Locked TV have no remote, tv won't turn on


You're going to need the remote to fix this one. If you have any other GE or RCA tv's you can try it. Most of the remotes that are produced within a few years of your television will probably work. When you get one the instructions are: Front Panel Lock This feature allows you to lock the buttons on the front of the TV. Even when the front panel lock feature is on, the TV operates with the remote control. To lock the buttons on the front of the TV: 1. Make sure the TV is on. 2. Press and hold the POWER button on the remote for approximately 5 seconds. To turn off the front panel lock: 1. Make sure the TV is off. 2. Press and hold the POWER button on the remote for approximately 5 seconds

Rca 27410tyx1 will not shut off


Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

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..

Squeak


The high pitch squeal you hear is usually caused by a coil vibrating, normally in the horizontal circuit. I've also seen the ferrite bead on the horizontal output transistor do this, but, it is rare. I normally will repair this by finding the coil and "tightening" it. To tighten a coil, technicians use different chemicals, such as, a hot glue gun, rubber silicone or even finger nail polish. I will find the coil that screams by starting with the usual suspects and using a wooden dowel, barely touch the coil and if the pitch of the noise changes, then, thats the coil that needs repaired. If you do not know your way around the inside of a television, I never recommend you do so, since, this procedure must be done with the set turned on and you poke your hands around the inside of the set by the high voltage circuit. Hope this helps your decision.

TV won't stay turned on, no picture, started making high pitched noise


That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer
