very useful e-books. Especially the extra's that he adds to his books as download content. European tv sets are sadly hard to find in any of them. But since Samsung also makes bad tv sets that do not have any service documentation to help, Kent's books are the best way to start.

        Understood Humberto. Brandnames like for instance AudioSonic were more common in my country. And I guess almost all Brands are assembled in China.

    Thank you for your wonderful article. Does this mean the customer entered the mode by mistake?
    If not what can cause this problem like a powersurge?
    Will the problem return do you think so you have to replace the faulty memory IC?

    Thank you
