You need a new green CRT. The lines were retrace lines which are the first sign of a tube developing a short eventually the green will short completely and cause the set to shutdown.

I have green arched =lines r=going through my screen How do I fix this?


If the lines are slanted up from left to right and spaced several inches apart, you are seeing the vertical retrace line. In that case, you may want to turn down the screen voltage on the green CRT. The instructions for making this adjustment are given in the service manual.

It should take just a small tweak to hide the retrace line. If adjusting the screen voltage won't do the job, check for a leaky or improperly biased CRT driver transistor, then compare the video waveforms with one of the other CRTs to make sure the voltage at the vertical blanking interval is correct.

In the worst case, there is a problem with the CRT. This is generally accompanied by occasional arcing (bright green flash or the set shuts down with an error code flashing on the power light).

Hello: Have you tried to adjust you Green Screen control on the focus block assembly. located behind the front panel assembly. Here is a solution that might help you, turn off the green by turning off this control, make sure u look at the block and make sure you are not turning the green focus knob instead of scrn crl. Turning the control slowly to the left the retrace lines should disappear as the green video darkens. Then turn the control slowly to the right just until the retrace lines reappear, then turn back slowly left just until the lines go away. If the screen is Blanking on green tube only then you have a video blanking problem on the main signal board. Or possibly a IK bias problem. It is also possible that the green CRT is defective. The FBT is not bad because the screens are lighting up indicating you have high voltageand heater voltage which is derived from one of the secondary windings of the FB. If it is a Blanking problem i would look into replacing the A Board assembly.

Sony KP-51WS500 projection tv. Screen is green with curved lines


The green picture tube has an internal short. Happened a lot with that model. The tubes are no longer availible. But a reputable company called Video Display will rebuild the tube completely. But the tube must be pulled and shipped to them. Most repair shops would charge around $400 to $500 for the complete job.

Flashes blue and then the tv shuts down


The tech is correct about the internal short inside the blue CRT. There is a way to remove that short by applying a small amount of current to burn the short but that might damage the CRT even more. At this point the CRT needs to be replace.
I will post the instructions on how to remove that short but you will need to have a good regulated power supply and limit the amount of current to 1 to 2 amps.
