How to fix a screen warm up issue on an LG TV
• TV turns on w/ sound but screen is black. • Then as the TV continues to stay on and warms up, thin vertical color/rainbow lines appear w/ sound. • And finally the picture will appear w/ sound. And no further issues occur until we turn off the TV and it happens again when we turn it on after it being off for a while. Appreciate on advice on what may work to fix. Some info says T-con board may need replacing. If it is not the T-Con Board, can you please advise what part/s require replacement? Cheers John
