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 would suspect your control buttons on your front panel on the set have become shorted. specifically the volume buttom down. This is freezing you control functions. like someone is holding the volume down button all the time. or intermitantly. this cuircit board is on front of the set. I have seen this problem a few times at the shop. The common repair is to replace that button assembly cuircit board. I believe the last time it cost the customer around 85 dollars, but like all things depends on the part and the technician that puts it in.
While TV is on, simultaneously press and hold both the TV's Volume Down button and the remote's PP/Play button for 7 seconds.
This is the procedure for resetting the lamp timer. Have you ever replaced the lamp before? The lamps usually never last 5yrs.
Hit the set up button on the TV. You'll see options to change the language. The last option is to put the TV in "Demo Mode." Put the TV in Demo mode, when the first screen appears, "Welcome to...." the PIP will disappear. Hit exit before the screen moves to the "Menu." If you miss it, watch the demo once--it will restart--and hit the exit button the next time you see the "Welcome to" message.
I just did this and it worked for me - i hope it works for you.
i would say that its time to put that tv to rest is it a projection tv? if it is then it may be the bulb but i would recomend just getting a new set because repairing your current one will cost alot and wont last long so a new one is a better option
21 error code means the set is shutting down due to xray protection. Try removing each one of the CRT PWBs one at a time and try powering up the set. replace previous removed CRT PWB before trying the remaining CRT PWbs. let me know the outcome. Please respond to this same post when replying
Okay try to distinguish if the three blinks is 1 pause then 2 blinks or 2blinks pause 1 blink. As the set will only blink a two digit code 12 meaning no error detected and 21 meaning the set is hutdown due to xray protection.
if the remote eye on the tv it will do all kinds of strange stuff once the eye on tv gets dirty the the tv will shut off after 2 seconds try cleaning it and see what happens the eye on tv is hard toget to so get a can of air to blow it out i took my pocket knife to clean mine i know that was ruff on eye but thats all i had if this dont work try unpluging your control board on front of set board may be bad or buttons are stuck email me at firstname.lastname@example.org if this helps
