    Sharp LC-46E830U 1-1 Blink with no Picture or Audio

    Hi All!

    Recently, the power flickered at my mother's house and even though the TV wasn't on, it no longer powers up. When trying to turn it on, it has one "long" blink, (about a full second), followed by a short blink, (about half a second). I've been reading through these boards - including a similar situation in this thread - and was curious if anyone can shed any light. I've definitely a huge novice with this stuff but I have a multimeter and don't mind trying to get a learning lesson out of this.

    For what it's worth, a TV repairman, over the phone, mentioned it was the "main board" and didn't sound interested in taking the job. He said these are pretty disposable units. But the earlier thread referenced above points to a bad LED strip or something.

    Any thoughts? Help is very much appreciated.

      try the "forced reset"... something like volume up, channel down keys at the same time while plugging in (check / confirm the exact sequence by doing a search). should reset any errors and possibly light up thereafter if you are lucky.... some have been.

        Thanks guys! I'll head to my Mom's house this weekend to give this a go. I previously tried something like VOL+ and INPUT or something, but no luck. Should also mention the buttons on the TV are those touch buttons, (not the physical ones).

          Help troubleshooting an audio problem with an RCA SGT-250 CED Player
          by samson7point1@yahoo.com
          The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

          The player processes the audio signal using two different reference frequencies. The "R"...

          LG55UB850V no picture or audio, just flashing LED's help please?
          by IAmOrion
          Hi members, I came across this forum when searching a fault on my LG 55UB850V TV.
          Rather than hi-jack another members post/thread I thought I should start my own even though it's an almost identical issue.

          The thread I refer to can be found here:
          https://www.badcaps.net/forum/troubl...-s-help-please

          My boards are the same, and my issue it the same. I have NO Picture and NO Sound. Nothing. When first turning on the TV at the...

          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...

          Vizio D55x-g1 (55" 4K, no backlight, has Audio and picture)
          by WayOfTheRoad
          Hello, everyone. A neighbor was throwing this TV away for "not turning on" so I asked for it and they gave it to me for free since Vizio gave them a new TV under warranty.

          I'm pretty proficient with electronics in general but this is the first TV I've ever tried to fix. I strongly suspect bad LED lights but figured I'd post some info and see if those of you more experienced with TVs can confirm my suspicion before I move forward. Some photos and measurements below:

          The power supply only has two outputs, one output cable going to the main board and the other...
