    Lg 32LG3000 no picture

    Hi!
    I got this tv from a guy who said that before the tv showed vertical lines but now there is nothing on the screen.
    When the tv turns on led flashes 2 times,backlight flashes and turns off.
    I checked the voltages on psu and they seem ok, caps look ok too.
    I tested the fuse on t-con and thats ok too. The inverter board gets 24v so I think that its ok too,but not sure,what do you think?
    How to check the main board? What would be my next steps in troubleshooting this tv?
    Thanx!

            LG 32LG3000 TV, three red light flashes, then the backlight turns on, but no picture
            by ItepK
            Hello everyone! I've found this television, and I began troubleshooting it.

            First, the television kept rapidly power cycling. I've warmed up the capacitors with a hairdryer, and after 3 dimmed red blinks, the backlight turned on, then turned dim, and no picture was present on the screen.

            I believed that this was caused by a bad power supply producing insufficent power (I've measured 3.5v on the 5.2v rail), so I've blindly recapped the board.

            After the recapping, all the voltages stableized, however, the issue in the title still remains.

            I could...

            T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
            by Tr0ll
            Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

            The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

            Original T-con:
            Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

            First replacement T-con:

            I thought it might be t-con and ordered new t-con from china(supposedly tested)...

            SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
            by JJAAMM
            This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

            Problem
            TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

            Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
            by TR103
            Hi, I have a Samsung UE50TU with:
            - sound and backlight, but no picture
            - when it arrived, it had a picture for a few seconds
            - it keeps rebooting
            - without ribbon cable between the two panel boards, it does not reboot but I have no picture
            - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
            - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

            - without cable between mainboard and lcd panel and with a jumpered...

            55" Magnavox LED set flashes picture
            by Rmasters3
            When using a cable box with an HDMI connection, I turn the set on and a scene flashes on the display, but then goes to black. When I bring up the sets Menu, this will run for an hour as well as anything else. I have replaced the cable box with no effect. I'm getting ready to try a Blu-Ray player to see how that acts.

            Does anyone have thoughts? Thanks
