Question about Hitachi UltraVision CineForm 55VG825 55" HDTV

1 Answer

Projection tv has a red '' aura'' / red blurry spot in the center

When the tv is turned on and the screen is black or dark, you can notice a large red spot type ''aura'' almost looks like a light red blurry cloud...But when the picture is white or bright color, you can't really see anything of the spot, the picture looks ok..
Wondering if their may be a bulb out in the tv causing this and if it's worth fixing.

I have a light red hot spot just right and above center, any idea how to repair?


You have to take front projection screen off of tv. When you have taken screen off, turn on tv and observe light coming from the three crts. Look into the face of each crt and you will notice some contamination inside face of one of the crts. Most crts are sealed, so youll have to replace the burnt crt causing spot on picture.

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV


You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

Poor picture no color


OUCH! LARGE DARK SPOT IN CENTER IS NOT GOOD FOR PROJECTION TV. YOU BURNT THE TUBES. THE LOSS OF COLOR IS THE ROOT CAUSE SOUNDS LIKE A DEFLECTION CIRCUIT PROBLEM. THE TIMING FEEDBACK IS USED TO SYNC THE COLOR CIRCUIT. IF THE TUBES LIGHT WITHOUT DEFLECTION THEY BURN THE CENTER PHOSPHOR COATING INSIDE.

TV issue


There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.

Dark spots on tv


I have the same TV, and I was getting the black spots on my screen as well. It is dust settling on the bottom mirror. Yoiu can call Mitsubishi and spend 150-200 on getting it cleaned, or you can do like I did and take the front panel off and the 10 screws around the edge on the back of the black plastic border around the screen. Then lift up gently and have someone hold the screen for you and gently dust the bottom mirror. I did this by myself, but it would be wise to have 2 people do it.

Red spot when screen is black


Your light engine will need to be replaced as you have a LCD panel failure. Here is the link to the part number for the model 50V500 if you have the 50V500A it has a different part number. http://www.partstore.com/ProductDetail.aspx?ProductSKU=8286849&ProductType=PART&ModelID=374014
