Green picture tube fluid

The green piture tube is low on fluid and displays a vertical line on the tv screen. Where do you buy the fluid and how do you replenish the chamber? By what name do you buy it? By the way, the vertical line appears red on the screen and I was able to see it on the green picture tube. It looks like a scratch behind the fluid, viewed from top.

Green line in middle of tv when switched on


Is there a picture with the green line going through the centre. If it`s just a green line with no picture, it sounds like the Frame (Vertical scan) Output IC has failed and possibly the safety feed resistor near the LOPTX. The reason why it`s a green line is to protect the tube from phosphor damage. The older TV`s would produce a VERY bright white line across the screen which could burn the phosphors withing the tube if left turned on in that condition. It`s not an expensive repair, but is it worth it with the price of Modern TV`s nowadays. If there is a picture with a green line, it may be due to phosphor damage, in which case, it`s a new CRT (tube). Ian

Vertical jitters on picture - JVC AV48P776


What you are experiancing is loss of High voltage. The line is called a retrace line. It is usally caused by failure of the flyback circuit or aging of the TV tube. This is the single most common failure with CRT based display systems. The high voltage can be tweaked up, to accomidate for the age of the tube. Its a short term solution. Because of the high voltage nature of this circuit, suggest a professional repair.

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

Black screen with green smiley face


If your tv has a picture tube,your problem is in it. If you have only one line now,the vertical circuit is not working. You could have jarred something loose around the picture tube.Maybe a yoke lead ???
