Question about Sony Grand WEGA KDP-57XBR2 57" Rear Projection Television

Big vertical tinted stripe on screen

A very annoying problem has cropped up with my otherwise wonderful TV: major tinted vertical stripes across my screen. Note that the screen should be black here:


The middle stripe has a greenish hue, and the blue is stronger to the left of the stripe. It is most obvious when displaying darker colors, and seems to wash out with more saturated images. It is present with all input modes but doesn't appear to be "burned in". The problem developed suddenly - I only noticed it today and it's very obvious. Is this salvageable?

    The problem eventually resolved itself. Interestingly enough, the bands shifted slowly to the left until they worked themselves off the screen and didn't come back. I believe it was the blue tube that was going wonky. There was nothing on the lens, and nothing wrong with the projection mirror. I suspect it was something with the video circuit itself (dust maybe?), but for now I'm crossing my fingers and hoping it doesn't come back. Thanks for helping!

Need more information:
Can you isolate which color is causing the banding?
Is there something ON the lense itself?
Is the projection mirror broken or bent?

52" Mitsubishi projection TV has stripes


Depends on exact model number; if a WD-52525 or something very similar pitch it---they are falling apart and have all kinds of troubles.

Google the full model number with "problems" to see what issues the set has like a hundred bad surface mounted caps etc.

deight, your set is going into total vertical collapse, either the vertical IC is failing or some support component to the vertical circuit is failing, should not be an expensive repair, hope this helps, BMW Rider

Most likely a bad formatter board, which plugs in vertically on the signal board.

Vertical Stripes on My Mitsubishi WS-65809 Projection TV


ADAM,

YOU NEED TO ADJUST THE SCREEN VOLTAGES TO BALANCE IT OUT. YOU CAN DO IT YOUSELF. HERE IS A WEBSITE. PLEASE READ THROUGH IT ALL. ITS FOR RED TINT OR LINES, BUT ITS USE IS FOR THE SAME PROBLEM AND COLORS. HOPFULLY, ON A LITTLE ADJUSTMENT IS ALL IT NEEDS.
