Question about RCA F36668 36" TV

1 Answer

Color is all red - picture hard to see

The TV powers on but the screen is completely red and it is hard to see anything. Adjusting the settings in the Menu does not help any.
Not sure if it needs a new picture tube or something else.

Bought a new TV since it wasn't worth it to fix the old one.

Picture has red tint


I would unplug it from the wall for a while and see if that will help reset it. Also make sure there are no magnetic devices near the screen because this will change the screen color as well. Mine will mess up every once in a while so I just unplug it while I am off running errands, plug it back up when I come home and it seems to reset itself. Good luck

The tv is at least 17 years old.The blinking red light blinks 5 times ,then the tv picture goes off . The voice is still on


Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.

To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.

There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.

Tv keeps turning itself off and the white in the picture looks alittle off.


To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

Zenith TV has me seeing red.


The red gun in the picture tube itself is shorted on. You will have to replace the picture tube itself to fix the problem. Probably want to just buy a new set. Sorry!

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

F25216bc RCA 25 inch TV. Color is distorted with a heavy red tint


You either have a bad CRT or a Shorted Red Output IC/Transistor. One other possibility is if
someone turned the Screen Control down if it is accessible from the back of the set.
Hope this helps,

TV shows red


It sounds as though the color settings have been altered or that the tv is going out. Assuming this is a crt unit, you might try adjusting the color or unplugging it for a few minutes.

Good Luck,
