Dark line down the middle of my flat screen tv


Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.

The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.

DARK PIC


Most likely, you need to replace the Lamp in your set. It's easy to do; the replacement lamp will even come with simple instructions on how to do it.

There is a rare, rare possibility that the Lamp is OK and that the Optic Engine is causing the dim picture; however, of the hundreds of slimline projection sets I've worked on, I can count those rare instances on one hand.

Get you a lamp.

Blue dots on LCD screen


You will most likely need to replace the panel. You will have to contact Sony and they will send a Factory Trained Technician to your home to replace it. Since you are not on Factory Warranty this repair will cost you. You may find it cheaper just to replace the television.

Sony tv problems


Ya, The service tech came and said it was the Ballast (power to the lamp). We also had to have the lamp replaced because the ballast was ruining the lamp.
Cost - $80.00 for first visit with diagnoses, Ballast $120.00, Lamp $162.00 plus another $80.00 labor.
Now I plan to call him back because there are a lot of blue spots on the lower left part of the screen, and the picture is darker than before.
He showed me one spot before he left and said it was dust on the "LCD" inside the TV and that it would probably work itself out. He said we probably didn't see it before because the screen was too dark. BULLS***! It's darker now than it ever has been. The brightness is set as high as it can go with out distorting the picture quality.
Good luck!

Dark screen since new


Wow only 10 then major work, hum. First if pic is:Split screen picture with one half darker than the other half. "Deep Field Imager" is set to the demo mode, press the "video" button repeatedly to cycle through the video settings until Deep Field Imager is accessed and then change the setting from demo to "on" or "off" depending on preference. Also u can try:1. Dark blue raster with faint movement in the background, suspect the FMT PCB part # 934C153001 . Also1. May be intermittent. Remove and reseat the DVI cable between the Chassis and Optical engine 2. Removing and reseating the DVI cable does not resolve, replace the Optical Engine part # 938P015020 Hope this helps Tom!!
