Question about Zenith C27A24T 27" TV

1 Answer

Vertical height shortened on 9-1074 module.

So far I have found two bad capacitors on this module, C2109 a 2200uF/25V and one other I didn't write down. The connections on the vertical output IC are good, and I don't have a print (Sams 3002) for this set available. The picture height is about 6" on this SJ2771W model TV set. Any ideas?
Thanks,
Bill N3EVG@aol.com

    The picture height is about 6" on this SJ2771W which translates I guess to insufficent vertical height, usually a common problem involving defective capacitors in the vertical circuit. I have checked all I could find around the vertical section, and replaced two that was high in ESR (one was leaking out the bottom of the electrolytic) but suspect there is one I may have missed as I don't have a schematic on this set. Could be a resistor changed in value as well. Was hoping someone could shed some info on this.

Hi Expert, I have the CT-27G13 and it has the thin horizontal line of light running across it. Can you tell me how to fix it?


This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical. Be sure to vote/rate me if this helped Thanks!
In this case the vetical o/p IC is LA7838 and the IC is located at the right front corner of the PCB (main)the 2 capacitors are- 100uf 35V and 220uf 25V.

Yes there are 2 capacitors that are usually bad one they are both very close to the vertical output. one is a 100uF at 35Vor 25V and the other is usually a 220uF at 25 or 16V- Replace with 100uF at 50V and 220uF at 35V- and observe the polarity(+,- symbols on caps) before replacing.

Needs vertical height adjustment


Is the picture stretched or shrinking and is it distorted or have lines? There are no vertical Height adjustment the circuit is prest and there is likely a problem in the vertical o/p circuit.

Is there a vertical height adjustment on the Toshiba 27A3. Thanks, Ian


yes there is but there are 3 capacitors in the vertical circuit that go bad causing a height problem,white lines on top,or a very small height. change the capacitors in the vertical section.the yoke on the back of the picture tube has 2 coil sets on it,one is horizontal,and the other is vertical.the connector next to the flyback transformer is the horizontal. follow the wiring from the other connector and it will take you to the vertical drive ic located on a heat sink.the three capacitors go bad because of heat from the heatsink cooling the vertical drive ic.

TV vertical height-Mitsubishi Model CS 35505


If the height has dropped down, you need to first find out why. Most likely there is a bad capacitor in the sweep power supply or the vertical output section. Good Luck
