My TV show good picture but had no sound for 3days sound came back for a couple of hour than went silent no sound. What seen to be the problem?


Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. Surf the site with patience.

TV has power, but picture or sound will not come on.


It sounds like something in the set has failed. These newer TV's have shut down circuits that won't let the set come on if there is a short or excessive voltage somewhere in the set. Most failures in TV's occur at the moment the set is turned on.

No picture and no sound


simply unplugging the TV and turning it back on if started to work.
if it doesn't then the Trying a new lamp first is reccommended.
After all, you will need another lamp eventually.

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.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

Clicking Noise, Jumpy Sound, No Picture


The SMPS (switch mode power supply) is a bit tricky in this unit. Failures in the SMPS can give false impressions of what's actually happening with regard to the symptoms. You'll need to ESR the caps in the SMPS first. C525 250v/10uf is a good place to start. It sounds like the B+ voltages are present by the noise you're describing and that would indicate that the regulator circuit is probably okay. Next I'd check things like the HOT (horizontal output transistor) for short. NOTE: If you don't have an ESR meter the job is nearly impossible. Electrolytic caps don't always show any outward signs of damage. Only by checking their equivelent series resistance are you able to determine if a lytic is the culprit.
