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,,,

I need the outer screen for my Samsung HC-P4752W. Mine has a red line that seems burnt into it. Where can I get one?


It sounds like the RED CRT is cracked which will cause a red line. You can verify by looking into the lens of the Red CRT with a flasnlight if you see a line the CRT needs replacement. If no line then chances are the Convergence IC may have a problem.

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
