Question about Sony KDF-E55A20

1 Answer

I have a Sony Wega KDF-E55A20 rear projection LCD TV. The screen stays black when pressing the Power On button. When the Power on button is pressed, a GREEN blinking light (5th light in a row of 5) comes on and blinks about 58 times, along with an intermittent "popping static" noise. It then goes to a STEADY RED accompanied by the 2nd light in the row of 5, BLINKING RED. It continues like this until I unplug the power cord. It will do the same thing if I plug it back in an press the Power On button again. Anyone know what the problem is?

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

SOURCE: KDF-E60A20 Going on and off by itself..no blinking lights

it works!! First i took off the front panel. Just check your manual for instructions, very easy to do. If you do not have a manual just down load one from google.. The instruction are easy to follow. The screw they have you loosen with a alan wrench is attached to the plastic, so you do not have to worry about dropping it inside the tv. Removing the lamp was simple. once out you will notice on either side are two small mesh screens. One of mine was 80% blocked with dust, the other side was only 30-40% covered. I used a vacuum to remove the blockage, i did not want the dust and dirt to go inside the bulb. i then cleaned all around the lamp. Reinstalled, and we are go to go. The kids are happy and i am happier since my wife not be buying a new TV.
total cost of repair $.00
time required to fix, less than 15 minutes.

Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.

hope this helps.

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

SOURCE: my tv is blinking red in the power indicator 4 times on my KDS-50A2000

I had the same problem. Red LED blinking 4 times. This error means that one of the fans is NOT spinning! To check.... unplug the tv.... turn the TV around to a well lighted area so that you can see the fans in the back... plug the TV in and turn it on. Watch for the fans in the back... and see if they are spinning. If not... that is the reason why the TV will not turn on! In my case, the fan next to the lamp was stuck for some reason. I removed the the cover of the TV from the back... and cleaned the fan, made sure all connectors to it were properly connected... and viola! The TV is perfect again! Enjoy!

It is the lamp cover. There is a switch behind it and the post on the cover will slip off the switch. If this switch is not depressed, the tv will go off. No lamp light flashing or anything

My sony grand wega kdf e55a20 power light keeps blinking red. what can the problem be?


Red is an indication signal for power connectivity. Recent devices have two power functionalities. Using the remote control would turn off the display of images to power saver mode. A red power light imiting diode display is indication that requiring display of images is achievable by pressing on the display mode button once more. NOTES; Powering on the device may be achieved with the same function buttons as shutting down the entire Device to least communicate with the power supply circuity from outlet sources. The device is in power off mode ready for repower on with the remote control. Requesting the TV to shut down completely would require to press on the TV button firmly until power cuicuit are disbabled completely. Refer to the TV user guide to ascertain fucntionaility modes usual during operations. Goodluck
