Re: Black screen periodically

JUMP TO SOLUTION

Update:

 

my 55" Samsung has had this issue since purchase. 

See my earlier posts. 

Here is a better description:

regardless of input source the tv would go black and lose picture and sound for 2-10 seconds at a time. It would return to "normal" on its own. This got progressively worse to the point it would happen at least once every 5 minutes. 

Something else worth noting. If you were quick enough and had the smart remote in hand you could still pull up the Samsung "hub" menu from he black screen. 

This told me that it was most certainly signal or input related. 

Swapped power outlets 

swapped cable boxes

swapped hdmi cables 

swapped inputs

tried to reset to factory specs

tried to search for updated software 

basically narrowed it to the tv 

 

called samsung 

they set up to have a repair facility come out. 

 

The repair guy called me and basically said he is very familiar with the issue and would order a mainboard and power supply for the tv as this is the problem. 

 

Well fast forward to two weeks and the repair man comes out and fixes the tv. No further issues to report after a week. 

 

So, if you have the issue. Its most definitely the tv. Call and get it repaired or return it. 

 

My my issue is now solved. 

Hope this helps someone else.

Factory reset solved the problem for 2 weeks.  I have the latest firmware.

 

Now the black screens have returned, and now the screen also slowly darkens after being on for a few minutes.  What a piece of junk.

 

Despite having a "satisfaction guarantee", Best Buy has been no help at all.  That's the last time I buy from them.

Just to clarify, dose your screen go completely dark? It sounds like you may be having a different issue. Thank you.

Drew - it goes completely dark for a second or two and then comes back on. This happens intermittently. Some days frequently and other days not at all.

Does the screen only darken on one source or all? Smart Hub?

Yes, two issues.  The screen periodically goes completely black on all inputs.  Recently, the screen also started dimming itself on at least 2 inputs (cablebox and smarthub).

BJwright- Can you confirm if you have the most update to date software? The version can be found under the menu in Support > Contact Samsung. Also, have you attempted a full factory reset since this began?

 

DaveB2- It seems your television will require service, I've gone ahead and sent you a private message concerning this. I look forward to hearing from you!

Service came out last week and replaced the main board.  It didn't fix the problem.  The TV went black again last night and again this morning.  I asked the tech why he didn't replace the power supply too.  He claimed the power supply wouldn't have these symptoms.

 

Samsung, how about actually diagnosing and fixing this problem???

I think this has to do with the little black switch box for the hdmi ports etc

Are you using HDMI 2.0 cables?
