Question about Zenith C27A24T 27" TV

1 Answer

Picture problems My 27' zenith suddenly started narrowing down to the point where there is only a small strip of picture in the middle of the TV. Sometimes if you shut it off it will come back to full screen but only for a very short time. I ahve had this TV for 10-12 years and I am wondering if it is worth fixing.

If the line goes across the screen you have a loose solder joint on the vertical output IC. I've seen this happen many times in Zeniths and a lot of other sets. If the IC is not loose then there is a loose solder joint somewhere else in the vertical circuit. These IC's are 10 - 13 pin chips that operate the vertical deflection on your set. I feel like a drop of solder in the right place will fix it! Stargazer

Screen intermittently goes black for about 15 minutes. sound continues with all other functions ok.


Your TV has some loose contact in the circuit board. Usually it occurs on the soldering of picture tube base board. After long use the soldered contact will get loose sometimes. This fault cannot be detected by normal multimeter test. The only remedy is to resolder all the suspected soldering points. You just call a tecnician for support. You can assure it whether this is the problem or not; by make a small hit my hand on the side or top of the TV set while the screen goes off. Never hit it with any hard material. Only use your palm.

Resolder the vertical deflection section. Change pump up capacitor if it has one...100uf is a typical value. Is the vertical output some flavor of LA783x ?? May need to replace. A model # would help.

The picture is jumping, sometimes the tv shows three of the picture.


The solder joints on the vertical output IC have cracked. This is a common problem in those sets and resoldering the pins of the vertical outpit IC will cure the problem.

Zenith 27 TV - screen jumps and suddenly turns off.


Sounds like you have a vertical failure, and is causing the power supply to shut down. A repair person can probably repair this main board in this set but it will cost more in time and labor to repair. So the right thing to do is replace the entire module. This Zenith was designed to replace the boards completely to shorten down time as well as labor. The board this set needs is a 9-02107 module, and is avail from http://www.partstore.com for 52.44 + shipping. I dont think you should attemp to do this repair by yourself if you have no electronics training or tv training. This is just so you know what you need and get an idea on what this will cost you to repair. Good Luck
