I have a ultravision 50v500 and it has a blue blob in the middle of screen. I have just changed the bulb with hardly any change in the blob. I also had the light engine changed approx 2 years ago.


That is caused by excess heat possibly due to poor air circulation/blocked filters.
It is damage to the LCD panels. It won't get any better, just worse.
So look for another Blue LCD panel and someone who is experienced to fit it.

50 INCH rear projection LCD Gettign blue spots on screen forming a circle?


A discolored Blob or blotchy pattern usually in the center of the screen. the problem is becoming all too common with Hitachi projection sets. What happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far-gone except to replace the light engine-at a cost that makes it not worth repair. if the damage is minimal than to reduce further damage, the air filter should be replaced. The Light engine needs to be removed in order to replace the air filter

Have it checked by a tech it's worth the service call to know for sure

spherical or oval shaped light starting in the center of your picture is an indication of an led backlit tv.. probably a hitachi. solution, replace light engine..ps no garuntees not with led backlit sets.. was bad idea to begin with. when the leds start going they start at the center and branch out.

I have a hitachi 50 in rear projection tv and i am getting a yellow circle through out the middle of the screen what do you think that is and how do i fix it?


I looked back and see your talking about a crt type. My bad. A small yellow spot is most likely dirt or a bug in the blue optics. Tale the front off the set and with the tv on look down into the lenses. If you see a blob of dirt or a bug this is your trouble. Be careful not to move the blue tube but take the lens assembly off and clean the surfaces. There are four screw that hold just the lens assembly. The other screws shouldn't be touched. It will need alignment otherwise.

Blue streak at bottem of screen


Hello,

You have the classic "blue blobs," In most of Sony's rear projection LCD's, the Optical block is bad. Manufacturer's defect. The blue panel inside of the optical block starts de-laminating (due to heat from the lamp). This is a very common problem. I have changed about 70-80 optical blocks myself over the course of about 4 years.

There is no other fix but to replace the optical block. Unfortunately, it will get worse, and will probably develop "stars," or stuck pixels, as well. You can call Sony and try to get some assistance, but the extended warranty on these sets has recently expired.

Hope this helps you in some way...

To all that are experiencing the blue blob. This is result of poor maintenance. Projectors must be kept clean on all air intakes. This is to help you all understand the failure cause. Usally not worth repairing.
