Many versions of Sony LCD televisions are having issues with their HDMI connections. HDMI or (High-Definition Multimedia Interface) is a digital connection between two devices. Unlike their analog cousins, HDMI requires both devices to be able to “talk” to one another. Failure to do so brings a variety of unwanted symptoms. Think of it like a PC and printer hook-up. If you don’t have the right drivers installed or there is no “hand shake” the printer doesn’t work.
Now HDMI problems are nothing new and probably every brand of LCD television has experienced one, but it is a common ailment for many Sony LCD televisions. Most notable among them is the HDMI 1 port flat out doesn’t work at all. It can affect other HDMI ports, but this one seems to get hit the most. Essentially the HDMI port cannot “sense” that there is something hooked-up to it, so no signal gets processed.
So, if this happens to you what can you do? Well before you panic there are a few things you can try first. Just like the above mentioned example of the PC and printer, what do you do when they lock up? Reboot, of course! Try unplugging the power to the TV and whatever device (DVD, Converter, etc…) it’s hooked-up to. If that doesn’t fix it, it’s time to dig deeper. You can try plugging your video source into one of the other HDMI ports on the TV. If it works there but not on port one, most likely it’s bad. If you have another HDMI cable you can try that too just to eliminate it as a possibility, but bad HDMI cables are usually the least likely culprits I’m afraid.
If plugging into a different port doesn’t work try a different video source. If it works with a different device either the original device is bad or there may be a compatibility issue between devices. When this happens it’s usually a glitch that a software update will be required to correct. You can contact Sony on their website to see if a new software update exists for your LCD television.
Now if all signs point to the HMDI port being bad and software doesn’t fix it, only replacing the main (or mother) board in the set will fix it. This can be outrageously expensive as the prices can range from about $150 to over $700 for this board depending on which model you have. And that’s not including the labor charge that a repair company will hit you with. In many cases this would not be cost effective to have repaired.
What are your options? Well you can still get High Definition using the component cable connections on your TV. I would use it on the cable or satellite box since most of them still only put out 1080i or 720p resolution. Save the other working HDMI ports (if you have them) for devices such as a Blu-ray DVD player which needs HDMI to deliver 1080p resolution.
