Normally this kind of problem are cause by loose terminal of components in the circuit board at the end of the Cathod Ray Tube. It needs resoldering, see if theres any crack solder at the terminal of any components and do resoldering. That might help.

My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


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.

Shop repair in most cases.

I have a sony kp-53n77 rear projection tv i cleaned the lenses but i still have alittle to much red how can i clean up the color


Older projection set:

Not knowing exactly what it looks like I suggest two things: first in the menu look for convergence to see if it is off adjustment wise--it can be adjusted in customer mode to see if that helps.

Also either turn color all the way off (Black and white) to see what color the screen is with no color--if somewhat red you will need to turn the red screen control down--I can tell you where and how.

If screen is too red, red will be the prominent background color with color off or on.

Another easy way to LOOK is go to an unused video input---should only see "Input 1" for example in green and rest of screen should be black and not red to any degree.

Let me know with a comment here what you find.

Have you tried adjusting the red screen control located inside the front of the set? Usually behind the speaker grill. It is part of whatis called the control focus/screen block. There are 6 controls on this assembly. Be extremely careful high voltage is present. If you turn the red screen control and no red is seen onthe red gun , there are two possibilities. A) bad picture tube B)open filament connection on crt board. Scrivitron
