    LG 42LV4400 TV has sound but no picture

    Hello to all,
    I have an LG 42LV4400. The symptoms are as follows. The set turns on normally, red light when off - blue when powered up. The is no picture but the back light appears to be on. I'm able to see the various menus screens when i hit the home button on the remote and even the channel guide, I've got fios. Also, the audio seems to be working perfectly. I've removed the back of the set and I don't see anything obvious such as swollen caps etc.
    Any help is appreciated.

      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...

      Samsung TV`s UE32J5500AK and UE48H6400AK Red Standby Light - No Picture/Sound
      by slimsoul
      Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.

      I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.

      I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
      The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...

      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...

      Monitor Audio RSW12 - Green light, but no sound
      by MOSSEP
      Hi

      Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

      Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

      The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

      I have already tried replacing all of the...

      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
