crazy 0 Report post Posted June 9, 2022 Hello hello, I was wondering if anyone could help. A samsung plasma tv was having problems, no image but backlights and sound on, so i replaced the TCON board. But now the new TCON board as soon as i turned the aTV on it made a buzzing sound. It has image now, but it's always flickering and the board always making noise. So now I'm uncertain if the problem is that the board is bad, or it may be something else. For reference, when the old TCON board worked, the image was good and no noise. Now with the new one buzzing sound and flickering, like the side panels aren't turning on. Weird. The voltages all seem ok, a little bit high but i reckon it's fine. Thanks for reading, and if you can help, that'd be great! Share this post Link to post Share on other sites

Part number, revision, firmware - everything must match, only in this case there is a chance to get a working TV. Recently, we also encountered such a problem, we tried several boards, but only one came up, which was completely identical to the old one, but fully working. I'm not an expert to say that this is the problem, but there is such a possibility. Share this post Link to post Share on other sites
