RCA 27'' TV will not turn on.

A number of possible reasons for this---failing part in set or even bad connections on main board in the set----model listed is prone to going dead with high pitched squeel etc.

The deflection board will need to be replaced. You can get replacement deflection board from www.tvrepairworld.com

My rca purflat doesn't turn on with the remote, batteries are good, it however turns on when I press the power button and then the channel button.

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

Not Picture and not sound

sounds like fly back failure. high voltage transformer

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.

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

 

This needs a professional repair..

 

 

that high pitch is comming from the flyback replace the flyback and the HOT.and you will restore back the life of your tv.good luck.

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
