Yellow spot in middle of screen


Hi there,
We have the same exact problem with the same TV. We've only replaced the bulb once about a year ago. Don't know if it had anything to do with the fact that we now have a large yellow circle in the middle of our screen, which is about 7" round.
We only noticed the yellow mark about 4 months ago.
Hopefully someone will have a solution for us that doesn't cost an arm and a leg. Paid $2100 for this set and are a little disappointed.

Hitachi rear projection LCD with yellow blobs on screen


I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.

How do i fix or get rid of a green spot and a couple of purple spots on the tv screen?


Does your model end with a "5" as in PTnnLCX65? If so call the Panasonic call center to schedule service or find a servicer, they have a fix for colored spots on the 2005 MMDs ending with the number 5. The fix is being coverd under warranty.

Blue haze and dull yellow patches on screen


The light engine in your set has gone belly up. It is a very expensive repair. Good news is that on a whole bunch of models like yours Sony has extended the waranty on the light engine. Check with a local authorized Sony service center and give them the model & serial number and you might get a free ride. If I were a betting man I'd take odds on 'you're in luck'. LOL

Yellow spots are appearing in the upper right quadrant of the screen. After the set has been on for a couple of hours a second spot appears in nearly the dead center of the screen. This issue coincides...


Try the new lamp as indicated by the blink codes. That may resolve the problem. If not, the problem is in the "light engine" portion of the set which should be covered under warranty.
Keep us posted.

ZENITH E44W46 LCD HDTV


Its your light engine failing. It can cause different colored "spots or ovals" to appear in the black background.

My Zenith ( now LG ) E44W46 LCD had the engine replaced after only 10 months, and now 3 years later it is failing again. There is a lawsuit against LG for using defective engine assemblies in this particular model.

After much searching I located this number, 800.243.0000 and called from work this past Monday at 8:15 a.m. central time. I was blown away to actually have someone pick up and direct me to a rep who reassured me that LG was aware and has set up a department to handle claims.

I was issued a case number and told that I will be contacted by a rep from this "department" and they would replace the set. With what I don't know yet but I will post back after I get thier final answer and the details.
