I have a RCA P52755ST that won't turn on. When I plug it in it makes a whining noise then stops. None of the buttons in front work or the remote. Can anyone help? Thanks

Re: RCA P52755ST won't turn on.

Thanks! I will have to call a pro for that unless you think an amatur can do it. I am very mechanically inclined. I'm not afraid to jump in. Could you tell me what fuse is used for the power supply? I went to pop it out to check it and it flew to the front of the cabinet and I can't find it. Thanks again.

My RCA Truflat T.V won't turn on and the FPA lock is turned on, I have the original remote. what should i do?

TV won't turn on • Press the TV button. Make sure the TV is plugged in.• Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else.• Something might be wrong with your remote control. 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.

RCA F32650 production May 2003. Was working fine. Turned it on the next day, got no picture and a high pitched whining noise.  Please let me know what I should do to fix it.

If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB

RCA 20

sounds like the Power Transformer to me,  usually accompanied by a high pitch (almost inaudiable whine) and  sparks arcing.


This needs a professional repair..

RCA F31672ET No Power only a whining noise when plugged in Please help

Most likely you have a bad flyback transformer and shorted horizontal output transistor. The whistling sound that you hear is the power supply telling you that it has a short in one of the circuits it powers. Most likely the circuit mentioned above. Stargazer

Check for shorted base-collector junction on horizontal output transistor designator Q14401. Also coil L14401 going to base of transistor needs to be desoldered, scrape ends, resoldered. If horizontal transistor is shorted, real possible flyback transformer bad.
