SOURCE: I have a Samsung Plasma 4252 and i have red horizontal lines.

I have the same problem on my set. I had a repair technician out today and they wanted to replace the circuit board that the buffers are connected to and the adjacent board that drives the buffers. If you remove the back panel the buffers that are in line with the distorted areas on the screen are running super hot. Estimated price with labor was $700.

SOURCE: Our LN40A630 has three horizontal white lines

This is a sign of your LCD panel beginning to die. Sometime soon those lines won't fade away and will become permanent parts of your TV screen.

Considering the fact that your TV is approx 3-4 years old, this is normally the expected lifespan of a TV. Once the TV becomes unwatchable, your best bet would be to begin shopping for a new one.

Makes a clicking noise from the fuss box under the hood.and wont do anything when trying to start it


I just had this problem and it got really BAD. it would start clicking along with the light flickering with the clicking sound. then while driving it would stall out and get real slugged. So this is what i found to be the problem. if you look at your battey you need to take off the negative side. clean it up really good. then when you put it back on, make sure you have it all the way down and real snug on there.. then make sure the other connections that are there on the negative side all also tight. start it up and drive it around.. that should clear it up. while you at it clean pos side as well just in case.. I also bought a new fuse for underneath as well from ford. its called multi function fuse. looking from underneath its the big black one in the middle on top of your fuse bank under dash.

this is also the negative part i was talking about, and all the wires that are connected to it to make sure is tight aswell

LCD TV lines


The shop is in business to make money so no free fix--Someone with a good eye who opens the set may see where the water went and then Google the model for a list of boards......several dealers (not Vizio) stock and sell all or most boards in the newer sets.
