Red screen and lines, then TV shuts off automatically
The red lines, in a curved shape, started to appear a few months ago. Now it is getting worse. The television starts going crazy with red lines until the entire television is red. It makes a loud noise and goes into standby mode by itself. It did this a few times a row so we just shut it off.

Usually that is a sign that your red picture tube is ailing. However there is a chance that it can be adjusted out, at least buy you time worst case.There is a voltage control in the front of the TV, you have to remove the bottom front half of tv to get to it. Some Sony's have 2 screws hiding at the bottom of set in front hidden behind 2 plastic covers,others just have screws along the backside.Be careful there are wires to front panel attached so remove slowly and leave wires on just move it out of your way..Once you remove that there is a small access panel to take off. You will see the voltage control (small plastic square with 6 knobs) The top knobs are focus controls for each tube the bottoms are for voltage adjust. The far right knobs are for red.So you can turn the red voltage control SLOWLY to the left,this will reduce voltage.Reduce until you see the red lines disappear. If you go too far one way or the other with the voltage control the tv will shut down and you'll waste time readjusting and turning set on until it stays on. If you can't adjust it enough to get all the red out without shuting down tv tube is in too bad of shape.
it sounds like your IR board is going out, its easy to replace and is inexpensive usually about 10.00 plus tax and shipping, and very easy to install, its one of the few parts you can buy for these models outside of the 479.00 dollar control box.
ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN. PRIDAH
This sounds as if one of your convergence IC's has shorted out. There should be 2 large black IC's on a heat sink, probably labeled STK392-040. There is a small fuse next to each IC that looks like a small resistor. The IC that controls red-red-half green is bad, leaving the blue where it should be. Replace that IC and its fuse and your picture should return to normal.
they gona get worse to dead circuit, a small capacitor (problably in the neck board) is bothering you, get a tech now that he can see the problem, gonna be cheaper now....good luck
ps some times the picture say to the tech was going on
