I have an HR-20 that has been acting up for about 3-4 months with 1 OTA tuner on 1 channel. Problem happens with my local NBC antenna channels 11.1 & 11.2 on 1 tuner cannot be watched (major pixelization). This is what I have done to trouble shoot the issue. Plugged antenna direct to TV – no issues with cannel Restarted dvr numerous times. Left DVR unplugged for about 24 hours. Reset antenna setup – problem still exists. Reset DVR to factory – problems still exists. Reset antenna setup – problem still exists. Checked other receivers with AM21 OTA – no problem with channel Again this is only a problem with 1 tuner and the only way I can duplicate is to start double play and go to 11.1. Yesterday I finally put a call in to support after 30 minutes of support trying to resolve, nothing. I was then transferred to the protection plan and they told me the only thing I can do is to have a tech come out. I asked for them to send me a replacement and not waste the time of a tech. The answer was still no, I then asked for a supervisor………..the answer was still we need to send out a tech to check cabling, multi switch and dish alignment. I told her this has nothing to do with mulitswitch as it is the antenna and the antenna works on the other 2 dvr’s I have. I just can’t believe that they would send a tech out to look at this for 1 second and say yep we need to replace your receiver. I was just trying to save them money and even asked if I could pay for shipping, answer was still no. I then asked if I can go buy a receiver and get a credit and she said I doubt it. Anyone else have another way around having a tech come out? I know the tech coming out is free but it just seems that it would be easier to send me a DVR.
