Question about RCA F27442 27" TV

2 Answers

Rca f27442 My television has no picture or sound. It makes a whining sound that won't stop until the tv is unplugged. When I plug it back in, the whine starts again. I left the tv on one night and woke up with the noise and no picture. It hasn't worked since.

You may be able to get by with just a new Horizontal output Transistor location Q14401 after repairing the coil L14401 connection. I suspect the repair would not be worthwhile if the high voltage (flyback) transformer is bad as well as that part costs about $50.00 by itself.

Re: rca f27442

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.

No picture but has sound

Coil L14401 is not making a good ground. Remove him carefully, scrape the ends clean and the board where he was removed. Now reinsert and resolder this little guy,and Bingo you have your TV back. This is a common problem with your TV! Thanks for asking!

The TV does not have a reset button. If you have no picture and no sound, there is something wrong with the chassis. In this case the set should be serviced by someone experienced in the RCA CTC203 chassis. If you have no picture but do have sound, then it is possible that the 2 controls in the 2 little holes in the back of the set are not adjusted correctly. This is quite possible since you said you put a screwdriver in there and got a fuzzy picture. The control on the bottom is called "screen" and is the overall brightness of the picture and the control on top is called "focus" and is the sharpness of the picture.
