My Samsung LED TV has gone dark. I did a chat with Samsung and a remote service. No help. I've only had this SMART TV for 1 year and 6 months. wow.

Hi and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, even if the TV "...has gone dark...", is there still sound?
Customer: replied 2 years ago.
Yes. I can see the picture, but it is very dark. This has just been in the last few hours. Initially I could turn it off and when I turned it back on the picture was fine for about 30 seconds and then back dark.
Customer: replied 2 years ago.
Sound is fine.
Expert:  Louie replied 2 years ago.
Appreciate the additional information.
The described symptom then almost always point to an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multimeter?
Customer: replied 2 years ago.
I do not have access and am not familiar.
Customer: replied 2 years ago.
I'm all about DIY if this is fixable.
Expert:  Louie replied 2 years ago.
The above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs.
If no meter, what can be done then is straight replacement of the suspect board. This would then serve as both an attempt of a fix and as a test by process of elimination.
Would this approach serve your need please?
Customer: replied 2 years ago.
I'm really not sure what you mean.
Expert:  Louie replied 2 years ago.
Since no meter available, what can be done is just to replace the suspect board even with no voltage measurements done.
Would this be an acceptable method?
Customer: replied 2 years ago.
How do I do that?
Expert:  Louie replied 2 years ago.
What I can do is point you to the suspect board; i.e. give you the part number and even where it can be bought.
Upon purchase/receipt of this replacement board, open the back of the unplugged TV and carefully perform remove-and-replace.
Would this be something you would be comfortable in doing?
Customer: replied 2 years ago.
Not sure. How hard is this?
Customer: replied 2 years ago.
And how much will this cost me?
Expert:  Louie replied 2 years ago.
Sorry, but my participation is strictly limited to repair & technical matters.
For payments & billing concerns, please contact Customer Support.
Customer: replied 2 years ago.
You have no idea around how much the "board" will cost. Wow. I don't think Just Answer Customer Support will know either.
Expert:  Louie replied 2 years ago.
I misunderstood the "...And how much will this cost me?..." as the board cost was not specified.
The online seller is offering the board for less than US$30.00
Would you then consider the DIY?
Customer: replied 2 years ago.
How hard is it to replace this board?
Expert:  Louie replied 2 years ago.
No soldering; unplug 3 or so connectors, remove ~4 screws, lift suspect board. Place in new and do the reverse.
DIY?
Customer: replied 2 years ago.
Can I get with my husband and respond later today?
Expert:  Louie replied 2 years ago.
Yes of course.
Post back with an update when able.
Cheers.
