I'm getting a bright green screen. I can hear the tv, just not getting a picture

check the high voltage with the screen control turned up high where there is no raster. suspect problem within the video circuit where there is no high voltage or defective picture tube.some time when the screen is black and the screen control advanced,you can see if the tv has video or vertical or horizontal problems on the screen.service the high voltage circuit if there is no raster or high voltage is seen.no raster can be caused by the no heater or filament in the CRT.---- a defective picture tube can cause many problems, such as, poor brightness ,missing colors,intermittent picture,poor focus,a single-colored raster,arching in the gun assembly,retrace lines in the picture,negative picture,chassis shutdown,noheater or filament lit and no raster to name a few.an open filament or heater can cause no picture or no raster symptom.a defective CRT can have an extremely bright screen.loose particles of the cathode element can lodge between the grids and cause an intermittent black and white picture. simply tap the ends of the CRT gun assembly and notice if the picture begins to flash off and on.---- with a leaky picture tube after turn on the raster dims and get extremely bright.a dim picture with no green in the raster can result from a bad green assembly. a heater-to-cathode short can cause a raster to change colour or a result in no raster at all.replace the picture tube if there is severe arching in the neck of CRT. excessive brightness with retrace lines and a vertical collapse to a thin line can be caused by a bad coil on the neck board of the picture tube.rejuvenate the picture tube when there is very bright green screen. check for the resistance change on the resistors of the CRT neck board for an excessively bright picture with retrace lines.excessive dust inside the CRT spark gaps within the picture tube socket can cause the very bright raster and the chassis shutdown.a defective video amp,luminance buffer,or reference transistor can cause a bright picture with retrace lines. -------- for getting any required parts to replace you can get it from www.radioshack.com or from www.partstore.com or from www.shopjimmy.com --------- thanks.please do rate the solution.thank you for using fixya.keep updated.

check on vertical ic supply is it 24vdc otherwise try to replace the ic first

There are 2 possibilities of green screen in this model.
1- Driver circuit of green gun is defective. 2- Screen itself is defective.
Now I want to know, do you have TV repair experience and basic electronics knowledge to test and check above 2 sections in TV?

i have the same problem picture is blue/green with blue and green arched horizontal lines

no picture at all only sound then tv shuts off after 5-10 seconds and then a bright blue flash in the center of the screen

have tried adjusting the voltage screws didnt do anything

It can be a result of dry solder joints on the CRT base PCB, the PCB you see on the end of the CRT. Resolder all the joints on that board perfectly and thouroughly and this will be alright. Good luck.

Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider

Sounds like the green tube is shorted.

Is the green really bright with small white lines in the screen?? If it is its probably a shorted picture tube. That is if you still have sound. If you have no sound its probably a power supply problem in the sweep section of the set. This is not a repair for a consumer to do as its a solid state set and there are no user serviceable parts inside these sets. Get a service person to assit you with this repair. Good Luck

if the screen is real bright green with thin small white lines in it its probably a shorted picture tube. Or a shorted Green driver Transistor. Good Luck

Check and make sure you are on tv not video. Unplug and replug all the game systems or other things you might have plugged in your tv. And if those don't work make sure you are not on input channels (input1, input 2, and do on). If still you are having problems go to the tv menu and and make sure you are on antenna if you have a antenna or cable or satilite if you are on one of those. I hope this helps!
