Lamp on no picture or sound

There is no sound or picture but the lamp is on. None of the buttons work. After unplugging it and letting it set same problem. It always turns the lamp on and the lamp light flashes and then stops like it should. The remote affects the led on the tv it flashes when buttons are pushed.

    1. I have the same problem with my 46in. DLP SAMSUNG purchase in 06. The cause is from a digital board which if repaired it will cost you in neighbor of $600.00 to $700.00 from a TV repair shop.

    Same issue, The lamp is on but no sound or picture. The lamp stays on unless I unplug the tv. Then the lamp led light flashes for about 20 secs then goes off. None of the buttons on the remote works. When you press any of them, the "timer" led light flashes. Why would the circut board go bad for no reason?

How do i fix a non responsive tv set?


Do the ballast first. That should get the picture back. The main board controls everything else.

The tv came on then the screen went black but there was still sound for a sec. Now the green light keeps blinking and the tv won't turn


Unplug the tv for 5 minutes, then try this. Keep holding the VOL+ and CH- buttons down while you plug the tv cord back into the wall ac outlet till you get sound and picture for a second or two. You should be able to turn the tv on and off with the power button now. Next turn the power button off and unplug the tv for a few seconds and then plug it back in and turn the power button back on. Watch the screen and see if the sound and picture comes on, best to check in a dark room to see better, if sound stays on and picture comes on a few seconds and back off you have a bad CCFL backlight lamp in the LCD panel. This tv hads (10) CCFL lamps part # RLMPLA029WJN1 cost $15.93 at www.partstore.com or $19.49 at www.encompassparts.com in it and if one is burned out it will not let the tv picture be powered on till it is replaced. To check and replace the CCFL lamp you will have to unplug the ac cord from the tv back and remove 10 screws holding the back on. With back removed unplug the wire plug on the power button circuit at top left side of the black LCD screen trim, remove 4 screws holding the top of black trim, lay speakers off it, and release trim clips, (4) at top and (2) at bottom with a flat screw driver, and lower the trim to unclip the LED circuit board at bottom left side on the trim. With trim removed, at top of LCD panel remove the (2) PC ribbon wire clips with thumb nail by lifting up on it to release the flat PC ribbon wire. Lay the tv back on a soft pillow with screen up, and look on the LCD panel front for and remove the (10) silver screws 1/2" long with an arrow mark beside them. Do not remove any gold colored screws or any without marks. The LCD panel screen can now be lifted off, lift the backlight plastic thin sheeting and thick sheet off to see the CCFL lamps. Plug the ac cord back into the power supply inverter circuit board and plug the power button plug wire back in its circuit board on the LCD black trim panel, and power the tv on while looking at the CCFL lamps. If the lamp is dim or burned out, take the (2) white plastic covers off the ends of the lamps with a flat screw driver and unclip the lamp to replace it, Check the lamp socket part # QSOCFA003WJZZ by putting a good lamp in it and if it lights up the sockets are good and the bad lamp was the problem. If all the CCFL lamps do not light up, unclip the top lamps and move them to differant sockets to the center and the center lamps to the top, if the lamps do not light up, then it is a bad power supply inverter circuit board the ac cord plugs into, part # RUNTKA448WJQZ , cost about $160.00 for new one or less if you buy a used one on www.ebay.com , replace it and the tv should work ok then.

Replaced lamp, sound but no picture


Try unplugging the set for 5 minutes and then replug it in, allow 70 seconds for it to boot up (LED stops blinking). See if it works then. If not press the input/device button and menu button at the same time read a 2 digit code (blinking led) flashes first # short pause and the flashes 2nd #. This will be necissary to determine your cause. Most common besides lamp is power supply caps that cause intermittant operation.

>>The first thing to do is a system reset using the recessed button on the front panel.
>>If that does not work, unplug the set and let it sit overnight
SYSTEM RESET button with a pointed item like the end point of a paperclip
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
