I have a 37'' Sony Bravia KDL-37XBR6 that I purchased in July 2008. I also have a Time Warner HD cable box that also has a built in DVR.
The HD cable has been connected to the HDMI 1 port. It worked just fine for awhile but then I began losing the cable signal. The TV displayed a warning that the HDMI port I was using had lost its signal and that i should change to a different HDMI port. I switched the cable to the HDMI 4 port and it worked fine for a couple of days and then I lost the connection again.
I have now connected the HD cable to the HDMI 3 port and it's working. Any idea what's wrong?

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!

You did okay but the phono sockets are not for Computer/TV use. Phono sockets should be checked int the manual on why they're there. If you have connected the Bravia to your computer, using the appropriate cable, then you should also purchase or request from the retailer where you purchased the TV a cable that has stereo phono plugs and, you didn't say what size phono sockets they are but I presume they are 3.5 mm. So, if the TV has 3.5 mm sockets, you purchase a cable with stereo 3.5 mm plugs. This is adequate for the stereo wav sound coming from the computer and going into the TV. Remember, having 2 Phono inputs on the TV doesn't mean anything. The TV could have a number of video inputs too, ATD AVT, AV, COMPONENT1, COMPONENT2, HDMI1, HDMI2, HDMI3, etc. each have it's respective sound inputs for AV, S-VIDEO, DVD, Blue-Ray, etc. But for the computer there may be a different type of socket for it's sound inputs, normally it is the old phono sockets. Seek help from the retailer or else you could cook the circuitry of the TV's sound system.

I also have the same problem and was wondering if you ever found out the answer to this problem Peter?

I have a Sony Bravia model KDL-46s5100 that had the same problem. All HDMI ports stopped working. I don't know why this works but unplug the TV for about 30 sec, then plug it back in and hold down the power button on the tv for 10 seconds. Like I said I don't know why this works but it worked for me. Good luck.
