Samsung ln52a550 hdmi doesn't work - "no signal"
by carepub2008 - 11/19/11 10:18 PM
I purchased a Samsung TV Model No LN52A550 in 2009. We have been having issues with this TV from the start but unfortunately didn't return it in time.
The HDMI has worked on and off. Resetting the input, turning the TZ on and off would work for a while, but now, there is nothing we can do to get the input to recognize HD input. When a working, tested HDMI cable is plugged in, we get a "no signal" message.
I've tried updating the Firmware to no avail. Tried connecting directly from cable box, through DVR, PS3, DVD, etc and every combination in between. I'm resolved to fix this once and for all. Despite all the posts on this issue since 2008-2009, there is no definitive answer.
Can anyone help me solve this or let me know if it can be fixed by a tech?
