Power supply is probably going out. Not likely the video card in this case.

Horizontal white lines on TV screen, all channels. I have tried to adjust everything through the menu button.


The picture tube is been over-driven by an open resistor on the video board, a quick fix is to slowly turn down the high voltage screen control on the fly-back transformer ( one is focus "don't touch" and the other is marked screen "turn anti-clockwise" until lines just disappear.

When you turn the TV on the screen splits in two,


it sounds like one of your buffer boards are going bad. these are the boards that help put the picture on the screen. there are 2 boards an upper and a lower board. if you remove one and turn the tv on you will get half a screen. see then if you get the lines. please leave rating after you check.

Red picture tube needs screen voltage adjust. Open fornt or back of TV and look for a black square looking box with adjustment knobs. Look for red screen adj and slowly turn rt or lft until lines just disappear. If screen goes too bright tv will shut down, just turn back on again and retry

Pink/green bar at bottom of picture


phillips are known for dry joints so i would check this first ,if you are good with a soldering iron.

visually inspect each pcb for poor solder connections and solder any bad ones that you find.

this should do the trick.

The screen turn completly red after about 20 min being on


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.

Hi, your vertical section is beginning to fail, from your description you have a few electrolytic capacitors that are beginning to go bad, the correct term is they are "leaky", the set can be fixed easily by a tech, not so easy for a layperson because you don`t have the service manual or a capacitor analyzer. NOT an expensive fix, tech will have to remove board, unsolder some caps, check them and replace the bad ones, do a little touch up solder work and set is good as new, any questions? feel free to ask away, if not Happy Holidays, BMW Rider

Picture and sound disappeared


your red crt bulb is starting to go bad. somtimes you can tap lightly on the neck of the red and the prob. usually short term will go away. if not tube replacement is necessary. this is sometime a pricey repair. but worth it! john
