Sony KDF-E50A10/4 dark picture

So you do have a picture? Albeit dark blue? Then its the source and/or video connection that is probably the problem

Try to download the repair manual to your set from internet. It has all the details. It is very difficult to include all illustrations about it here by this window.

Hello hmt86,

Welcome and thank you for using FixYa!

This is the backlight bulbs or the inverter board that powers them. Both will need tested, hopefully only the inverter board will need replaced.


Have a great evening!

Yes, its time to replace lamp in tv.
Lamp replacement is easy and procedure would be written in user manual.
Thanks.

Ur tv might need the picture bulb replace,how long this tv had it bulb been replaced?

Adjust video settings:

1. Press Wega Gate
2. Select Settings
3. Highlight Video
4. Press + to select
5. Adjust/increase the brightness.
6. Press Wega gate to exit.

If picture is still dark, you need to replace the lamp again. Sony recommends that you replace the lamp:

1. After approximately 8,000 hours of use.
2. When the screen becomes dark or the color becomes unusual.
3. When the lamp indicator on the front of the TV flashes.
   

Bulbs are expensive. Hundreds of dollars. First check your settings in your menu. Start by setting the contrast to a brighter setting. If all of your settings are messed up there will be a reset for your picture settings in your menu. If this doesn't solve your issue call your local audio/video installer for help.

Yes, this is common in Sony's when the lamp begins to fail. You may even see a small sulfar looking burn on the lens of the lamp (that is what causes the pic to go dimmer). Remember not to touch the lens when replacing new lamp.

What you need is the owners manual my friend. In here it will show you where to get to the lamp and how to change the lamp. Go to http://esupport.sony.com/US/perl/model-documents.pl?mdl=KDF55WF655&LOC=3
to get a free copy of the OWNERS manual. Page 16 tells you how to do this. Good Luck

try a lamp first, through best buy their about $150 -250. If that fails it might be the optic block assembly which is about $1,000, and i just recently had replaced, and the picture is as bright and clear as when i got it two and half years ago
