Hi folks, I have a HR24/100 receiver. Last night the screen went white, when I tried to rest, I gat a message that the receiver was over heated (above 60 C). After about 20 minutes, the message said the temp was down to 59 C. No other functions would work. I finally turned it off, but the “record” button continued to flash. This morning same overheating message, still reports 59C. Any ideas?
