    42pfl7422d/37 sound and blue screen

    Hi all,
    I have serviced electronics since the early 70's but never one of these. This unit has good sound and backlight but only a bright blue screen. I did have it start working and worked perfectly for about 24 hours. I shut it off for a day. When it turned back on it was back to a blue screen. Anyone seen this before?
    I tried replacing the main pc board with the tuner and hdmi connectors on it with a used one but this board did not even give me sound. Now it is possible that this board is on an hdmi setting but with out the menu i can't verify.
    Any comments welcomed
    Thank you
    Gary

      Samsung TU8000, backlight and sound on, stuck in blue screen
      by mar1in
      Hi everyone,

      I've got this Samsung here that would be stuck in a boot loop.
      After opening up and doing the tape block method, I was able to get it to turn on and play sound from the HDMI input, but with a blue screen.

      Does that mean there is another combination of pins that I need to block in order to get a picture, or is there something more serious, faulty mainboard or faulty panel?

      Thanks in advance

      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
      by Ryan.man
      Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

      My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

      This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

      70LE660U dark cloud or black screen with sound.
      by Rozp
      Hello Everyone,

      This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.

      I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area....

      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      ...

      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...
