Question about Zenith C27A24T 27" TV

2 Answers

Everything red is on fire with an ugly pink shadow!!

I have a Zenith A27A11D TV and recently the reds (anything red) has a firey glow to the point where the TV is not even nice to look at. The glow surrounds the reds and obliterates everything else. I have toned down the color manually a bit, but naturally now everthing is washed out. Any suggestions as to what this could be and if it's something an everyday joe like me could attempt to fix? What part would I need to buy and where should I look for it? Thanks, Todd

If its a projection style 3 guns.Its worth a try remove the cover and access the focus box and adjust the dials (2) marked R.Only do this if you feel confident and switched on the convergence mode.

Todd, The fault could be in the red video amplifier circuit, and would require either a service sheet with voltages to measure, or an oscilloscope to observe waveforms and levels. It may just be faulty, noisy preset potentiometers on the circuit board, used to adjust various parameters of the colour system. If you are confident then go ahead and check these circuits. Another cause could be a fault in the CRT (cathode ray tube), or the magnets used for alignment. These require skilled knowkedge of what they do and one may have shifted.

I have an old Zenith SY2568S that hasn't had a crisp picture in a while and has just recently developed a translucent white picture. Everything else seems to be fine. Can I fix this on my own or should I...


This is caused by a device on the television called the "flyback". It is the most dangerous part on the TV and should be set by a trained technician. What is occurring is the flyback is going in and out of it's correct setting by the device that sets the voltage output of it. It is called the Focus Foyer or similar flyback control. Take it to a technician. Have him give you an estimate - I usually set the cost of repair to 50% of the original cost of the unit - beyond that it would be cost INeffective. Hope this helps

I have a glow or a shadow around everything I watch...I tried the converse blue but i dont know if i did it right bc it didnt work...how can I fix that?


CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Picture shadows...color (red) seems to be out of line


HELLO MY FRIEND. YOU PROBLEM IS THE CONVERGENCE STKS, WHEN THIS IC'S ARE BAD YOU HAVE NO CONTROL OF THE CONVERGENCE ADJUSTMENTS BY REMOTE CONTROL,IF YOU OPEN THE SET LOOK FOR TWO BLACK PARTS WITH SAME SHAPE AND NUMBER.YOU CAN BUY THIS PARTS ON LINE AND REPLACED THEM PRETTY EASY IF YOU HAVE REPAIR SKILLS AND ALWAYS REMEMBER TO UNPLUG THE SET BEFORE YOU DO ANYTHING.
YOU WILL NEED A SOLDERING IRON, A DESOLDERING TOOL AND SOME SOLDER, YOU CAN GET ALL OF THIS THINGS AT RADIO SHACK.IF NOT CALL THE REPAIRMAN HE SHOULD NOT CHARGE YOU MORE THAT $250.00 FOR THIS JOB WITH PARTS INCLUDED.
GOOD LUCK

No Red- Intermittent


Hi,

A short answer, YES. I suspect a cold solder on the red drive transistor. That transistor is one of 3 identical components (one for each of the blue & green). They are normally found in a small squarish PCB that is connected to the rearend of the picture tube. In some instances, they are also heatsinked. More often you need to remove the shield/screen protecting the foil side of the PCB. This has to be done gently since it can easily crack the glass holding the pins.

Cold Solders are corrected by applying heat from a soldering iron and probably a dab of solder lead. Solder joints should be shiny (not dull gray) with no air bubbles.

If your concern has not been corrected after completion of the above procedures, you may need to replace the red drive transistor. it might also be worth your while to check for any other component that may suffer from cold solder and/or any loose connection(s).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.
