This model has had problems with electrolytic capacitors on the power supply which will cause your problem. I've fixed several of them by replacing these caps. The caps will most likely be bulged or mushroomed on top if they are bad. This is the most common problem that I have found on this model.

If it is in warranty, then I would just contact Samsung and they will send a tech out and he will fix it for you at no cost.

60 inch Samsung led smart tv model number un608h6203afxza,about 8 months ago it just pixeled out, today was watching a movie and picture just went blank? The first issue unplugged it ,and it worked


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

While watching it, picture and sound went out......


Hi am Vortash your set only being 7 months old is still under manufactures guarantee and it would be unwise to remove any panels or seals as this would invalidate the warranty .My advice is to contact a service engineer and have the set professionally looked at otherwise it could cost you an awful lot to put it right after wards .. .. The components in an LCD set are surface mounted and it takes special equipment to solder new components in or take them out .. Some of the component boards are multi layered and require anti static protection during service .. one wrong connection can damage multiple systems in the unit .. Regards Vortash

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J

Screen goes blank while watching


Couple of things:

1) When the picture "stops", does the standby light blink at all?
2) Can you post the model number please?

Some of these sets are known to have problems with the picture tube as it starts to age. There are some workarounds for this that can extend the life of the set for a short time. Without the model number though, I can't confirm that this set is in that catagory. Please supply responses to the issues above and we'll continue from there.

Thanks,
Dan

Samsung 40 no picture


If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.

Blank Screen Problem


Does the menu come up? If it does, then, the source could be the problem, such as the cable or DVD player. If the source is not the issue, then, the problem would be in the Digital or Analog PCBs. If the menu does not come on, then, the problem is more than likely the DMD. If it is not the source then call a local authorized Samsung servicer in your area. Contact 1-800-Samsung. Hope this helps.
