I have a 46" Sony bravia kdf-46e3000 that keeps turning off after 1-2 mintutes of viewing and power light blinks afterwards but never turns back on. Any suggestions to what could be wrong with it and how to fix it?

Call it in for service. You have a power problem internal to the TV and something is overheating. Unless you know how to fix TVs you probably can't fix it yourself.

We too have the same model 46" Bravia and recently were faced with the same symptoms you noted. Can you confirm that once the screen goes dark and all sound stops that the green power light eventually stops and the red LED LAMP light blinks? If so, per page 43 of our User's Manual, Quote:
...the projection lamp should be replaced when the red LAMP LED on the front of the TV blinks.
While the manual shows the lamp is easy to replace, this part is not cheap so I recommend a google search for your best deal. You'll be surprised at the price range available.

I didn't know that this was a projection TV when I initially responded.
My diagnosis still stands from a general perspective. Thanks for posting a more specific diagnosis.

Just ordered a new XL-2500 lamp plus housing for our 46" Sony Bravia online from projectorquest.
http://www.projectorquest.com/product_info.php?products_id=4363
Total cost: $167.75 including 2-3 day USPS Priority shipping. By far the best deal I could find.
Takes less than a minute to remove 2 doors and pull the lamp housing... less than that to pop it all back in. (Carefully cleaned the dust from the housing region and practiced with the burned out one while I await the new arrival.) One might consider acquiring a spare as these do eventually burnout (1-2 years / 6,000-8000hrs) and it appears Sony no longer manufactures this particular television.
Also, after the lamp is replaced, the power cord plugged in, and the TV turned on; the Users Manual indicates the need to set the Lamp Replacement option in the General settings (see page 42). This setting is necessary to inform you when the next lamp replacement is needed.

XL-2500 replacement lamp from "projectorquest.com" arrived promptly and well packed. Lamp took mere seconds to replace and about the same to reset the 'Lamp Replacement' option under the 'General' setting to provide an on-screen visual indicator prior to the next time the bulb needs replacing. In a minute at best the picture was even better than before and I now had the comfort of knowing such an item was safely owner serviceable.
Also worthy of note, projectorquest even addresses lamp recycling by providing a postage paid return label for return of the burned out mercury lamp and housing. Once used lamp is received with original housing, a $10 refund will be credited back to our credit card.
Hope this gives hope and a measure of comfort to others who may be dreading the repair of their 42" Sony Bravia rear projection screen TV after a few years of service.

Thanks as well. I now know to keep my nose out of questions regarding DLP TVs.

I have a KDF-50E3000. The lamp light isn't coming on for me. The TV will power on. I get light and sound for about two minutes, after that, the power light blinks. I can't get an on screen menu from the TV or anything. If I power off the TV for a few minutes, I can power it back on and get the same results.
I'm assuming some internal components are overheating. I can see a fan from the back, which does turn on and spin. My TV is 18 months old, and thusly out of warranty.
I have fixed my PS2, PS3, and original X-Box by tearing them apart and figuring them out. I also do PC repair for a living. I'm considering tearing the TV apart and trying to fix the power supply. However, I'm trying to see if I can find information on what the blinking power light means first.

enderandr, hijacking a member's thread is a forum rule no no so start your own thread about your own problem.

Sony considers the KDF-50E3000 and the KDF-46E3000 so similar the user's manual is actually the same for both models. The symptoms 'enderandr' describes appear the same as noted earlier in this thread. While not an electronics technician by any means, it is still my belief this problem is bulb related vice power supply. Pg 19 of the manual clearly describes the three LED lamps resident below the screen and just to the right of center. I first noticed our problem when the picture and sound suddenly went off and the green power LED simply blinked green instead of a steady green as normal. Once I read the manual regarding lamp replacement (pgs 43-45) I decided to pull our lamp out and then put it back in it to see if it might simply be a contact issue. Once I did this, the red lamp LED began blinking and then remained on which I interpreted to mean the lamp was due for replacement.
With this said, I would encourage 'enderandr' and any other Bravia owners in the 2 year timeframe that are now noting these symptoms to refer to this paragraph on pg 43 of the user manual. Quote:
The projection lamp, like all lamps, will eventually lose brightness and functionality, which affects the overall performance of your TV. How long the lamp maintains its brightness will vary depending upon your usage and environmental conditions. To maintain the quality of your viewing experience, Sony recommends that you replace the lamp (1) after approximately 8,000 hours of use; (2) when the screen becomes dark or the color looks unusual; (3) when the LAMP LED on the front of the TV blinks; or (4) when the lamp replacement message appears on the TV screen.
While ours never initially exhibited the exact symptoms noted in the manual, once I took the lamp out and put it back in, the red LED LAMP did light up providing me enough evidence that the projection lamp was burned out. As noted earlier in this thread, projection lamp replacement resolved our problem and was very easy to do with part in hand and following the guidance provided on pgs 43-45 of the KDF-46E3000/KDF-50E3000 user manual.

Thanks. I'll try reseating the lamp and see if the lamp light comes on.

Sounds good. Afterwards, if you believe your projection lamp to be the issue, please note the link to the site where I acquired our replacement lamp earlier in this thread. If you go this route, remember to set the 'Lamp Replacement' option under the 'General' settings once you've replaced your lamp with a new one. Doing so should provide for an onscreen indicator next time your lamp approaches its life expectancy. (See pg 45 of KDF46-E3000/KDF50-E3000 user manual.
Finally, please post your findings as others may well benefit from your experience. Good luck!

Sure enough, after reseating the lamp, the red lamp light is on now. I just ordered a lamp. Thanks for the help.
