How can I turn the screen voltage up?

from description you are on the right track--screen con inside will either be on the crt circuit board or on the high voltage transformer, on or the other--lots of the older Sony sets when the picture tube gets weaker need this done.

White lines on the screen.sounds ok.picture is coming behind white line.

Lines means Screen Drive is overdriving, try adjusting the Screen control on the FBT flyback Transfomer, adjust it down. If that does not Clear out Problem then replace the CRT Board that is connected to Picture Tube.

Sony trinitron television , when you turn on it takes awhile for the picture to come up on screen and when it does the screen constantly blinks

Three possibilities
First it sounds like your Tube EHT ( Extra High Tension) power supply is failing.
CRT TVs need a high voltage around 30K for the tube to work. Whcih is generated in the set, if you hear clicking sound like arcking this will confirm it. Unless you are familiar with HV electronics you should not attempt to fix it since it can be dangerous.
Second possibility is the picture tube is failing.
Third possibility is there is some problem with the video circuits, to check this try connecting a VCR or a DVD to see if the picture is OK. If it is, the problem is in the video circuits.

Green screen and distorted picture sound is good but no picture

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Sony Trinitron, no picture, sound works fine.

There are potentially dangerous high voltages present inside the set even when unplugged, so caution is required. That being said, if you can solder, you may be able to resolve this. If the picture returns with movement, it is possible that the problem is poor solder connections. Try removing the back and sliding out the main board. Resolder any connections that appear grasiny or have rings. That may resolve the problem.

Keep us posted.

Sony kv-36fs10

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!!
