    LG 42LE59000 no picture or sound turns on ok

    Hi there I had a look for any other posts relating to this and couldn't find any so I thought I'd start one. I'm having an issue with the above LG it will turn on ok and do its fancy light show across the bezel but I get nothing on the screen, I can see its responding to the signals from the remote as the power light flashes, I get the same plus an audible when the buttons are pressed on the set. I've had a look at the boards visualy and all apear ok (I've added some pic's) has anybody got any experience with this isssue/set? Thanks in advance bad cappers :-)00

    It's an 42LE5900 not 9000 sorry.

    That looks just like mine which I had just tinkered with.
    Dont wanna say 'fixed' but nicholas1110 said his problem was the main bga processor and mmartell suggested to heat it up, which I did and it worked.
    Just used a regular hair blow dryer.
    Using it as a monitor to type this right now.

      So are we saying a reflow will (possably) fix this and if so does anybody know the temps I should be looking for? do you reflow all boards at the same temp? I would have though you would as solder is solder isn't it?

        Don't reflow anything.

        Firstly are the backlights on?

          nothing is coming on that I can see, I've read on another post that you can force it on for diag but I haven't done this (not sure how to) as I don't want to full kill it.

            Can you remove the wire thats labelled B-dim or P-dim something like that from the harness.

            Just remove that one wire.

              BTW don't just tug the wire out. It needs to be pressed in then in will just slide out.

                  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...

                  Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                  by Mgiffune
                  I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                  I ordered a supposedly ‘new' Tcon board this time, and

                  what i went through dealing with my mobo with dead onboard sound!
                  by ChaosLegionnaire
                  so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                  i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

                  Samsung QN75Q6DRA, No Picture, Has BL, and Sound
                  by Dodgethis
                  Hello all,

                  This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...

                  Samsung UN60F8000BFXZA ~ No Picture or Sound - 5 Res Light Blinks
                  by kca
                  Hello all ~

                  I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.

                  This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.

                  No picture. No sound.

                  I tested all the voltages coming out of the power supply...
