Samsung flat screen TV’s

For the last 15 years I have only owned Samsung. YouTube and AVS forum is your friend. I have have been able to keep all three running by researching the problem and ordering the parts on line and replacing the defective part.. One needed a new power supply board or the other a mother board. Stick to the two top models 8 or 9 series. Total parts $144 plus my time. It takes longer to remove all the screws and extraneous stuff than it does the repair😤 I love what you can find on the Interwebs. My next set will be an OLED this summer before the Olympics start.

** P.S. Absolutely use a power conditioner,  power surge protector or Uninterruptable Pwer Supply with spike protection. Those parts run on very small voltages and can get fried very fast.

+1 oldhvymec, I totally agree that LOW voltage kills electronics. Probably the most important in my opinion. Think it's higher on the list than power surges. Just my 2 cents...

Ifyou want the best the LG OLED C ,or G seres best picture 
as well as super dependable I have owned 2 one newer the other 4 years old Fantastic , LG makes 85% of the screens out there in OLED screens ,and other companies design their own processors
or versions . The LG is the best OLED TVs and  better then any 8k , and if you want to see it at its best spend $350 to have it professionally calibrated which takes about 4 hours .there are many menus not available to homeowners as well as calibration equipment. The stores many times run special discs to Sony or others under contract I have compared them. All on a level playing field  and none are properly adjusted just average color temperature . 

You'll pay more for a Sony, but they are the only way to go for reliability and long life. Multiple Sony TVs owner for decades.

I have had the same results only one flat screen has had longevity and that was an early one with a subpar picture they are built as throw away items now sad to say.
