    I HAVE A SONY KDF-E50A10 THAT HAS A BLURRED AND FUZZY PICTURE WITH BRIGHT COLORS THAT OCCURS INTERMITTANTLY FROM CLEAR PICTURE TO FUZZY. WHAT IS THE PROBLEM WITH THE TV? IT IS A 3LCD REAR PROJECTION TV.

  • PB Noack Aug 31, 2010

    How does one re-align the lenses? I there a written procedure for doing this? If so, where may I obtain a copy of it? What degree of technical difficulty is it to re-align the LCD's?

    Is it possible the color block is dirty?

The optical engine  - the set of lenses and prisms that merge the image from the 3 lcd's and project it on the screen no longer works correctly - the lenses are out of focus.
The only thing you can do is to take the engine out and try to realign the lenses. If the lenses are deformed or you can't push them back into place then the engine is dead, and the tv with it - it will cost you more than $800 to replace them.

    The lenses are from plastic and are just pressed in place in the casing of the optical engine - from the heat of the bulb they expand and in rate cases just pop out of the recess in which they should be located. Usually when they expand from the heat the recesses hold them in place so they deform - when they cool they remain deformed and the image gets fuzzy. To fix them if they aren't deformed is to press them back in their correct position.



    No, the LCD can't be dirty - if they would be like that then the image would be dull, darkened and with spots, the opposite of what it is now.

  • PB Noack Aug 31, 2010

    How difficult is it to get at the plastic lenses? Where are they located? Is there a written procedure to show me how to perform the correction if it indeed can be performed?

  • Azrael SRL Sep 01, 2010

    To access the optical engine is quite easy, all you need is a screwdriver to remove the screws that attach it to the LCD block and the base of the tv.
    No, no written procedure. Actually the optical engine is supposed to be an unserviceable unit - if it fails for whatever reason it should be completely replaced - so no procedure at all is available. You must act just using your common sense, after looking at the damage.

Hi.

Problem is likely a defective a defective LCD display. A faulty light engine and a defective video controller board may cause similar problems.

If problem is the light engine or the LCD panel, then the TV is usually considered beyond repair.

This is a repair that will in any case result expensive, requiring long hours testing and parts that are not cheap. The only way you can have this repaired at an affordable cost is by calling Sony and having the TV repaired at manufacturer low price.

Hi,
Green picture is caused by the light engine (the projection part of tv) failing and has to be replaced. Sony has extended the warranty on some models so you might be in lick. Contact them with model and serial number they can help setup repair if you qualify. If it is not covered it can cost between $1000-2000 to fix, which is way too much.

Verticle lines following the color spectrum across the screen.


Had Sony KDF-E50A10 that had the same line problems after 16 months. Was fine at lunch time and when got home from work and turned it on, they were the lines. Want over $800 to fix it. Told me it was the B-Board assembly. Sony was no help. They have exteneded the warrenty on another part that works along with the B-Board but not just the B-Board itself, so probably not any more Sonys. I'm going with LCD now.
