Hi:
This is due to low voltage getting to the Inverter board or the Inverter board on the bad side is not lighting the lamps. Usually bad capacitors or the power supply and the inverter will cause this symptom. You may want to replace both inverters boards on this model, new models have one inverter board for both sides of the backlight.

    My samsung LNT4671F does the same thing except on the right half, but it starts to work fine after about 20 minutes from power on. Is this kind of problem common? It has progressively got worse over the course of the last 3-4 months, will it eventually just go out or worsen over time? Are these caps associated with the known cap issue samsung acknowledges that cause clicking and repeated power on/off switching that they fix for free? If not, what is an average cost to repair the power supply and the inverter?

Hello, my parents bought a Samsung LNT4671F 46-Inch 1080p 120Hz LCD TV about two years ago unfortunately me and my brother cracked the screen about 3 months after we have not fixed it. Me and my brother...


It is beyond any reasonable repair---screen unit is called a display panel and the most expensive part in the set---cost of this would (just the part) be more than a brand new set.

Let it go, some people do sell sets damaged like this on EBAY for parts.....

Samsung LCD 46 inch half of the screen is darker than the other half.


Hi, while fixing another persons lcd tv i used lower rated power supply to try to fire up the tv ( picture-no sound) the bulbs ( actually cold cathode fluorescent ) lit up but only halfway. So sounds like the power supply for your backlight has gotten weak. You may try a workaround I've used on personal equipment, try turning down brightness on tv-this may,if your lucky, even out the brightness. hope this helped. Prodzilla

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?


No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.
