Adjusting brightness


This is a fault called one color predominant screen. If red color is more than normal, and the picture itself appear in red, the fault should be with its video output stage circuit board. This board can be located at the neck of the picture tube, will be plugged directly to it. Check for any loose soldering to this board'w solder terminals.

Why do i have a green screen after i turn the screen adjustment screw?


since every display color monitors are only work with 3 primary color which are red, blue and yellow. You could also search it that by mixing these colors, you could get any color your want. Thats how color monitors work. Now in case of green color, it creates by mixing blue and yellow. When you are turning the screen adjustment screw, the red color plug will become lose, makes it appear green.
I hope your got the reason.

Kv32526 32" sony no picture everything else is ok can hear voices can change channels 1997


you should check the RGB, check the heater voltage from Fly back to the heater (CRT Tube), make sure there are about 5 VAC Voltage, if no damage is usually there at 1 ohm resistors, other than that the damage can be caused by any part of an abnormal color, RGB voltage not equal or one is weak or not functioning. in other words, the color Green or Red and Blue did not appear. consequently it will not appear on the screen image. the solution is to replace the CRT tube or CRT tube Recharge using special equipment recharging....

Is it my Convergance??


Do not try to align the colors with the remote. One of your convergence IC's has gone bad and needs to be replaced, possible burning one of the 3 low value resistors next to it. If you change the convergence settings now then they will have to be reset when the new IC is installed.

32 inch sony trintron tv red blue green


Switch OFF TV. Open rear Cover. Switch ON the TV. Now, very carefully, (There are very High and Dangerous voltages inside, also, use a mirror to see the screen) adjust a red colored box called "H.STAT" which controls the Horizontal Convergence of the CPT. Should solve your problem. Check some Vertical portion of a object (Text in some Video Title, wall of a building, etc, ) as a reference.

All red picture now.


Sounds like a bad capacitor or drive signal on the red tube. Could be the red drive transistor, or a cold solder connection on the crt board
