Question about Sony KP-51HW40 51" Rear Projection Television

2 Answers

Screen gets darker.

When I turn the TV on, the picture seems fine. But after about 10 - 20 mins, the picture starts to get darker. And when I turn the TV on, the red light blinks about 4 times. Any suggestions?

The blinking light indicates there is a problem much like a check engine light in a car.

Unfortunatly this is an older TV CRT based and is problably only capable of 1080i HD resolution if your lucky. I would watch it til lthe TV dies then replace it. If its unwatcable then its tiem to replace this set. If a CRT is going bad then its time for a new TV finding new CRT's is just about impossibel these days.

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.

Picture seems to be alot darker than before. toshiba 62hm95


I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
