Re: Sony KDF-E55A20 55 in. LCD... Problem red light...

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

No power or sound

the blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one

Hope this helped

Sony KDF-E42A10 rear projection TV. Won't turn on.

Start by changing the lamp. If you got 5 years out of the old one, count your blessings, most folks only get three. The lamp is designed to be replaced by the consumer. Ebay will carry a replacement for you or you can get it directly from They've got good prices. The lamp door is on the back. Its really easy, give it a shot.

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.

when your tv blanks out, turn off the tv and then it back on. below the power button usually flashes green light. does yours flash red? if so you need to count how many flashes. the number of flashes will help in resolving your problem. then google red flashing light sony and you will find what the red flashing lights mean.
