==========================================================

Hi,
Its weak Lamp symptoms. You will see lamp LED red if lamp is broken or ballast supply does not work. In this TV ballast try to fire up lamp and lamp consume more current then specific value so protection activates and turn off TV, usually TV turns On by itself again and green LED blinks, no picture and TV turns Off again and this cycle keeps going on.
I'm Sony TV tech and fixed many TVs with same problem. Replace Lamp XL-2200 under following part number..for KDF-E55A20
A1085447A LAMP BLOCK ASSY XL-2200U
Available in Sony Accessories Store for $200
Please buy Sony original lamp for TV safety and avoid aftermarket / cheaper lamps.
Let me know further query about TV, if any.
Thanks.

This is becauee of circuit issue.
There should be blown thnig on Circuit of TV.
Check its fuse , Diode and register transisotr.
But if you are not technical person of tv then you need dto call TV repairer .
Also you can try another power supply becasue some times voltagew fluctuation and earthing problem create problems.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.Have a blessed one!

Hi,
TV will show Lamp Light warning if lamp got broken or dead.
Symptoms of TV shows lamp is weak and will be replaced. Weak lamp consume more current than allowed ratings and causing activation of protection circuit that shuts off TV and TV turns on again itself, that is why no blinking red light.
Please replace lamp in your Sony KDF-E55A20 TV, lamp replacement procedure is easy and written in user manual, click Sony Support to download user manual copy, if required.
Always buy Sony original lamp for TV safety, Sony original lamp is available in Sony Accessories Store for $200 with following part number..

Hope this info will help you.
Thanks.

Power button


Sorry, I have to say it. If the bulb (LED) is shot it would have to be zero flashes :-) It's my weird sense of humour. After that I hope you'll forgive me and someone can give you some real help.
