Question about RCA TruFlat 27F520T 27" TV

1 Answer

Our 2004 rca tube tv screen went recently went out on us. When you turn on the power, you can hear the tv and you'll only see a blue line in the middle of the screen that shrinks and fads out and the tv eventually turns off completely. We cannot see anything on the screen besides the blue line and only for about 3 seconds. We would like to know how to fix this in the cheapest manner possible. I looked online before and it said something about the tact switches possibly needing replacement? I'd also like to do this myself. Is this a common problem? If it is the tact switches, how do I go about ordering these and how much are they? Thank you, Ryan

Hello
It is reparable problem. You see a blue line across the middle of the screen I thinks and posts this solution. The fault is due to the absence of vertical scan. In your set, there is an IC used for this purpose, and it has been dead short now. That is why you see the line at the begining, and it disappears a few minutes after. The vertcial output IC can be located at the main printed circuit board, usually screwed on to a metal heatsink to sink away the heat genereted in it while working. You can easly located it by the following method.
Look at the deflection coil, the coil fitted at the neck of the picture tube. From which, four wire will go towards the printed circuit board, and will be pluged on to it with socket. Just draw out the printed circuit board from the TV and turn it upside down. Look for the connections that I have menttioned earlier, four of them, out of which two of them will be for horizontal scan, and two of them will meant for vertical scan. Follow the vertical scan track, can be identified by two wires emerges form the board, will be connected via copper track and will go to the vertical section, from which you can identify the vertical IC fitted neareby it, usually will have 7 or 9 pin vertical type one.
There is no need to check it now, because, it has already been shorted and damaged in your TVs present case. Desolder it out from the board, and go for a new one of same type and number, replace it as the previous IC was, will solver your proble.
You must have a desoldering pump, a soldering Iron, solder wire, some knoledge in electronics,and more comecentration and patience. OK.

How to hard reset rca 27F554T


The means the deflection is not working, there is a coil of wire around the neck of the tube, it is run by a transistor. This transistor has probably gone bad

Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.

RCA D52W20 - turns on and off, blue screen, tech said need picture tube


It very well could be the Blue CRT shorting out. However the not shutting off is not a symptom of the tube being shorted that sounds more like a signal board issue rather than a picture tube, as the signal board can cause all the symptoms you have described.

Blinking red power light - set will not turn on


Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.
