    I don't know why this question is under "Projection TVs". This is a flat-panel LCD television.

Hi, I want you to first unplug your TV and unplug the cable box (if you have one) and unhook the cable from the TV, wait 2 minutes. Starting with the cable going into the TV, rehook that first. Then restart your cable box (if applicable), then plug the TV power back in. Check the "Tuner Mode" control for the correct setting. Next, run the "Auto Program" feature to find all available channels, this can take up to 10 minutes. Once done with auto-program, press the AV button on the remote control and make sure the correct signal source is selected (Should correspond exactly with source where you hooked in the cable to the TV). If you are running in PC mode, the video signal must be present or the TV will turn off. If this does not fix the problem, please respond with the name of the cable/sat provider you are using as well as if you have other TVs available for other checks, are all cables free of breaks in the cable as well as all end fittings in order. and lastly if no cable box, is the cable directly coming from the wall to the tv.

    Please click on this link and follow the instructions.

    If this does not work then reset to the original factory settings by performing the following steps:

    1. Press the MENU button on the remote control to see the onscreen menu.

    2. Press the CURSOR DOWN button to highlight the INSTALL menu, then press CURSOR RIGHT to enter.

    3. Press the CURSOR DOWN button repeatedly to highlight the FACTORY RESET control, then press CURSOR RIGHT to enter.

    4. Press CURSOR DOWN to select “YES” to reset the original factory settings.

    5. Press the MENU button repeatedly to clear the menu from the screen.

    i want to let you know that lcd panels have a tube across the bottom
    that's called a cold-cathode fluorescent light (ccfl), and they do go
    bad. the ccfl provides backlight to the screen, which means if that
    were the problem you'd still be able to see something on the screen, it
    would just be very dim.

LC-23Y25 Problem with turning on power?

so i had the same problem. red light came on, but no blue light or anything on the screen. it turns out that there were some capaciters blown on the circuit power board. unless you have a good understanding of circuit boards, its not a quick fix. but for someone who knows their electronics, its not too hard, and its not expensive to fix, unless you bring it into a store. but the supplies needed arent expensive. good luck
