Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

    Thank you, Don't think its the back light. I can see it through the back of the TV and the front glows, but no picture. There is a small white square on the bottom right on the screen though.

You might want to try reseating all of the ribbon connectors that connect to the tcon first, but it sounds like you may have a bad panel(screen) which is probably what made the original tcon die. The only other possibilty would be the backlight inverter board(either the master or slave depending on which side the dark area is on).

Why won't the Samsung Authorised Dealer repair the board? It's not that difficult!
There will be a power fault and the picture is not "building" properly. At worst it will be one of the memory chips.
With a reflo soldering machine, no problem.

I've watch your problem on youtube , that problem can be from main board. But to make sure main board problem, you should check without inputs first. Unplug all input (HDMI, Component, AV in, PC).
Than turn on your tv again. If that conditions still appear, i suggest you to call samsung technician to repair it.
Good luck.

My Vizio Smart TV has no sound

Sounds like you may need to replace the audio circuit board. If you are comfortable with taking apart your tv, you can find a dealer on this site who provides new and refurbished circuit boards for televisions. It is a shame that your tv is so new and causing you issues. Good luck and have a great day!

Samsung cs21m40mj no picture

I don't know if this helps, but I had the same problem in reverse. Great picture - no audio. I finally unplugged the TV and all devices connected to it (DVD player, cable box, etc.) waited 3 minutes and plug everything in. The audio was restored.

My 3 year old Proscan 42" LCD TV picture suddenly

On the far left and right inside the back on panel are inverter boards. Replace or look for capacitors buldged, swollen, or cracked on their tops. Replace defective caps with original value and make sure replacements are 105 degree for longevity. Common problem, let me know if this helped.

No picture anymore

I found one of these at the dump with the same issue. Bought a Z sustain board for $75 , replaced it and it works great. I plan on installing some PC style cooling fans in the cabinet as heat is what destroys these sets
