hi wendy, I have the same model tv and it has been doing exactly the same problem you have ever since buying it (2007 - 08) and every time it does freeze it seems to be on channel 9. The only way i overcome this problem is to turn the tv off at the wall for atleast an hour and turn it back on and it seems to re-set itself or should i say the built in set top box re-sets itself and it works fine for a few months and bang it does it again. Apparently there is a LG software update but only technicians can install this. Anyway thats my story! :)
Buffer boards or Y-SUS main needs to be replaced. What do you mean by motherboard? The power supply board or the Logic or X main.... They YBU/YBL and the YSUS work in unison. Y-Buffer upper controls top half, Y Buffer lower control bottom have YSUS controls both of those. There is also D, G, E F boards that can split screan. But they to are controlled with the Y-SUS Main. Hope this helps...
U have cable,some kind of pay tv?Tries unplug the cable box,replug the box for reset or to update new solfware for the box.If u have free air tv,get better antena like out side door antena or a digital antena.Also should change the batteries in ur remote and clean the IR lights both remote and tv make sure no blocking path to signal.
If it does this on all channels then the video on your AV out from the TV is bad.
If it only happens with some channels then this is Macrovision protection working which will not allow you to record premium channels and any that are using this protection.
