My H23 got fried yesterday. All I get is searching for signal. I have tried different outlets in my home with the same searching for signal. All other receivers are fine. PP is insisting on sending a tech instead of just shipping me a box. I mentioned that I have an offer on DirecTv.com for a free HD Dvr upgrade. PP wanted $50 to replace H23 with an HD DVR. If I go thru the process ob DirecTv.con I only get charged $20. When the Tech comes tomorrow will he be able to replace H23 with HD Dvr since I am eligible, or do I have to go thru DirecTv to upgrade?
