Magnavox TS2560 B101 vertial hold shot?

I have a Magnavox TS2560 B101 tv that one fay went screwy with the vertical hold (wavy lines from top to bottom). I noticed the picture on the screen was bigger and did not fit the screen. When the TV is on a channel which is bright the vertical is fine, but the picture is still enlarged. When the channel goes to a darker picture the tv's vertical goes haywire, but then clears up when it gets bright again. Is this something that can be done at home with a minor tweak or is this a "take it to the shop" type situation. If it has to go to the shop, what is the range of cost for this repair going to look like. Thanks.

SOURCE: white line horizontially through middle of picture

A repair like this is in the vertical drive/output section of the TV set. It could be a simple capacitor causeing this problem or a combination of the capacitor and the output IC. A repair like this should not exceed 120 to 150 US. Is it worth that to you? How much can you replace it for? Good Luck PS please dont forget to rate this thread.

SOURCE: Tube TV - one thin horizontal line of bright light

Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.

SOURCE: No Picture Has a bright horizontal line with off white & gray vertical bars

The Problem Philips 27TS54 c101 27B800-7562 White horizontal line in the center of the screen. Color is present in the first half inch of the leftist corner of the horizontal line.
Audio is present and controllable. The green power led from a cold non plugged in state remains solid until CRT goes to ignite. A click is heard then the green power LED blinks.

Possible Answer Posted by PEE_WEE 4/28/2005
On the CRT circuit board(picture tube), you will find R3340, which is a 10 ohm 1/3w resistor. The location of the resistor is printed on the bottom of the ckt board. It is burned open, replace with a 10 ohm 1/2w resistor. This will solve your problem. The original resistor was sized too small, should have been a 1/2 watt. This resistor is mounted standing up on ends. Mount the replacement resistor the same way. Be careful and don't get the circuit trace too hot and damage the circuit trace. (it's very small) The resistor is located on the crt(cathode ray tube), pcb(printed circuit board) socket. The resistor supplies apx +200v to the collectors of the r, g, b, video driver transistors. If this voltage is low, it causes excess brightness(excess beam current), causing the set to "shut-down". If the shut-down is too quick, you will NOT see the excess brightness, because the picture tube has not warmed-up enough to display anything on the picture tube. To see if the set displays "excess brightness", you will need to turn the set "on" about 5 to 10 times. This will heat the picture tube enough to display "excess brightness", IF that is the PROBLEM. Of course, there are OTHER defects that will cause a tv to shut down. There are built in safety circuits, that will "activate" if excess voltage/current or heat is detected anywhere in the set.

NOTE
My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008

SOURCE: CRT TV with only a horizontal line through the center of screen.

Hi,

Yeah. Unfortunately you are right. It is normally the ic that controlls power to the gun. And it is expensive.
Your only chance is to find another model of the same TV that some is ready to trash or throw away at low cost and that TV having some other defect. Advertise in the local newspaper or other channels. It is worth a shot.

No, it is most certainly not worth fixing. In fact, it is worth nothing - even if it were working great. Probable cause: an obsolete electrical component. Cost: no TV tech will touch it. Sorry. Suck it up and buy yourself a moderately priced TV.

Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

Wavy lines


Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.

Magnavox 25inch TV picture problem


That's a vertical deflection problem and is probably caused by a capacitor going bad in the vertical stages or the power supply stages that supply the vertical IC . And you're right, as the cap dries out more, it'll only get worse.

There is a company called PTS Electronics that rebuilds main boards and sells them on an exchange basis. You might check into that, but you really need to have a little knowledge about that stuff to install a main PCB.

You'll need the part number off the board.

Hope that helps...

Wavy lines


I have the same problem with this tv. i took it to a tv repairman, and he told me my convergence circuit board was the problem. the circuit board itself is about $300 and the labor to fix it is another $150. So i never got it fixed, cause it's just too expensive.
