Question about RCA F32649 32" TV

1 Answer

TV will not come on and if it does it just cycles through the channels...

The TV will not come on. With the remote control I can hear it click on but immediately it clicks off. The buttons on the front panel don't work at all. I took out the circuit board that has the micro switches on it and checked them out with an ohmmeter and all of them work. Sometimes I can get the TV to turn on but then the channels just keep cycling through one after the other. It will not stay on any one channel.

I put the TV in my garage (unplugged) for about a week then tried it again and it worked perfectly for about two weeks then the same problem again. I don't know what to do to fix this thing and I can not find any repair places in my metro area.

    how can I bypass the tuner? It won't allow me to change to the other inputs. If I try to switch to the other inputs it immediately switches back to channels and cycles. That also does not solve the problem of it not staying on. It does not appear to be a tuner issue but rather a programming problem.

If tuner channels keep cycling,why not by-pass the problem?
Use audio / video inputs as source from box or VCR tuner....

    Sorry my suggestion did not help .....I agree that you

    do not primarily have a tuner issue. Possibly a power supply

    problem affecting common circuits.....leaky regulator or diode or

    bad electrolytic capacitor........Using schematic, check all power

    supply source voltages = if all are good, suspect bad solder

    connect since set works sometimes.................Last suspect is

    bad microprocessor IC or a part in it's circuit..................T.

My RCA tv won't work without a remote, and I can't seem to reset since I don't have a menu button


Hello
If your TV has no menu button on its front panel, there is no other way than buying a universal or original remote control to this set.

Press the POWER button on the front of the TV. If the TV turns on, check the remote control solutions on page 26.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).Buttons don't work
• If you're using the remote control, press the TV button first to make sure the remote is in TV mode.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).• Unplug the TV for two minutes and then plug it back in. Turn the TV on and try again.TV turns off unexpectedly • Sleep timer might have been activated. Go to page 24 for instructions.• KidPass might have been activated. Go to page 21 for instructions.• Wake-Up timer turned on the TV and no remote or front panel buttons were pressed for two hours.• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then
turn on again. If this happens frequently, the voltage in your house may be abnormally high or low.
• Unplug TV. Wait five minutes. Plug it in again.

Volume control does not work using the TV's remote, the cable remote or the actual volume control button on the front of the set - the volume that comes out of the TV's speakers is constant - about 33% of...


SO YOU JUST GOT A NEW TV ...BUT...THE VOLUME CONTROL IS NOT WORKING FROM YOUR CABLE BOX.

EASY! BRING UP THE IMAGE OF YOUR REMOTE FOR
YOUR CABLE (MORE THAN LIKELY, IT'S A UNIVERSAL).

CLICK ON THE REMOTE FOR INSTRUCTIONS FOR VOLUME LOCK.

IF IT'S A UNIVERSAL REMOTE, CLICK SETUP (TWO BLINKING LIGHTS) TYPE 993, AND HIT CABLE BUTTON.

VOILA! YOU CAN NOW CONTROL VOLUME FROM YOUR CABLE REMOTE!
