Purchased a 2018 75 inch Q9F last Wednesday from Best Buy. Same problem with the tv turning off and on by itself and the remote locking up with the flashing red light AFTER ONLY 2 DAYS!!! Already downloaded the latest update and turned off the HDR and power off, etc. etc. Seems I need a new connect one box and cable sent to me, BUT how long before this fails again since Samsung has obviously ignored this issue for the last 2+ years with so many complaints. Very angry and disappointed with Samsung and the thousands of dollars and time wasted on this known defective product!
A bit of update on my case.
After one week of not having TV the repair guys called me to say that SAMSUNG is OUT of stock of the spare parts and they don’t know what to do?????????????????????
SAMSUNG ???? REALLY???
What is going on here had the television less than a week (Samsung Q9FN 55) and all I get is off, on, off on I tried everything. I feel like I have flushed money down the toilet buying this tv now.
I’m about to try my 3rd Q875 in 82 days. Both lasted exactly 40 days and became useless power cyclers. Fortunately Best Buy has a 45 day return, so the 3rd is coming Tuesday. Seems all the lower level support people are very familiar with the problem. One told me my model number of the last one was from a “bad batch”. Of course the supervisions do not acknowledge any issue. I just got off the phone with a supervisor an I will know tomorrow if they will do what she suggested. If they do I will pride them all over the internet , we will see.
