The light bulb is most likely burning out or lamp hours have set a certain hours and lamp will need to be replaced or lamp hours need to be reset.

I push my power switch and nothing happens. the


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.

There is no picture or sound


check your lamp, if lamp has been replaced then re-set the lamp timer, if you hear a clicking or buzzing and no picture is probable that you could have a ballast problem. I'd check the lamp first though.

RCA HD61LPW42 - no picture


I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.

if it doesn't then the Trying a new lamp first is reccommended.
After all, you will need another lamp eventually.
Samsung Parts

http://www.samsungparts.com/
model HLM507W as two different lamp replacement part. the LAMP for my TV was BP960224A. the replacement lamp listed on the Samsung site is BP960224C which was replaced by BP960224J. the difference according to my supplier is that A part has a brown power coupling and the J part has a black power coupling. hope this helps someone in the future. The couplings are different and a black LAMP coupling will not fit a brown TV coupling.

Replacement is simple, getting the right bulb is tougher. Make sure the TV is unplugged and the lamp has cooled. Looking at the TV from the back there is a lamp cover on the lower right. Remove the single screw, remove the door. There are two screws holding the lamp in, loosen these. Then flip the black plastic handle up at the bottom of the lamp assembly and pull the lamp assembly out.

Note the brand of the buld and the color of the connector (black or brown) and then call to order your parts from Samsung's parts reseller

With set off...mute + 1 + 8 + 2 + power.
Arrow down to "Options" push enter.
Lamp reset and lamp hours should be in there.
Power off 2 minutes or until fan kicks off to exit.
