    Vizio VP50HDTV10A Plasma TV Issue

    So, I'm having a bit of an issue here with a television set -- it's one I haven't encountered before. The original issue was the famous 'Bad YSUS' these are known for. So, replaced both buffer boards and the YSUS. TV worked great for 20 minutes, then a thin (1/2" - 1") part of the screen started acting weird. I say weird because, when there is composite/RCA (yellow/red/white) input, it shows up as a blue vertical line. When the inputs are being switched or there is no signal, it shows up as a part of the OSD not working and black. When you go to the TV selection, the 'snow' shows perfectly fine with no issues (did not try to tune into a station, though). Please see the attached pics for more details.

    I'm wondering if one of the address buffers (XL/XC/XR) needs to be replaced maybe? Thanks for any advice you can provide on this; I find it very weird that the snow shows clear, and I can't see it being a bad panel as the part is not just 'dead', it -can- be addressed; as seen by the snow (at least that's what I make of it).

    Also, some notes on the pictures. The text 'shadow' is just because of the extreme angle of the picture. Also, the 'discolored' look in the snow is just because of the camera, it is not there in real life. Note in the text how some of the 'writing' is missing, though; it corresponds perfectly with the solid colored bar when watching a DVD through the RCA input.

      Well, I solved my own issue. I took the heatsinks off the XL/XC/XR boards, disconnected all the ribbon cables, alcohol swabbed them, and reinstalled. Problem is fixed. Hope this at least helps someone else in the future.

              Vizio m601d-a3 backlight issue
              by Mectronik
              Hello, I'm working on a Vizio m601d-a3 with a backlight issue that I am having a difficulty diagnosing it. As it sits, the tv powers on, displays the Vizio symbol and with nothing hooked up it will then display no signal but you can only see half of the screen. I know it's a back light issue because the picture is there without light behind it, as I can see it by doing a light test. I've taken off the paneling and done a visual inspection. If I disconnect the tcon ribbon cable to the affected side then the entire half of the screen goes away. I've checked voltages at the LED driver from the main...

              Vizio P759-G1, Tcon issue?
              by EazyBone
              Got this TV free. Guy said it tries to turn on and doesn't. I haven't seen this specific issue before but shown in video. Any way to test the screen to rule it out on these Vizio? Or anyone seen this issue before?

              Any help appreciated

              Vizio E65-E1 strange image issue
              by remmurdmd
              Hi everyone. First new thread here. I picked up a TV on the side of the road. It appears to function correctly with the exception of an image issue I'm unable to describe. I've searched for “double picture” and “double image” all over the web and all I get is repair videos for when the picture is blurry and the connections are getting interference between the display panels and the t-con board. I believe this is a t-con board issue, but I haven't found anything telling me conclusively that this is where my issue is. I'd appreciate any assistance you can provide. I live a pretty busy life...

              Issue with 42 Vizio TV
              by derrickcaputo
              Hello,
              I have a 42" Vizio TV. I hooked my tablet to the HDMI inputs. Everything was fine until the screen went black and now the only input that works on the TV is coax. No hdmi, no component, no rca. I tried hooking up a laptop to the Hdmi port and the computer
              detected the TV model but no image.

              Is there anyone having the same issue? Did you find any solution?

              Interesting E60-E3 (Vizio) issue
              by bscottjohnston
              Good morning BadCappers,

              I picked up a Vizio E60-E3 yesterday. The donator claimed that it never powered on and that he checked Voltages at the power supply. I checked a handful of Voltages and then laughed when I realized I was trying to turn it on via the menu button on the back of the TV when its upside down on my TV repair bed (literally my guest bedroom).

              Okay so I took out the mainboard and decided to flux up the BGA and heat it up. Upon reinstall of the mainboard the TV does indeed power up but all of the screens have a blue hue AND the video displayed fails...
