We were flipping breakers to find the one our stove was connected on, and our TV was turned off at the time. It has never given us a moment of trouble before, however, now it will not turn on at all. The front buttons won't work; the remote won't turn it on. We've put new batteries in the remote; unplugged the TV for several days even before plugging it back in. We tried every trick in the RCA User's Guide under "TV Won't Turn On." Nothing. It's a P32649.

Re: TV will not turn on
Assuming you are absolutely sure the TV is getting power,
If you have an ohmmeter, measure the resistance between the two prongs
on its plug. If no conductivity (over 1 meg Ohm) the fuse inside
is popped. Take the cover off, look in the area near the
power cord, it is the usual 5AG type (glass cylinder) fuse.
If you replace it and it pops again then measure all the diodes in the
rectifier circuit (near the fuse).
Many times power transients will just blow these input power
devices. However, many times it will go much deeper and get
the TV's processor brain. If the TV is anywhere near 10 years
old, I wouldn't go any deeper than the input power circuit.

Just press the buttons on the TV randomly, sometimes this combination works in starting the TV w/o a remote. After that use the remote for the dish to flip channels, but you will have to set the sound manually from time to time.......sodeep
7 Blinks is the code for high voltage shut down and can be due to a failure in the horizontal deflection circuit. Since it worked before it was moved, i would guess that you may have disturbed a bad solder connection or possibly cracked a PC board. IF you feel comfortable doing so you can give a visual inspection of the board With the power off and TV unplugged remove the back cabinet. Slide out the board and flip it over to check for poor solder connections/cracks in the traces.
The only possible check that could be done without removing/opening the Audiovox TV would be to check for the presence/absence of supply power/voltage depending on how the TV is powered (12VDC or 120 VAC). Normally, there would be an fuse and/or circuit breakers.for the RV's entertainment system including the TV.
The 120-volt circuit breakers and 12-volt
fuses are located in the same compartment. These devices interrupt the power if
the circuit is overloaded.The 120-volt circuit breakers include a 30
amp main breaker and several smaller breakers for individual circuits. If a
circuit breaker is tripped, look for an overload on the circuit, then reset it
by turning the breaker OFF and then turning it ON. Do not try to reset a breaker
the second time without locating the overload problem. The 12-volt fuses protect
individual circuits. If the circuit is overloaded, it will blow the fuse and the
fuse must be replaced. Check the circuit for an overload and replace the fuse
with the same type or amperage rating.
If the above checks out, then problem is internal to the unit and would require removal from its current position.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Sounds like it is probably just a fuse inside the t.v. May also have a bad diode. I would take it in for an est. if you don't feel good about replacing the fuse. Always have your t.v. unplugged when working on it.
You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
