In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I bought philips model no. 47pfl7403d/27 in 2008 .Suddenly last month it started skipping picture but we could hear sound.After few days it started smelling like something is burning and it stopped...


Seal deal w/ ours. I took it apart and the power supply board had the burn marks on it. Just ordered another power supply board (pn: 272217100571) for ~ $100. TV back panel comes off fairly easily to get at boards.
