Sometime around the early-middle of June, many of my previously working QAM HD channels stopped showing a signal.  The channels lost include WISN, MPTV (all 36.x), CBS 58.1 and WMLW 58.2.  I've tried adjusting the co-ax cable, changing co-ax cables, re-tuning, and nothing works.  I can still get these channels on the normal TWC settings in SD, but no longer in HD.

Has anyone else had this issue?  The TV in issue is an LG 32LD350.  Thanks for any help!

It was working last night at my house.

I'd try a different outlet in my house and another set with a QAM tuner if possible.

TWC shuffles these around (changes actual RF channel) now and then.  Do a full rescan.

Have you verified that you are scanning everything?  Is it possible you toggled from CATV to OTA?  

I no longer have TW, but it seems to me that my LG has two or four different scans, covering OTA NTSC and ATSC, and CATV NTSC and QAM.

I have done a full rescan several times, which on that TV, usually takes around 30 minutes.  And that is my only TV w/ a QAM tuner on it.  My primary TV is an older-model Samsung plasma w/o a QAM, so I can't check whether it works on another TV.

There was a notification earlier this summer, I think, about the Clear QAM shift.  Is it possible they shifted the channels to a frequency that is above the threshold on your distribution "plant"?  For example if you have 300 or 600 MHz splitters, or RG-59, that could cause a problem.  

Are you able to receive OTA ATSC signals with this set?

I am having the same issue with channel 58.1 on my Samsung LN-T1953H. When I rescan should I select STD, HRC, or IRC digital scan? THANKS!
