Big screen sony tv goes green after 15 minutes. I am pretty handy taking things apart and know how to solder so if I need to get dirt I can. Any good positive solutions would be very thankful. Thank You

here is what you need to do:



You will have to remove the entire large plastic grill/plate on the front of the set beneath the screen.

It will be secured in one of two ways= some have two slightly hidden screws on the front near the bottom (one on either side) with a little snap out plate that covers them=if this then you pop out the covers and remove the screws; the entire front will pull out from the bottom and has hooks that engage at the top, pull out from bottom and let the hooks come clear.



The other version has up to six screws on the back (some on each side) and removing them will allow removal of the entire grill.



Note that their is a control panel attached that does not need to be removed; some of the wires are extra long and dressed= you can loosen them enough to turn the grill so the left side is facing down and to the left.



Behind the grill in the middle is an fiberboard inspection plate. Remove it and look inside.



Allmost dead center you will see a two and a half inch square black block with two rows of controls.



You need to look very carefully as one row left to right will be Focus(don't touch those).

The second row will be SCREEN and Green will be the middle one(you should be able to see r,g,b next to each control but they can be hard to read as the entire block is black).



The idea here is to try to turn the green screen down. Best way to do this is with the set on a blank video input take a look at the screen= all you should see is the input number and if you see some green or a faint curved green line turn the green screen slowly to the left until it JUST vanishs.



Since you have to do this with the set on be careful not to touch anything else except the plastic control!



The set will shut down if any of the three picture tubes does this as it detects too much current is being drawn.



Let me know if you have Questions before you attempt it.
