My TV has a severe flicker/jitter in the bottom left quadrant of the screen. How do I fix it?
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Not sure if this will help, but most caps fail with the in rush of power, over and over. Sounds like they were not made right. You might try a UPS ( uninterrupted Power Supply) this may help you with dirty power from your power company. And with high spikes. Make sure you get one that will handle the TV current draw. As far as upping the CAPs keep the same or slightly high voltage and increase in uf. You might find one that has the same uf and a higher voltage rating that will handle it.

Samsung model LNT5271f excessive relay cycling before full power
Howdy,
Yes, it is very easy to repair. Solder iron wattage should be at least 300 w.
The PSB is the center Board (towards left) after you remove the back off the TV. Remove the shield that covers the Boards and remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Good Luck, big IRISH.

I have a Samsung LCD (LN-T5271F) about 2 years old
Call Samung customer service, they are doing this repair for free. I had the same problem at 11 months, they replaced the power supply board under warranty. At 2 years I had the exact same problem again and this time they replaced 2 - 50 cent capacitors on the power supply board. It took the repair man less than an hour and he had the replacement capacitors on hand. The original board and the replacement board they gave me had capacitors that were faulty. Hopefully these new capacitors will last. I have to say that I was thinking (no more samsung products for me) but I got excellent customer service and they admit that they had a faulty product and they accepted responsibility.

When I first turn the
you have bad capacitors in the power supply.
unplug the TV and take the back off.
there are two circuit boards in the center of the set, they may or may not be covered by a big metal cover, if they are simply remove it- dont miss the one or two screws on the bottom!
The power supply board is the one on the left (as looking at the back of the TV)
Look at the upper right hand corner.
There is an aluminum heat sink with capacitors to the right of it. Just to the right of the capacitors, there are two wiring connectors that jump over to the Main Board.
ITS THE CAPACITORS we want to locate-
They usually are about 1/2" tall about 1/4" around, wrapped in a brown or blue cover with silver tops.
Look at those tops, the silver part...they will be segmented into 3 or 4 parts..they should be flat.
LOOK FOR THE ONES WITH THE TOPS BULGING. These are your problem!
There are usually 2, sometimes 3 or 4 that are bad, but they are all right there in that little area by the heat sink.
The value of them is printed on the side of them.
usually they are 1000uf 10v or 2200uf 16-25v
you can get these at Radio Shack or online for less than $2 each.
here's the key-
replace them with the same value 1000uf or 2200uf whichever they are BUT
INCREASE THE VOLTAGE RATING.
Use 16v to replace the 10v
Use 25v to replace the 16v
Use 35v to replace the 25v
you will never have another problem with that TV.
grand total of your parts, under $20.
You just saved several hundered buck on that repair.
If you need more detail- contact me here.

Previous expert is right, I'm afraid, symptom indicates lcd panel (screen) is defective, vertical lines and light haze problem will increase day by day.
If tv is under warranty, call Samsung without delay for lcd panel replacement in warranty cover.
Below is an image of bad lcd panel of same model that got similar problem.
Hope these info will help you.
Thanks.
