Hi,
I don't know if someone can help me, but I'm going to give it a try anyway! I made sure to look up my issue before posting, but I couldn't find any thread for this TV model. I should also mention that I never fixed a TV before, please bear with me!
My Toshiba 43LF621U19 REV. B started acting up lately. I tried looking up its "symptoms" online, but I can't seem to find anyone experiencing the same problem, which makes it hard to figure out if this can be fixed and/or which part(s) should be replaced.
The TV was purchased brand new in June 2019. Recently, the image started jumping around every two seconds. The image is fine for two seconds, then starts jumping for another two seconds, goes back to normal for two seconds, jumps again, etc. This normally happens after the TV is on for a while, but it also happens randomly. I can watch TV for an hour before it happens for 20-30 minutes, then it randomly stops and starts again a few hours later.
I posted a video of the issue on YouTube if anyone want to have a look: youtu.be/1HjH31_HVlw
The issue happens when opening the TV, in the “Start” menu, in the “Settings” menu and on any input (ex: DVD player, TV, Netflix). I closed and reopened the TV, restarted it from the settings, went back to factory settings, unplugged and plugged the power cable and unplugged and plugged the HDMI cable. The issue persists no matter what I do, which makes me believe a component is at fault.
From what I read so far, it could be related to the T-con board or its cables. However, since I can't find a video demonstrating the same behaviour, I'm not a 100% sure that's the problem.
I would rather try fixing it then creating additional waste. Thank you, any help would be appreciated!
