Are you saying the screen flickers without you actually pressing the power button to turn it on? Also does the Samsung welcome logo display normally?

when i plug it in, there is a dim flicker. that's it

Once more- so you're NOT pressing power to turn it on- it just starts flickering on it's own?

Please reply back to exactly what is asked so I can help you.

correct

How about the power light- what's that doing when you plug it in?

Ask Your Own TV Question
Customer reply replied 4 months ago
no lights on the front. I can see a few white lights blinking through the slots in the back

Are you looking to repair this yourself?

Customer reply replied 4 months ago
if its as easy as pressing a few buttons, sure... otherwise, no way

No, it's not a button thing. Please standby.

Unfortunately this indicates the set's Mainboard has failed and needs to be replaced. This is a "plug and play" part- meaning no soldering or special tools are needed to replace it. Only a screwdriver and about a half hour of your time. That part can be purchased for your set at the link below for $70:

https://www.bonanza.com/listings/Samsung-UN50EH5300F-Main-Board-BN94-06882C-BN97-06298N-BN41-01812A-/555582162?goog_pla=1&gpid=177431040781&keyword=&goog_pla=1&pos=1o2&ad_type=pla&gclid=Cj0KCQjwkd3VBRDzARIsAAdGzMD0PvbK270D7J_UYY2CO0QhAcI_bYVRgqHiM8kSkgs3hXKYKUd5OsMaAiCJEALw_wcB

Alternatively, if you're not comfortable with this type of work, then at a shop this is $200-$250 parts and labor, which is typically not cost effective as a brand new 42" LED Smart TV starts at around the same cost. However if you'd like to inquire on repairs, or seek a 2nd opinion, you can use the link below to locate a shop in your area if you'd like:

Other than that, I'm sorry for the bad news and wish there were a quick fix.
