When trying to turn TV on for last week or so, had to push button (remote or on the set itself) at least 7-8 times. It would finally come on. Then yesterday while watching it, it just made a loud noise, and went off. When I tried to turn it back on, it came on for a few seconds, made the loud noise, and went back off. Now it will not come on at all. It is an RCA Home Theater. Made in 1992. Model #P46130W1C. Any ideas?

I had come home about a week ago and pushed the power button from my
remote but my tv did not respond. So I just went to the front panel and
pushed power but once the tv turned on, the volume was on full blast! I
used the front panel volume decrease to get the volume down, but when I
stopped pushing the button, the tv increased its volume to full blast
again by itself! Naturally I just turned the tv off for a few moments. I
tried the remote again, no response again, so I used the panel power
button. The tv volume was still full blast when it turned on but after I
decreased the volume it stayed this time. The picture is and has been
perfectly fine and the tv was working fine. The next day the problem
started all over and now once we turned it off from frustration of
having to manually use the panel to change channels, it now will not
turn on at all. I have changed batteries from my remote, reprogrammed my
remote, pushed system reset several times, unplugged it for a while,
bought a new surge charge, and even held the menu and device panel
buttons for 10 sec and tried to turn the t.v. on again! What other
options do I have or what may be the issue at hand and possible parts
that may need to be replaced?? Thanks!!
I assume model number here is correct--if set is scanning either just up or just down in channels that is an issue with the related button on the set itself.
I am going to take the time to explain here as I want to help you.
Let us say for example when turned on set scans UP constantly thru the channels and will not stop. Remote seems not to work and has no effect on this.
What you have in this case (if scanning down different button) is the up channel button on the set is BAD. It may look perfect but it is the cause of this (trust 30 years of TV repair here).
Each button on the set itself has a tiny micro switch than when the button is pressed acts to perform that feature and when released stops.
Keyboard (the button array) has priority over the remote--hence the remote cannot stop this action.
The tiny switches fail in exactly this way--instead of when released stopping they still try to function.
This is rare but I have seen in a few hundred sets this kind of problem--be grateful it is not the vol up doing it.
How to prove and or solve this issue?
Someone needs to gain access to the pc board with the buttons/switches and disable the (channel up or down) switch causing this problem--most switches will have just two pins to unsolder to do that---may be a few more pins for mounting but only two for the switch.
Many sets if the keyboard is up front also have the remote receiver there so you if that is the case cannot just disconnect the board.
With the correct switch (push button) eliminated out of circuit the set will work normally with the remote.
Repair: either locate and replace the entire tiny board or just leave the offensive button disconnected and use just the remote for that function.

Noway to turn off captioning right away without the original remote.But U can unplug the tv for an hour,tv well reset itself back to original setting.The Captioning will shut off buy itself.Because captioning reqiure CC buttion on orignal remote and must manually turn on and off.
I suspect the unit might need service. If it were only the remote, new batteries would, of course, be in order. But that part about the manual power button being ineffective suggests something else is affecting the set. Sorry.
