Check the U24 (CPU reset IC) on the "A" board. It may be burned. If you have a DVM (voltmeter) check for 3.3V across SW1 connections near this device. If you don't have 3.3V, U24 is bad. This part is not available from Sony. The TV may work if you just remove U24 from the board. I posted this fix on Agoraquest also, you can read more there (I'm "Roundabout" on that forum). Hope that helps.

This means that the lamp for the tv has gone out. This is replaceable but it is in the $200-300 range plus labor. If it is under 2 years old it should still be covered under warranty for this problem.

Samsung TX-R3080WH, tv is less than 2 years old and the picture is too dark to see it. some channels, you can "make out" a picture, but for the most part, channels are black. but you can still hear it.


not sure about this model but it sounds like the backlight has gone out. You can call samsung at 1-800-samsung and they may be able to help or give you the # of the nearest service center.

Picture went black


The backlight inverter board may have gone out, or the power supply for the inverter may have gone out. If it is two years old, you should look at the power supply first for bad capacitors.

Sounds like the back light is out, and the unit needs servicing. You can check this by shining a flashlight close to the surface, and if some image is seen, the the back light is the cause. Else the LCD driver is gone.

Monitor is on but disply id black


Having a similar problem.  When I turn my monitor on, the picture tries to come on, but then goes black.  After several times, I may get lucky and the picture will hold.  Is my monitor about ready to give up the ghost?  Mine is a few years old as well.

Black square in the middle of the picture


You have the set configured to display "text 1 or Text 2" in the closed captioning menu. You will need to turn closed captioning off to get rid of this box.
