    Re: LG 47LC7DF-UB No video issue

    I can't find anything about this model on LG's website except one obscure page for the Taiwanese model. http://www.lg.com/tw/support-product/lg-47LC7D

    I cannot read Chinese so can't tell if there's a firmware link or similar on that page. Maybe a model such as 37LC7D or 42LC7D will have compatible firmware, but I wouldn't bet on it.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Unfortunately I can't read Chinese either. I may try to find an online translator. In the meantime, it seems like we have it narrowed down to the mainboard, would you agree? At some point it may be better for me to look into a replacement board for time's sake.

        Vinceroger69, thanks for the link. I will check the v chip firmware out.

          I have a similar problem. I changed out the caps on the PS. Now when I plug it in, the video cycles on and off. Off for a couple of seconds and then turns back on for a couple of seconds.

          Any Ideas?

          Thanks

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Assuming...

            Philips 75PFL5704/F7 A Video Issue
            by Nicktronic
            Hey everybody, got a strange one here.

            The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...

            Motherboard issue - all voltages OK but no display
            by gurj1979
            I've got a couple of Intel and AMD boards which turns on fine, all voltages at all coils are present, but there is no display.
            I guess this like Code 00 issue.
            I've tried a couple of good CPU's and working Graphics Card.
            PCH has been replaced too. On one Intel board I have even replaced the CPU Socket.
            The CPU's don't get hot, but gets a bit warm.
            All RAMs are good.
            BIOS is good on all.
            PSU is Antec 1000W and I use this for on more powerful boards and 2080Ti cards, so this isn't the issue.
            What's the issue when motherboards have this issue ?

            Insignia NS-LCD019-09 issue: Power light turns blue for 3 seconds, the flashes red before going solid read again
            by cajoeg
            Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.

            The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...
