Question

Sony Bravia screen going blank for a few seconds

Aug 19, 2013 4:25PM PDT

We have a Sony Bravia KDL-60NX801. Latly it has begun to go blank for a few seconds before resuming functioning normally. It typically does this 3-4 times for periods that last 2-5 seconds, then works fine for a while (maybe 30 minutes), before beginning the cycle again. Any ideas?

Best,
Rob.

Is the video source over HDMI?

If so, try a new cable and another HDMI port. This issue is well discussed so I'll shortchange you about HDCP handshake discussions.

Unfortunately, not so simple

Unfortunately we have the same problem with video coming from multiple ports, cables, and devices--cable box, Blu-Ray player, and X-box. Cable box and Blu-Ray each have their own direct link to the TV over two separate cables. The XBox goes through the Blu-Ray player first and then shares the HTML cable and TV input. We even get this problem with Netflix, which is built in to the TV, so no video cable involved.

Sad to read.

Call it in and ask for service. They should have you check the firmware version but as presented it sounds like a hard fault.

We've been known to replace boards ourselves
Aug 21, 2013 6:50AM PDT

My wife and I are quite handy, and we've been known to replace boards ourselves, if we can figure out which ones are the problem. We haven't repaired this TV ourselves (yet), but we did replace two boards on our previous Samsung, and extended its life a good few years. Any idea which board(s) may be the problem here?

The one with the HDMI chips.

Ask shopjimmy which board has those. Right or wrong I don't go any further without a proper service manual. I'm pretty old school about such repairs.

I had a Sony 70 that had the optical block problem then was replaced with a Sony 60 that has a bright blue line going right down the middle of the TV. Sony will only give me a 20 percent discount which is what it costs at best buy. They replaced a defective with a defective and only give 1 year warranty on both. I realize that there are lots of scammers out there, but this is not the case. I spent lots of hours trying to get the defective TVs replaced because both cost more to fix than what a new one does, and all that is done is ''go buy a new one''. Sarah Kepler helped me the first time and she cares. But that is the old Sony. Sarah is now with a different department and they won't let me talk to her. They won't download a picture or take an TV repair shop invoice saying its beyond repair. I bought Sony TV's all my life but will NOT continue because of the new so called Sony listens department. They will not stand behind their quality any more. Would you go buy a TV after the last 2 have been defective? And no one cares......I spent 4500 on the first 70 inch defective TV .And settled for 60 inch that was defective. Sony used to CARE.......Sure miss good people like Sarah Kepler...
