How do I fix pixelation on my Samsung LCD Flatscreen TV?


Hello!
Looks like pixels are appearing due to the failure of TV's main board. There is no "reset" button at all. the problem occurs due to fatigue failure of solder joints under main board's microprocessor. Technology has changed, but not in our favor! At computer motherboards, there is "zero insertion force" plug, which connects "micro" to the main(mother) board. It allows I.C. chip to be well connected to the circuitry, despite the difference in ambient temperature. Latter makes of TV's main boards using laser soldering of 100+ contacts to flat board via led-free solder alloy. after numerous cold/hot/cold cycles, the alloy becomes brittle and fails to connect all the pins of "giga chip" to the board. Plus: there is no such thing as a cooling fan or, even basic heat sink in most brands. "Disposal" technology! The only way to cure the problem is to replace main(signal) board, if your set is less than 3 years old. If more, there is a possibility of bad capacitors in a power supply. If the set hesitates to start up cold, that's the issue. But...? Couple month ago I did replace main board in 46" Samsung LCD Panel, due to the same reason. Looks like you are up to repair your set. whether it's a panel or D.L.P. the problem is beyond "reset"! It will only get worse over the time. Call for service or give me your model#. I might help you with part search and replacement procedure.
Thanks,
Alex.

Over time, my 2007 Samsung LCD TV, model LNT4665F has developed random vertical pixel noise lines scattered throughout the screen. What could be causing this?


This TV is known for powersupply failures and this can be effecting the incoming voltages into the mainboard (AKA tuner board). This would cause the noise. Please have someone look into the powersupply and check that the proper voltages are coming from it. If they check out ok, you need to replace your mainboard.



Please rate if this helped :)

Blank sp;ot come over the left side of the TV


That is a failure of the pixels - either because the screen has been damaged in that zone (someone hit it there) or (in case the spot has a regular form) the buffer circuits commanding the pixels have ceased to work.
In the first case the tv is dead, you can't replace the screen and not pay more than a new tv for it.
In the second case the buffer board corresponding to that zone of the screen will have to be replaced - it will cost you about $175.

I have a ln-s3238d that i got a couple years ago. Last month it started getting a line of pixels running across the top of the screen. over the last month that problem has gron to four lines on top and...


Hi andrew, its not a big problem.. Decent TV. but the pixels are DEAD. that means you have to recover them by fixing the LCD. this would cost you around £40-60 for a 32 inch TV. hope this helps!

All ABC Channels pixelate in evening only.


You are possibly very close to the truth when you say someone has thrown a switch.

Take a look around outside, what starts to operate between those hours of the evening close by? Any amateuradio antennas close by? Workshops or night welding shops/neighbors etc? See if any of your neighbors also have similar problems, although you may be in better line of sight, so get the worst of it.

Can I see the difference


Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.
