Question about Televison & Video
I have a hitachi 42hds52a plasma tv and when you try to turn it on it just makes a clicking sound then powers down. I know this is done automatically to protect the rest of the tv but what can i do to make it work over all. What would lead to this problem and what is needed to be replaced? A certain part perhaps?

This happens to me about every two months. I unplug the TV wait 30 seconds and it comes back on. I hope that works for you - it's a much cheaper solution:-)

TV's always make a clicking sound as the Main Power relay turns
on. If you are asking why it then doesn't turn on, it can be many
things. The processor monitors a number of circuits and if
something is amiss, it turns off. The most common failure is the
high-voltage circuit and if the set is any where near 10 years old, I'd
plan on replacing the flyback transformer as well as anything else it
damaged while failing.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope Ya Fix It!

I wish to tell the world about the simple cheap fix for your plasma! . Please let me know if I helped. I have a 50" Plasma that deicded after a year it didn't want to turn on anymore. It just blinked red LED. Which made me see red! It took me a year to find this inexpesive fix I hope this information will be helpful to you.... These are spendy items and none of us were thinking that after a year (seems like a scam to me) the TV just won't turn on anymore.... Then they say your no longer covered under warranty or you are and they send you to some repair shop 1-2 hours away and always and I mean always tells you the part is on back order.
Lukster is right it is a power supply problem. However you don't need a new board nor do you need to pay someone a ridiculouse abount of money to fix this. I fixed mine for 40 cents.
You more than likey have bad capacitors.
Unplug the TV from power. Remove the back cover. (some models require a star srewdriver) You power supply board is right in the center. A bad cap is bulgded or raised. A good one is flat. caps have an X on the top of them. More than likely you will see a bulding or just straight raised edges on the X on the top of the caps. Cap 3300uf 10v is the ones you are looking for. Once you find them replace them with 3300uf 16v caps. If one cap is not raised replace it anyway. These caps need to be a higher voltage that why the tend to pop. 16V is plenty, don't go any higher in voltage than that.
The caps need to be soldered on. You have 2 options do it yourself or unplug all the wire harness from the board then unscrew the board take your power board (dont forget your new caps) down to a pc repair or tv repair and have them solder them on for you. It will take less than 10 minutes. I do recommend putting the board in an anti static bag. You can buy these caps at radio shack or buy them on ebay.
After you get it repaired replace your board plug all power supply wire harness back onto the board (I recommend numbering the wires as you remove them), replace the back panel cover. Plug her in and fire her up. and BAM it works. then turn it on and off a few times in complete amazement at how simple and inexspensive this was to do. Then get angry cause your repeated calls to tech support was wasted breath.
