You seem to have what is called error diffusion. Either call samsung about it and arange service or do it on samsung.com. What kind of warranty do you have? Depending on your date of purchase you might be able to get samsung to help cover it or pay for it all.

SOURCE: Samsung LCD TV LA40S81.... Turn on

Hello
It is due to the power regulator section of your TV. If DC voltage come to T'con board and other circuit board won't have enogh regulated and smoothed current this type of fault will occur. Open your Tv and check for any bulged capacitors on the mains power regulator board. If there, repalce it with same type and capacity. I hereby attaches a picture, of an other set's power supply board with bulged capacitors to give you an idea about how a damaged and bulged capacitor will look like. Check this, If you want anymore assistance from me, feel free to get me by Fixya.

gopakumarg43_41.jpg Note the top of the red arrow marked capacitors. They are damaged. A ggod one will look like one you can see on the top right with flat top surface.

SOURCE: screen has started to flicker constantly. tv is

Same here. TV back-light would flicker occasionally. Sometimes it would stop and other times it would not. This is the only TV I purchased with a warranty (because I bought it online and got a great deal). The Samsung repairman came out and changed out the circuit board that has the power supplies for the back-light. Total time was 10 minutes to fix. Apparently this is a known problem with some of their TV's. He said the vendor for the power supply transformers had issues and they have since changed vendors. The flickering is caused by one of the transformers failing (it has 2 to power the back-light).

*NOTE: even if your TV is not under warranty call Samsung directly. They should still do the repair for free according to the repairman. Just tell them that you have seen postings on the internet about this problem.

General Alignment Instruction
1. Usually, a color LCD-TV needs only slight touch-up adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync.
2. Use the specified test equipment or its equivalent.
3. Correct impedance matching is essential.
4. Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test result.
5. Connect the TV only to an AC power source with voltage and frequency as specified on the back cover nameplate.
6. Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts.
7. To protect against shock hazard, use an isolation transformer.

Samsung HDTV model HLR5067W screen flickers when some commercials play other commercials are ok when viewing. Could this be my HD set top box or a cable?


If the TV works well with your dvd and regular programs there are no issues and the flickers due to commercials can be due to excess signal strength or even poor control from the set top box.
Try with another set top box to confirm as some of them can process noise which can cause this issue.

Screen has started to flicker constantly. tv is 9 months old. When switched off flickering stops for about 5-10 minutes and then starts again


I had the same issue occur on my ln55c650 and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.
