Will not turn on

Was watching TV when all of a sudden the screen went black and turned off. Now I have a red blinking light under the Timer-Stand By. I try to turn it on (I hear the click) but I also hear another click (turning-off) a second after. Will not turn on. Sony's operating manual says "Your projection TV may need service" ?

Re: Will not turn on

I have the same problem. The red light blinks slowly for several minutes. I had a Best Buy tech look at the set and he claimed it needed a picture tube at the cost of $1,000. I don't believe his tech was being honest and I think Best Buy is just trying to sell me a new tv.

How many times does the light blink? There is a diagnostic set-up built into these Sony TV sets.

TV turns red,shuts off, stand-by light blinking 8Times

Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

When you turn the tv on the red light on the front(stand by/timer)flashes and the tv starts to come on and then it turns off.

Do you mean the screen turns on briefly or the stand by light just keeps blinking. If the tv turns off after switching on then it probably means a protection circuit fault. Also please provide me the number of times it blinks before it pauses. Awaiting your resposnse.

Tv wont come on and a red light is blinking. I have a Sony Wide screen projection TV model kp-46wt520

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

Sony rear projection screen is red then tv shuts off

Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.
