Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
What's the model number off of the back of the Samsung and how old is it please?
Thank you for the reply. This wouldn't be a pushbutton fix, but rather the start of a fault in the Mainboard of the set (loud static, horizontal lines and then it power cycles itself). Ultimately the only thing on a user level you can try is to unplug the TV for a length of time to reset the processor. If it goes beyond that the mainboard needs to be replaced. I can search and see if that board is available and for how much if you'd like .
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 $85 (but is currently showing out of stock):
Alternatively, if you're not comfortable with this type of work, then at a shop this is $250-$275 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:
