Sony LCD TV Screen Goes Black When Watching a DVD Over HDMI

by Michael on March 14, 2010 · 37 comments

As I noted in an earlier post, we recently bought a new Sony Bravia LCD TV – the KDL-46W5100 to be exact. Unfortunately, in the time we’ve owned it, I’ve the screen has gone black a couple of times while watching a DVD. Worried that we might have a defective TV, I decided to investigate.


UPDATE – PROBLEM SOLVED: I replaced our cheap Philips HDMI cable with this 6′ Mediabridge HDMI cable, and everything works perfectly. Note that this cable is also available in 3 foot, 10 foot, and 15 foot lengths. Click through for more details on solving the black LCD TV screen problem.

The black screen problem

Just so we’re all on the same page, I’ll start by describing the “black screen” problem in a bit more detail…

For starters, we have our DVD player (Denon DVD-557) hooked up to the TV with an HDMI cable. The DVD player is also hooked to our home theater receiver (Denon AVR-687) for surround sound.

As for the black screen, every once in awhile when watching a DVD, the video completely drops out and the screen goes black for a few seconds. The audio seems to be okay, but I can’t really say for sure as we run that through the receiver instead of the TV.

A possible solution?

While I haven’t been able to solve this problem – yet – it seems to be a fairly common issue when the video signal is delivered to this particular TV via HDMI. Apparently the video signal is susceptible to power fluctuations (such as when major appliances turn on/off) and this TV is a bit finicky when it comes to signal quality.

One suggested solution has been to connect the DVD player using something other than an HDMI cable, but I’m not interested in doing that. Another possible solution would be to plug the DVD player and/or TV into an uninterruptible power supply (UPS) to “clean up” the power source.

We already have everything plugged into a surge protector, but I’ll probably try a low-end UPS (like this one or this one or this one) before trying anything else.

I guess a third possibility would be to try a different HDMI cable, though I’m not sure that would make a difference as the problem appears to be fairly widespread and not associated with a specific type/brand of cable.
