Samsung HC-P4752W Blurry ONLY on HD Channels

My Samsung HC-P4752W 47 inch tv is blurry only when I veiw the HD channels. When I am viewing regular channels it looks normal. It seems that every time I view 1080I channels that the test is blurry and it is a jerk of a problem. I changed out cable boxes, HD cables, and I still have the same issues. I even tried different HD ports on my TV and still the same result. Any Help would be great here. Does this sound like a convergence board?

    I came home from vacation and I had lines on all the channels. I called the cable company and it straightened out the regular channels, but not the HD channels. The Blue Ray and Surround Sound also are not working. Is this a problem with the board and/or inputs?

Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,

Blurry picture when hooked up to direct tv.Why?

try lowering the sharpness on your tv, because if the sharpness is to high it will make NonHD objects look blurry, also try changing the input cable or type of input.

Try it again in the original room where the TV once was. If the channels from 47 and up are back to normal, its a cable signal issue that the cable company must resolve. Its possible that the installer may have driven a staple thru the coaxial cable or did not correctly attach the fittings.

I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs
