I want to be completely honest with you!"You will need a Projection TV repairman for what you have described to me.
But before you do ,if you can ,check to see if the cooling fan is coming on,if it is call someboby if it is'nt fix the fan,are you mechanically inclined? I can help you break the set down if you want. Thanks for asking! ,get back to me if you need to.
It's the lamp. I do have an article on this in my Tips & Tricks regarding lamps, but replacing the lamp is a sure fix. I hope this was helpful, best wishes.
It sounds like you may have a failing power supply. It could also be that a connecting cable from one of the PCBs is coming loose. You can try reseating all the connectors to see if that helps. As for the power supply, you may have difficulty troubleshooting an intermittent problem, and should probably refer a problem of that nature to a professional technician.
Good luck.
No solution for you...but I have the same problem. I also had the green blob problem which sony fixed earlier this year. It happens on an intermittent basis. Screen goes off, standby light blinks green, then comes back on. Its off for maybe 1-2 min.
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.
Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.
All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.
