Question about Sony Grand WEGA KDF55E2000 55" Projection HDTV

1 Answer

I replaced the lamp last year... just this week a Yellow hue has taken over the middle of the screen. It can only be seen when the picture has a white image. It's very difficult to watch hockey with yellow ice. Please help. I tried a new lamp and made sure the connection compartment area was free of dust. same problem. It almost appears to be like the old picture tubs with a magnet next to it.

My Sony Grand WEGA KFE50A10 50 in. LCD projection TV has a yellow hue over the picture except for the centre where there is a clear circle of perfect picture. I have replaced the lamp but this has made no...


It is the optical block causing the problem. Sony has had recalls on a lot of the LCD rear projection tv's made over the last 6 to 7 years. The cost of the optical block is around 800.00. Due to the cost, I would check with Sony to see if it qualifies as a recall situation.
I hope this helps,

I replaced the lamp on a Panasonic PT-LC80U thinking this will solve the yellow appereance, but it did work, it seems that there are not blues in the image. What Can I Do to solve the problem?


here are some probable causes..
This appears to be an older model (over 5 years old) and LCD projectors turn yellow with age. It's just what they do
However, if you are projecting a computer signal or a component signal, a short in the blue signal of the cable can cast yellow hues over your image. The hue will cover the entire image as if you are viewing the image "through rose (or in this case, lemon) colored glasses" so to speak. That's an easy fix.

Harder fixes: the blue LCD panel is weaking and/or gone bad.

If you have a round yellowish spot in the middle of your screen, the diffuser has been overheated and is "burnt".

Convergence and lamp problems?


Well I hate to be the bearer of bad news but besides the convergence issues you have a bad red picture tube. Us techs refer to your problem as a 'floating grid' in the red picture tube. More bad news is that the tube is no longer availible. The only solution is to have a professional remove the red tube assembly and ship it off for rebuild. A company called Video Display does this work reasonably and I've sent several to them with great results. It takes about three weeks and the whole repair is very spendy, around $400 to $500. Sorry for the bad news.

Picture is distorted


Is your TV near anything magnetic ? This causes picture issues. If the thing is a tube TV then you can fix this fault with a magnet. Call 0845 20 20 118 for help

Yellow spot in center of screen


I have recently developed the same yellow spot problem on my Sony KDF-E50A10  50" LCD television...a large yellow circular hue that takes up the bottom center of the picture and is especially noticeable against a white background.  It has been diagnosed as the optical block (light engine) and without an extended warranty Sony refuses to assist with the repair cost.  Repair was estimated at $1,100 plus tax and travel fees to my home.  So you see, it is not only a Hitachi problem.  You would think they could build something that would last more than two years considering the initial cost of over two grand for the TV !

Kf-42610 blue hue and blue dots on screen


Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
