Hello, I nave a TV ad in the object; when i turn on it there are only coloured orizontal lines then, after a lot of minutes, the immagine starts to come from the upper part of the screen.. After 30 minutes there is a full image but it is glitching or flickering. Thanks for any help. S. Update (12/30/2017) Hello, thanks for the answer; i have changed almost all the capacitors of the powerboard..Also if they seem in good condition.. I will make some pictures of the TV..thanks!
First image at 30 seconds after the switch on.. Second one after 30 minutes.. Thanks!
@stewecar post a few images of what your TV displays. If it clears up after a while then it is usually caused by bad capacitors. If you can, remove the back of your TV and post some good images of your boards with your question as well. Use this guide Adding images to an existing question for that. Right now it sounds like either a bad main board or bad t-con board. Update (12/31/2017) Those lines do not originate from the power board.. This looks like an issue with the Gate Driver on your panel….
