Tv turns on and then goes fuzzy and cracking sound from it takes about 5 mins to eventually sort it’s self out and my right speaker is crackling
@craigtaylor all of this sounds like an issue with the main board. Let us know what model this is so we can at least try to help you further. Also let us know what you have tried. Update (09/11/2019) you would have to post a good image of your boards with your question. the audio IC’s on your TV are listed as IC1202 and IC1203 To test those you pretty much need to have an oscilloscope. The only thing you can check with a multimeter is IC1202 which is a SGTV5810 audio processor. So, post some pictures of your boards and let’s see. Of course try to connect a headset and see if that plays the sound properly. Also, clarify the “then goes fuzzy “ part. Check your speakers to make sure that those are working properly.
