checked your digital video board

check for "puffy" capacitors in the power supply 1000uf.

I had this same problem and one of my component cables was slightly unseated. Slight push back in and got all my wonderful blues back!! Thanks tvtek for this suggestion!

The Main bd has possibly failed along with P-Logic bd. Have a trained Samsung tech troubleshoot the set.

This change the voltage doesn't sound right to me. You What voltage is someone telling you to change ? You should just have to plug into the wall and turn on and get a nice picture. I think something inside has failed and that is why you have the snow.
Sounds funny to me, I would have a technician look at it.

I had the same problem with my S4253 using Directv. I then turned off the Dolby Digital on the sound settings on the Directv satellite box. Problem went away.

I have the same problem -- had a Best Buy technician out 4 times so far, replaced 2 parts, adjusted the voltage, etc., but still have the same problem -- looks like there may be no solution other than replacing the TV, which is an expensive proposition considering that mine is about 18 months old.

You would need to have a technician remove the back of the TV and make the adjustment. There are 2 small adjusters that they change to adjust the voltage.

Its the broadcasting company and there "new technology" Have had an over the air box to get local HD channels and lost my PBS station, turned out to be a new signal incompatibility. The same is with my HP-S4253. Must not have the latest SW to process the new signals
