SOURCE: fuzzy picture

You can't make SD look like HD thats why HD came out, the best you can do is adjust the picture controls to get the optium picture

Depending how long you have owned it and if a Lamp was ever replaced, it probably needs to be replaced. You can check with SONY at
1800-222-SONY and see if they could sell and send you one.
Hope this helps,

SOURCE: 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..

Good luck..

Check your lamp door, it may be warped.

SOURCE: is it an easy fix to replace the bulb on a Sony

Indeed it is easy to replace the bulb, unplug the TV first, simply remove the outer cover door, then you need to remove the protective inner door, simply place your finger in the ring pull and lift gentley up and pull, when you have the replacement bulb you need to remove the 2x screws on each side holding the fixing brackets then remove the screw that is located at the bottom where the bulb wires are, once removed then you can remove the casing, undo the retainer bracket screws for the bulb and also disconnect the wires from the bulb, DO NOT touch the new bulb with bare hands you must use rubber inspection gloves as your skin oil will damage the lamp, fit new lamp and re assemble housing and re-fit making sure you rerplace the inner door correctly.
