Samsung LN46B650 tv is darker on one side

hi Elle924.
this is all i could find out.
What kind of panel do you have - a LED or CCFL one? If it's CCFL then check the inverter board. The main board might be fine (changing the brightness settings changes the signal to the inverter board) but if the inverter board is faulty somewhere then the problem you described may be caused by it
or try this forum.

The 60 K hours is bogus---Average life on a OEM lamp is 2,000 hours or two years average---if you got four or more years you were lucky.

To your problem---

How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

If no settings have been changed it means your backlight is dimming. This is a common issue with LCD TV's however it usually doesn't happen this soon. The best thing to slow down the dimming process is to lower your contrast settings, however what you really should do is calibrate your television either professionally or by using a calibration DVD or Blu-Ray with color filters.

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

Normally when your picture starts to get darker or dimmer it usually means that the lamp is almost out, your are able to go to a page called discount-merchant.com they have good prices on tv lamps and tv parts also and they also help you with questions you may have.

Most sets have electronic service adjustments. Contact manufacture for nearest service center.

The adjustment is on the transformer = it is labeled "screen"
for screen voltage.If the tv is working normally, you should not
have to adjust at all.My recommendation is to get the tv fixed,
not "mask" the problem with the screen adjust. The brightness
limiter circuit is suspect or the transformer itself. Any product
that has an electric AC cord attached is potentially dangerous
not to mention the physical removal / reinstall of the back.....T.

Please rate this solution....................

try to open your tv and you can find the flyback ,in flyback you can see the screen and focus to adjust.use and try to rotate the screen,it control the brightness of your unit

Caps in high voltage needs changing, needs tech
