The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.
Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.
You either have a bad CRT or a Shorted Red Output IC/Transistor. One other possibility is if
someone turned the Screen Control down if it is accessible from the back of the set.
Hope this helps,
Simultaneously press and hold VOL- on the television and VOL- on the remote for 3 seconds. (Nothing appears on the screen - Parental controls simply unlock.)
You can re-enter a password via Lock Parental Controls, if you wish.
Is this set hooked to cable? Is there a cable or satellite box? When you press the menu button, do you see the menu on screen? Do you see anything on the screen, such as snow, or is it completely black? If the signal is OK and the TV has no picture at all, the red LED on the front of the set should be flashing a certain number of times. If the LED is flashing, the computer has detected a problem in the set and shut the picture off. If this is the case, there is no way for you to bring the picture back by pressing buttons. The number of times the LED flashes is the computer's way of displaying exactly why there is no picture. The set should then be serviced by a qualified tech familiar with Sony TV's. If the LED is not flashing and the menu comes up on screen, check your signal source. If you are using a cable or satellite box, that box could be bad, and if you are using RCA jacks, the yellow (video) wire could be bad or pulled out.
This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.
You can turn up Screen control in back of set on the High Voltage Transformer and see if you see anything like a thin white line going across screen. If this is happening then it's your vertical IC output gone. It will have to be changed and a 100uf@50v cap in the same area.
