My Tv won't turn on...

When I turn the power on, it makes several clicking noises like it wants to turn on, but then I hear a few more than usual and it fails to turn on...Almost like it clicks itself off again. The red power light blinks twice then remains a solid red and repeats the blinks... I've tried unpluging and repluging everything... I doubt the repair will be cost effective...can someone pls advise how to fix this problem? Thanks!

Re: My Tv won't turn on...

The two blink code "could" mean a problem in the power supply. I believe a 3 blink code means the 3.3 Volt Supply Is bad on the power Board. I would price the new 42" LCD TV's vs repair costs before proceeding.

How to reset tv

hi Tracie,
is the set making a clicking noise?
is the power light flashing on the front?
or no power light at all just dead?
if the set is just dead, just put your ear to the back vents can you hear like a very faint screaming noise and can you smell and burning in the vent?
if so it just could be capacitors on the power board.
if its clicking the that will need a service kit on the power supply board.
if the power led is flashing then you will need to count how many flashers from start to finish when you first turn set on.
hope this helps.

TV won't turn on. I hear a clicking noise near the power supply. I have no picture or sound

This is usually and most likely caused by the power inverter/board. There are capacitors and other components that can burn out and will cause the power not to be transfered correctly

My 40' vivo tv has turned off and won't turn back on but the red stand by light is on??

If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

46 inch Samsung HD clicks but won't turn on. First notice several weeks ago when using remote to turn on tv, it would click a few times and come on. Over a period of time, it would click for longer...

A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

Clicking noises before TV turns on.

The clicking noise is coming from the power supply relay. Is makes this sound when the TV is usually turned on or off but has become faulty. It will only get worse over time usually until the TV will no longer turn on anymore. You need to replace the power supply in order to fix the TV.

Samsung 46 clicks takes 45 sec for picture

Hi my name is Eric,
I hope I can help you with your issue ,
The TV not starting properly you should hear the tone noise (bleep bleep) not a ticking noise or no sound .
Great that its under warranty
These Samsung LCDs have problems with the power supply capacitors going bad, a servicer will charge between $200 and $450 to repair it replacing either the capacitors or the whole board.
here is a DIY (do it yourself) solution:
It could be just a few bad capacitors on the power supply, if you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on to.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
with the back removed you will usually see two circuit boards the upper one is the power supply, it has a few capacitors on it (cylindrical standing straight up soldered in mark on the sides with the positive/negative sides and MF and Volts values)
Samsung uses mostly 1000Mfd at 16Volts rating capacitors, they cost about $1 each (680mfd will also work fine)
usually I replace about four of them (or all the bulged on top ones) .
The power board and back unscrew with a medium philips screwdriver, if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
Im am posting a photo of some swollen caps on a board so you know what they look like;
best of luck to you
Hope this helps, if it has solved your issue please click accept
But if you have more questions please respond and I will reply asap
