<\/p>\n\n\n\nSo… I\u2019m trying to fix my Dad\u2019s Sony 3D TV (KDL-50W800C) and I\u2019m running into trouble! I figured it’s easier to share a post like this with images rather than upload photos to multiple places, etc.<\/p>\n\n\n\n
A few weeks ago suddenly his TV started displaying vertical blooming bars of colors. He sent me a short video clip, here are the photos from that clip. The sound was playing perfectly and he could still make out the info banner (saying the input label etc) for a while. The lights would move and change, turning the set on and off didn\u2019t help. Eventually the screen went dark and nothing would appear, but the sound still worked.<\/p>\n\n\n\n

So I carefully ordered a new T-CON and main board, checking the stickers carefully to ensure they were a perfect match. I tried the T-CON board this past weekend, but after installing it there was no change.<\/p>\n\n\n\n Currently the TV turns on, the backlights turn on, but the only sign of life is the sound on the screen, the backlight, and a dozen or so dots on the bottom corner of the display. It\u2019s almost as if it\u2019s a pressure point or dead pixels\u2026 but the TV wasn\u2019t handled until I arrived to inspect it. Today a new main board arrived and I followed the instructions to flash it, although the indicator light colors never turned to the colors the instructions stated (amber \/ green), it did seem to eventually successfully flash the board. Sadly, there\u2019s no change in what\u2019s going on, the screen is still black with the dots in the corner. I wouldn\u2019t have invested much into this, but it\u2019s a 3D TV that he loves and I figured since they don\u2019t make them anymore, it was worth a shot.<\/p>\n\n\n\n Has anyone here had any experience with these symptoms? I haven\u2019t checked the power supply with my multimeter yet, but since the lights and set come on and stay on, I\u2019d assume that wouldn\u2019t be the issue. -Steve<\/p>\n","protected":false},"excerpt":{"rendered":" So… I\u2019m trying to fix my Dad\u2019s Sony 3D TV (KDL-50W800C) and I\u2019m running into trouble!

What I’ve tried…<\/strong><\/p>\n\n\n\n![\"\"](\"https:\/\/mac84.net\/web\/wp-content\/uploads\/2023\/03\/FsBgwJNXgAEAl8R.jpg\")
<\/p>\n\n\n\n
Any thoughts?<\/strong><\/p>\n\n\n\n
Also, I would assume the panel isn’t bad but… maybe that’s a thing? It certainly seems like I guess that could be the issue… I just don’t know much about these things.
Thanks!<\/p>\n\n\n\n
