After updating to the new 10.5 OS my signal strength for over-the-air antenna is only showing one bar out of five. Before the update for most of my channels that I receive over-the-air broadcast was 5 bars out of five. This needs to be fixed.
Update: TV model TCL 55R617 Software 10.5 built 4198-30.
I will comment on this as I'm having the same problem since Dec 11th 2020 system update. This is a TCL issue but TCL does not have a community help site.
I have no signal strength bars as well, except for only one showing all the time - unless I click the "Home" button, then back to Channel button, then the signal bars show, but only for that channel. If I change channels I have to do the trick again for each channel.
I struggled with TCL on this issue for several days and told them it appears to be a software issue after the Dec 11 update. They ended up sending a tech who installed a new main board (for free) which did not fix the problem. Days later I got a phone call from a real TCL tech guy who said he was able to reproduce the issue on his personal TV. He could not give a time when the issue may be fixed.
Campagnolo4me, here is my latest response to another poster on this issue. Stay on top of TCL to fix this.
"I think the reason we're not seeing more complaints on this is most people use cable. I know Roku/TCL did not think I had a real problem in the beginning, even trying to say the TV was out of warranty. I had to fight to get further action.
TCL finally agreed to send a service person who installed a new main circuit board. But the problem persisted.
I finally got a call from a TCL engineer in California who said he duplicated the problem on his TV and that it would be fixed with the next software update. In April I got the update but it did not solve the problem.
I resurrected the original case # and got another call from a different engineer who said the replaced board was not synced with my model # (incompetent service guy) and that they would send another service guy to sync the board. They sent the SAME service guy who still had no clue about how to sync the board and said he was there to install yet another board. I refused and sent him on his way.
I then phoned the last engineer who had given me his phone number and he agreed to work with me to sync the board. We did this but it did not fix the problem. At this point I'm waiting for a call back from him as he is consulting with other engineers.
If it helps my case # is US04202109478 TCL should be aware that this is a widespread problem."
