    Snow with digital TV signal?

    I partially plug in an HDMI cable into my Toshiba 32AV502U LCD TV (has been used for 10,000 hours) and see snow on the screen with an otherwise stable picture, and I mean the kind of snow typical of weak off-the-air analog broadcast TV signals from an antenna, complete with the snow moving around instead of being stationary, only the picture isn't nearly as white. The picture clears up after I push in the plug harder and wiggle around the connector a bit. The same thing happened a couple of times when I tried another HDMI cable (generic but a different make) and the TV's other HDMI input and also with a different Toshiba (26AV502R, slightly newer series, under 1,000 hours use). I think the snow consisted of white dots, but I don't remember what the sound was like in any of these cases.

    I couldn't reproduce the snow with the composite, RGB, or VGA inputs, and I don't have a source for hi-color (or whatever those other analog inputs with 3 coax cables is called).

    Aren't weak digital signals into HDMI supposed to make the picture break up into little squares or horizontal bars or show still images, rather than produce snow?

      I've seen a Blu-Ray player display snow with a slight colouration briefly; probably an effect of HDCP negotiation.
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

        I need an answer to how to amplify my WiFi signal because it is so weak outside
        by sam_sam_sam
        I have a really bad situation right with a very weak WiFi signal outside of the house and I have been told that I can not have two routers on my modem because it cause issues so what is the solution for this issue

        I can fix the garage door opener with a cat5 cable to device modem or at least that is what I call it and it works very well so far but by doing this I have no router in the garage and no WiFi signal inside the garage unless the door is open but it is extremely weak if not at all

        LG 55sk8000 plb ..snow in the middle of screen but can see that picture exists there
        by burbutsalos
        Hello everyone.

        I have this TV set which has this issue. It shows a vertical bar im the middle of the screen.
        The panel has 12 cofs and the problem seems to be on the territory of the first cof on the right side.
        The tv fires up and you can see a good picture exept that vertical part where multicoloured pixels exist.
        The strange thing there is that you can see behind that snow that it shows picture but as if there are these pixels in front so you cannot see clearly.

        The effect is there even on a completely black screen.

        The screen...

        Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
        by AstutePauciloquent
        Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

        I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

        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...
