My samsung 42'' plasma 4264 is two yrs old and now just makes a clicking sound , but blue led light still shows power...my kids said it made a popping sound then went off

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.
　
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 top.
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

Have your Y-Substain Board Replaced also have the power supply checked for shorts. I suspect that the Y-substain board is the proble.

Please leave comment..Thx

Well ..... I just fix my clicking sound ( no power or blue light) problem by soldering loos connection on power board .
Take back cower off ........and plug power cord in.......... watch for little sparks .......... solder it back good.......... it works

I would suspect power supply. This model is older than 2 years though. I have one with a bad power board. Cost is about $260.00. to $300.00.

Something went bad into the secondary stage of the power supply. the chirping is a protection function, tries to start but a short stops it. Needs professional attention.
