Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

I have a somsong hd tv and when i push the power button the tv want come on no picture. I hear a click sound every twenty seconds but no power seem to be getting to the picture tube tv mod# LNS4041DX


Based on your message, your TV has a bad high voltage section. Probably the HOT (Horizontal Output Transistor) failed or shorted and it either killed the high voltage or there's a current fluctuation; that is why the picture went, but there's a clicking sound. Then, when you turned it off or unplugged it the protection circuit remained active.

Once the high voltage fluctuates, that's the time the TV would create a clicking sound.

There's a 75% probability it will require a high voltage and horizontal deflection amplifier overhaul. The normal cost of that should be less than $200 if you take it in.

For this problem, I would suggest to contact a repair tech and have him take care of the problem.

Good luck!

No picture, no sound, power light steady green


First: Check the power outlet. Check it with a good lamp so you know you are getting power to the set.
Secondly: Check the power cord. Wiggle it around the molded ends to make sure it is not open inside the molded portion of the plugs.

Thirdly: If you know for sure the set is getting power and still no indication at all (you should be getting some little light on the front panel; standby indication) then there may be a fuse on the back panel or just inside the back cover (you will have to remove it; after unplugging the power cord) that needs replaced.

Fourthly: After all these checks if you are getting nothing, you may have some failure inside that is very serious. Normally we do not recommend serious repairs to a set over 4 years of age. This is because the set is likely to develop some other problem soon after the repair is made; further, the repairs are getting more expensive day by day while the price of new sets is coming down dramatically. Lastly, the new sets have better picture, longer lasting circuits and better features.

Hope this is a good solution for you.

thanks for your questions.

My Hitachi was doing the same thing. The culprit is a bad or intermittent 5V relay on the power supply board.

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.

Loud electrical sounds


It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.
