SONY KDF-E50A12U TURNS ITSELF OFF AND FLASHES POWER LIGHT RED THREE TIMES CAN ANYONE HELP PAUL

the 4 blinks on that model are indicating the set isnt starting due to a problem with the fan,

Sir check the lamp of your projection if already damage, if damage replace the lamp and reset also the lamp hour meter. Remove the screws to open the panel labeled "lamp" on the back of the Sony TV. Remove the screws that hold the lamp in place inside the TV. Pull the lamp out. Let me know what is your observation to the lamp so I can guide you. Good day and best regards.

Four flashes means Vertical Deflection has failed.
You have a frame fault. Shouldn't be much, an IC at the most.

you might have some dust inside the light engine you should dust out your TV set and if you clean the TV and still have the same problem then I would say you have a problem with your optical block

Hello Abasama:
Ok so you have gotten other assistance and no luck huh..
First where did u purchase the lamp, Look at it and make sure its a phillips type lamp, Most sites will sell you a lamp made by LTI these lamps are of poor quailty and proformance. IF the green lamp light is flashing along with the red light, The green is in most cases the lamp light error indicator, the red one next to it is the Temperture indicator. first your need to determine how may flashes the light are indicating, You could have a Bad thermistor which is located on the lamp housing itself, its use to report the lamp temp back to the main signal board. But this error code usually gives 6 flashes and 5second intervals, and repeats ifself. I have an Ebook I wrote for these types of error codes which might help you. So this is what i want u to do.

1. First turn off television
2. In sequence using your orginal sony remote that came with the set, press DISPLAY KEY, 5 KEY, VOL UP THEN PRESS THE POWER BUTTON, you must press all 4 buttons within 3secs or it will not work. the set should come on with a dianostic mode menu, with options like Fans, lamp, lamp hours, lamp door etc.. some menus are different but all sony televisions uses these code to access the diagnostic screen. Next to the options are recorded error numbers the number of times a perticular error has occured. Example (Lamp Driver----------4, or Lamp door-----------1. this indicated that the lamp door has been removed once.
or Lamp Driver has either failed 4 times or the unit tried to light the lamp 4 times.. Just remember that the number to the right represents the number of times and error has occured for that perticular function. This simple menu should lead u in the right direction for solving your problem. One note i forgot to mention, the lamp driver error also could mean the lamp itself is bad and not the driver(Ballast). Also when you have solved your problem go back to the diag menu and hit the 8 key on your remote to reset all error options back to zero. to get out of the menu just turn off power with remote, you can do this first after you see what error is being reported the go back and see what it records to futher help you troubleshoot your set

Hope this helps, I sell the Ebook for 19.95 which shows you this procedure and how to replace your color wheel and so on..

Good luck..

Green light flashes 5 and then red light flashes 6

3 red blinks means th lamp door in not on. if you have installed the lamp door corectly and it still does this solder all three pins together on the door switch.
