Sony Grand Wega KDF-55XS955. I have been using an HDMI port to connect back and forth from my PS3 and computer and it worked for quite some time. Then one time I was switching between them and the tv stopped acknowledging that there was anything connected. I've tried multiple other devices and switched the cable but the result has been the same. I have used the same devices and cable with the 2nd HDMI port and the TV acknowledges them fine. Anyway, I'm not sure how to fix this problem. PLEASE HELP!!
This sometimes happens on my Samsung tv. With the tv switched on try unplugging the tv from the mains supply and leave for 3 minutes then plug back in and try. I hope this helps.
Testimonial: "Wow. It seems to have worked with one additional note. After plugging back in I had to rotate inputs until I came back to that one and then it showed up. Thanks VERY MUCH for the no cost solution."

Authorized sony repair center told me the problem was the Q Box. Ever
heard of this? Part runs about 300 bucks. TV is out of warrenty as it
is 2 years old. Do you think it is worth it to fight sony and get them
to replace the part or just fix the TV?
Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.
read this if you think it's the same problem

I would have to say you have a bad projection lamp!! They do NOT last forever!!! About 3000 hours is normal. If this is out of warranty--about $300 in--house repair or so.
