<p>HI,
We have a Sony LCD KDF55E2000 bought in 2006. The screen turns completely green for a few seconds and then returns to normal.
Does anyone know if this calls for a new bulb or is it something else?
My web search has suggested a new bulb. It also has said to unplug and replug all of the cables (which we will tonight).
Thanks for any input.</p>
<p>If the screen is completely green it means the red and blue lcds are completely blocking the light for a few seconds, and the green lcd is letting every pixel through.</p>
<p>This cannot be the light bulb, which can only shine a white color, and has no control over the lcds.</p>
<p>How often does it do this?</p>
<p>If the optical block that contains the lcds is going bad, I see a new TV in your future, a repair will probably cost more than the tv is worth. It might even cost more than a new tv, considering you can get a 55" LCD 1080P flatscreen for well under $700 now.</p>
<p>drad, this is what I have been thinking ( a new TV) as I tend to psychic this way–knowing things before they actually happen.
The green has been showing up just every so often the last few nights and does not last long–about 4 seconds each time.
What I will do tonight is watch some normal tv and then some taped and see what is going on.
I so appreciate you response and will post more tomorrow. Hope you will advise!</p>
<p>We had that problem–put in a new bulb which was easy to do.
But you may want to upgrade your TV anyways–Black Friday is almost here! My D just got a new TV and I’m fairly jealous with all the new technology that is built in.</p>
<p>gouf, was yours green? Our picture gradually turned darker and a new bulb took care of that.</p>
<p>Yes, green. At the time (after internet research) we decided to chance replacing the bulb not really knowing if that would work but it did. Simple to replace.</p>
<p>Thanks. Good to know for future reference.</p>

<p>Apparently there is a known problem with these sets that Sony resolved by extending the warranty, but for a 2006 you would be out of luck. The problem was with the optical block, not the lamp though.</p>
<p>If the OP’s issue is with the optical block as described on that site, this tv is toast.</p>
<p>I have a hard time seeing how this particular problem could be the lamp. It produces one color of light, white, which goes through a beam splitter which splits it into 3 beams. Each beam then goes through a different LCD, which do the colors - one for red, green, and blue. The beams are then recombined to make the picture. From what I found googling around replacing the optical block was about a $1500 repair.</p>
<p>I don’t see how the screen turning completely green could be caused by a white light. Seems to me the problem has to be in the LCDs.</p>
<p>Bulbs for this tv only cost $32 or so on Amazon, around $100 if you replace the whole light assembly. So I guess you could give it a try for not too much.</p>
<p>I think it is a waste of money though, and would use this as an opportunity to upgrade to a 65" or so. 
</p>
<p>But that’s just me…</p>
<p>We watched about 90 minutes last night. Some regular and some taped. NOTHING! You guys are magic. Not once did it die to green and then come back to normal.
I am wondering if it is/was our Comcast box (had found that as a possibility on the web).
The nights it was doing this I was watching taped shows.
In any event, if it starts up again, we will try to change the bulb–from Amazon-- and cross our fingers. We are planning to move in a few years and I would really like to wait and see what space we will have at that point. But if we do buy one soon I have no doubt one of the kids would take the new one if it did not work for us:).
I love all the great info given here. Thanks!
I do suspect, notrichenough, that it is what you are saying. When it does it, it fades to green about 6 times in 30 minutes. Then it stops and is fine.</p>
<p>I don’t think I have had a television repaired since maybe around 1959. ;)</p>
<p>It is much easier and cheaper now (and an upgrade opportunity) to just buy a new one.</p>
