My 2002 big screen sony trinitron has a blinking standby/timer light and will not show picture or sound. I have never used the timer and the TV power sounds like it turns on but the screen is black. This just happened while I was watching it, was not gradual.
Ok. I think you'll need an IC or a PSU.
Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen slightly.
