I have a samsung LA32s71b tv that 3 months ago had to have the sound board chip replaced by tisco as it failed(only 7 months old).
since its been back my daughter and i notice that the picture goes from very bright to dull in a flicker and then back again.

also when i power the tv up it can take up to 5 minutes for the picture to become bright.the first minute it is very dark.
when watching the credits to a program its flickers almost strobe like.
im on telstra digital in wellington.
does this sound like i have major problems or is this what people mean in regards to blacks and dark colours not being very good on
LCD.
