You capacitors IN your power supply need to be changed out. If you have knowledge of electronical repair, it should be somewhat easy to moderate challenge. OR< you can get a new power supply. Seems to happen in many of the new tv's these days

LCD TV no power but standby light on solid

The standby light means the tv is plug into the wall and getting power. A power surge can wipe out a tv and still leave the power light on.

Changhong model ud42yc5500 ua TV. Why doesn't it turn on?

If "Standby light goes off as should" find out what has caused the power supply to fail. Could be a simple as an open fuse

Lcd tv light flashing but no picture or sound

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

Nec pxt-42sx1b won't turn on. We press the on button on the remote and the stand by light turns from red to blue but then goes back to standby.

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.3_26_2012_10_39_22_pm.jpg

No picture but powers up

there is a problem on your power supply section take out the switching power supply from the unit and test whether it operates normally..if it does the problem probably on your high voltage section specially the circuits backlight...replace them.

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.
