I have a 50' Sony Grand Wega red bar on top of screen


Well this is an LCD projection TV and it sounds like one of the polarizer filter has gotten out of place so you are seeing at the top of your screen the unfiltered image of the LCD panel.
Will need to go into a shop to get repaired. Call and get an estimate of repair. Actually shouldn't be too bad of a repair cost.
Blessings,
A/V Media Tech Guy

My Sony Grand Wega LCD TV currently has a large blue spot on the left side of the screen when powered on. I have changed the lamp, but this did not solve the problem. Could this be caused by bad component...


Hi,
I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

I have a Sony KDFE50A10 50 inch HDTV When I turn it on for it has the lines verticle on it it takes a few minutes and then clears...tv or cable?


Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or vertical lines.You will need to replace the light engine.God bless you!

WEGA KF50WE610 50 no red color


Hello ml707,

This could be a problem with the red video driver circuitry or the signal processor. The $1000.00 price range is rather steep, I say this because you can buy one of these sets for $1400.00 used from:
http://www.amazon.com/gp/offer-listing/B0000E3DQE/ref=dp_olp_2/104-4293379-3459139

It is possible (the $1000.00 repair price) depending on if the lens is at fault along with other factors, Take into mind this is an LCD projection TV and the lens in this case is to focus the picture from the LCD screen onto the projection screen

I hope this helps,

Faint red lines in a curved arch like pattern


Guys I did this myself real easy. Just don't turn the corresponding screw too far. Only need to adjust it until the lines go away. Do it on a darker screen so the lines are more visible. I did the red 2 years ago and the green 6months before that. The blue lines are coming on my screen now and I've fixed it in 10 minutes. The TV is amazing.
