My unit seems to work fine, except there is a dark shadow covering the right third of the projected image. Is this a sign that the bulb is going out?

The issue is not with the lamp, it is with the dust accumilating on the inside of the projector's lense elements. I know this because I opened up my Sony VPL-ES2 and took out one lense element at a time and cleaned off the accumalated dust off of all of them. There appears to be an accumalation of dust in the inside of the front lense also. Ehich has to be cleaned out... disassembly of the top of the front lense reveals the 3 elements that get dust on them also. HOPE THIS HELP ANYONE WITH THE SHADOW APPEARING ON ANY OF THE CORNERS OF THE PICTURE.

This is the light tunnel needing to be adjusted or replaced because is has collasped due to the heat given off by the lamp during the life of the projector.

If it is the lens you have other problems that would let it get that hot. Can't be sure, but I would first check the bulb to make sure it has not smoked. If so it must be replaced. When handling the bulb let it cool down or you can get severly burned. Never let your skin touch it or the oils on your skin can damage the bulb. I usually use a t-shirt or something to wrap it in while handling it or you could just wear cotton gloves.

I have a Toshiba 51h83. Everything works fine except there is an issue where the colors are slightly lighter on both the left and right sides of the screen.


this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)

let me know if that helps!

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine replacing the bulb will not solve your issue. Have a blessed one!

Panasonic PT-51HX41 rear projection tv showing shadow/double images.


Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?

Round shadows in picture


Sounds like the Bulb is almost out of life or a dustball or something is moving around inside the light compartment. Look in the instruction or user manual on replaceing bulb or opening bulb compartment or call Mits. for a service center in your area. Good Luck
