It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen. Do you see standby red light blinking when TV shuts off after showing blue image for a while? If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution. Thanks.
tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.
I had this problem and at the same time I was getting blue tint. When the blue got darker, this would happen, Adjusted the voltage on the guns (3 screws in the front - lower panel off) and the blue went away and it stopped turning off. But later, it would start all over again. Same procedure, same fix.
FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,
try turning up screen slightly.
Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.
