IF IT WAS WORKING OK BEFORE CHANGING FLUID. YOU MAY HAVE SPILLED A SMALL AMOUNT ON CHASSIS. SOMETIMES IT IS VERY HARD TO SPOT.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive 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.

Sounds to me like you need a new control panel board which should run you about $150-$200 max! might be semi burnt out like mine was and that is what i had to pay not sure if this helps but hey ya never know :)

No pic but sound ok


This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence
