Blue streak on right side of screen

I just replaced the bulb in a Panasonic PT-AE700U and now a blue streak is very noticeable on the upper right side of the screen. The blue streak had appeared only days before I replaced the bulb so I thought a new bulb would correct the problem. The old bulb had 3195 hrs on it so I thought this was symptom of an old bulb. Any advice would be helpful.

    If you display a blank (white) screen, you may find the tint is distorted in bars from left to right. They call this problem "vertical banding". Or it may show that only one of the primary lcd colors is the problem. Vertical banding can a common problem that can be significantly reduced by tweaking the service menu options. It can often be reduced to the point that its only noticeable if you're specifically trying to find it. The only way to reduce it further is to replace the lcd panel(s). If, on the white screen, the left side is bluish, but the rest of the screen seems to be fine, the problem may instead be a bad polarizer. Polarizers are a relatively cheap fix, running in the neighborhood of $100 per unit (usually only one polarizer will be bad if only a single color is off). Hope this helps, I have no further info at this time, other than a suggestion of trying to contact someone at Panasonic for further information. (All info I stated is simply what I've gathered from various, seemingly credible, sources while investigating this problem myself. Mine bleeds blue on the far left and also has the vertical banding issue throughout the 'screen'.

    I have the same problem. My bulb has only 1094 hours on it. The blue streak is more pronounced at the top right and is not symetrical. I thought it may be dirt, dust or a poor connection so I did a R&R with the bulb assy and it only slightly changed the blue area. It did not diminish it. This blue problem affects the right side of the picture during many darker or blue scenes while watching TV...it makes a sparkeling or blue tinted area more pronounced.

Hi ErnieN008

If there is no LED's flashing or even lighting up for that matter , then it could just be the fuse on the Poersupplyboard that has gone.

You can replace this fuse by opening up the top cover and looking for the board with the AC inlet on it.

If the problem however still exists , you will have to replace the powersupply.

your color calibration may be off. see if you can set the red green and blue settings all to "0" and see if that works. may want to refer to your manual and see how you can do that and also see if there is a auto calibration

as long as the bulb number crossreferences with an aftermarket bulb, it will work fine. Panasonic does not manufacture the bulbs, they just stick the name on it!

MY PT-AE700U LCD PROJECTOR HAS A BLUE HAZE RUNNING VERTICALLY ON THE LEFT HALF OF THE PICTURE.


Open the upper cover remove screw back side of the projector
Remove LCD connector and clean with soft cloth and fix it again.
close the upper cover and then POWER ON if the problem exist then the blue LCD is faulty and need to be replaced.
(very carefully because the ribbon cables and connector of the LCD is very senstive)

neither. the light filter on the blue lcd panel is fried due to excessive dust and heat. you may need to replace the entire optical engine if you cannot get the individual part.

Permanent blue hue down one side of screen PT ae700 panasonic replaced lamp made no differance tried compressed air no change please help


if the discoloration has a sharp pixelated edge, it may be the lcd panel. if the edge blends, it's the light filter (polarizer) that is burnt from excessive heat and dust. either one needs replacing.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
