  • kassa4u Dec 15, 2008

    My television is two years old; it began to flash red and green two days ago, after turning it completely off for five minutes, then switching it back on it was fine. Unfortunately it did the same this morning and will not come on, even the fan does not come on anymore.

Sony bravia KDF-E50A12U rear projecion tv wont turn on


Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!

Manual for Sony KDF-E50A12U 50 in. HDTV LCD TV need a manual


If you are looking for an owner's manual, you can download it from the Sony website for free. The service and training manuals that show the circuit diagrams and exploded views, you would usually need to purchase. Sony has them or other 3rd party companies carry them too but usually charge you around $20-30.

My sony bravia kdf-e50a12u turns itself off


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..
you can email me at delhielectronics@live.com


Good luck..

Sony 50 inch KDF E50A12U switched itself off!


Does the on/off light flash green and red or just green. Is the light to the left of the on/off light on (this means bulb has definately blown)

Probable problem is that your lamp has blown. This can replaced quite easily, but costs about £100. Search google for xl-2400, there is also a video on youtube showing how to replace bulb.
