Question about Samsung HP-S4253 Television
On a 2-yr old Samsung HP-S4253 42" plasma, the screen is completely filling with small multicolored pixels and no image, whether from cable box, dvd, or just on without other source. Can you give me some potential causes and approx $ before I have a $150 pickup and diagnostic repair call? I have unplugged and re-plugged to see if there is a re-set but no help.
The pink fuzzies come from a faulty Ymain. If you are looking at the set with the back off, its the largest board on the left side. Get the part number from the board and replace that one first. You may have to check the buffers or the logic board if this doesn't solve the problem but 9 times out of 10 when the picture is firing random pixels, its due to an overload in the Ymain (also called the YSUS).

I had the same problem. Luckilly I had an extended warranty. Repair tech said it blew three main boards inside and to fix it out of pocket would have been more than the screen was worth. Hope this helps.
