Hi there,

I just bought a 40 inches Samsung LN40A550 and the Samsung upscaling DVD (DVD 1080P8). There connected with an HDMI cable but when i'm reading a DVD, every 5 minutes, my TV is losing the signal for about a second or so. I've checked my DVD manuel and it seem like when the DVD is upscaling the images, the TV as some problem getting the infos. I hope you understand what my problem is, and if so, what's the solution? In the meantime, i've connected them with component cable. The problem is solve but the resolution went down a notch.

Have you tried a different HDMI cable?

Could be some buffer problem in the DVD Player.

What do you mean by '' a different HDMI cable'' Another brand? Presently, i was using a Rocketfish RF-G1138. About the buffering problem in the DVD, is there a way to fix that?

As in a different one. It could be that that cable is defective, although it sounds more like a handshake problem to me. Try a different input as well on the TV if it has multiples. Do you have any other HDMI devices you can test it with?

This may not be the same problem but it sounds like it could be related.

I purchased the Samsung LN40A550 40" 1080p LCD HDTV on July 14, 2008. It's my 4th big screen HDTV purchase but my first 1080p box. Agree with other reviews in that it has an absolute beautiful picture at a very good price. There are many features I love about this TV, but here's the problem....

I purchased a Samsung 1080P8 upconverting DVD player with an HDMI (version 1.3) cable. When i watch a DVD, i get a 'searching for signal' message that appears on the screen for about 5 seconds. This happens once every minute or two! I went into full troubleshooting mode by replacing the cable, the DVD player, and everything else i could think of. I tried the DVD player and HDMI cable with my other HDTV sets and it worked great. After calling Samsung technical support and getting to their level 2 support in New Jersey, they acknowledged there is a problem with the HDMI connection with the TV but they do not have a firmware fix for it yet. They suggested i wait for the firmware fix (release date unknown), or return the TV and try another one. I opted to exchange the TV for the same model. I received it today and (unfortunately) it has the same problem. I will now return the TV to Amazon, get a refund, and purchase a different model.

Bottom line, if you don't use or need the HDMI connection, you should be fine with this set. However, if you plan to use HDMI I'd look to a different model until this is fixed.

Update on July 28 - After further troubleshooting, the HDMI problem is with the combination of using a Samsung LN40A550 40" 1080p LCD HDTV with the Samsung 1080P8 upconverting DVD player. Together, they do not work. Separately, the upconverting DVD player works perfectly with other TVs, and the Samsung LN40A550 works fine with another upconverting DVD. I purchased the same brand so i would eliminate this exact problem! Who would think that Samsung has not tested their own product compatibility before they go out the door? Exremely poor quality control - my guess is they have a problem with their 'anynet' software feature, but it still blanks-out with 'anynet' turned off. Purchase the Sony upconverting DVD player with this TV and you'll be OK. However, now I personally don't trust Samsung.


The comments for this review also talk about this being a known problem with some but not all of this model. And one even seems to describe the exact problem you are having. I suggest you call Samsung and see if they have a firmware update yet or any other suggestions that might help.

Dean - looks like you earn many good karma points for identifying the problem before Ghis goes crazy replacing one piece at a time of his system and still ending up with the same problem.

If the above is true, someone in Samsung's Quality Control team group needs to be shown the door... Unbelievable.

On a general note - why is HDMI so hard to get right? It's been around for quite some time now and still plagues many manufacturers and devices. Buying any newly-released HDMI device that hasn't been tested by the masses seems to still be very risky business. It seems to me like we should be past that point given the age of the technology.

HDMI is a really crappy standard, basically. Poorly designed connectors, mandated copy protection (this causes most of the problems) with ever changing specifications, and poorly chosen cable design. Here's an Audioholics article about it, but not the rant one I was looking for.

I hope it’s a simple fix for him whatever it is.

Hmm.. nope, that's not it! It was something about how the cable was just poorly designed--should have been coax.
This one! which was linked in the article you posted.

All I know is that HDMI (well, most are probably as a result of HDCP) sucks big rocks. I hate it. I put my extended family's setup with component only if at all possible.
