Hi,

Your posted/describe symptom seems to be that the green color drive is defective. The "lines going across" are flyback retrace lines brought about by the safe problem.

The corrective procedure would be to replace. In most TV units, color drive are three (3) identical transistors: for the blue, green and red. They are normally located at a small squarish PCB attached to pins of the CRT right at the rear end of the neck. More often, they are heatsinked. Repair should be a straightforward desoldering the defective component and replacing with a new one.

In some versions, color drive is a single IC power pack.

Still, it is also possible that the problem may be due to cold solder on any or all of the pins of the above describe transistor (or IC).

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

Good luck and kind regards.

I tried to fix my tv and accidentally hit v- something (last page of service menu). Now There is a horizontal green line in the middle of the screen. How Can i fix it?


V stands for vertical output. You have a vertical collapse. Go back to service menu, and set range for vertical. Or you can try factory reset.

I just purchased a universal remote and programmed it to my Apex and I can't get the cable to work I can't get it to go off mono what do I do?


Make sure your TV is set to Cable (Manually), Then with you TV on, hold the cable button down, and keep pressing the power button, till the TV shuts off...this should set your remote to cable mode! When you turn back on, press cable button then power!

You may have to repeat the steps, for the TV to come back on, to re-program your remote!

Hope this Helps!

When you select "CCD/Text Off ", the CCD / Text function is off.
3)Press the CC button to turn on/off the CCD/Text mode
OK.

Single green line spanning across the screen horizontally


I was just watching TV and all of a sudden the screen minimized down to a single green line spanning across the screen horizontally. The label in the back says it was made in 1996 so it is an old tv. Can anyone help?

It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer

Can't see scrolling text or sport scores


Here's how to fix it - I have a PF 2425, and it's driven me absolutely up the wall. Videogames are useless because you can't even see the crucial gauges etc. Likewise, subtitles and credits in films are cut off. it's ridiculous, especially considering how easy it is to fix (if you know how).

1. Decrease volume to 0.
2. Press MUTE so the tv says "MUTE" onscreen.
3. Hold MUTE on the REMOTE and MENU on the TV simultaneously until the service menu appears.

It's important not to screw around here too much. Use your arrows on the remote to navigate, the first option likely will say "MENU.0" or something like that. Use that to flip through the pages. What you're looking for are values like V Zoom, V Scroll, etc. Same goes with the H values. Toy with these a little and you'll be able to get the tv scanning perfectly.

I can confirm this worked for me! So good luck.
