Are you comfortable working with the high voltage innards of a plasma TV, including the use of a Multimeter, Soldering iron or gun, and electrical safety? If so, you will have to inspect the insides and look first at basic items such as the fuses, but continue diagnostics from there to all components, using care not to electrocute yourself. If you are not comfortable with such a thing, then professional repair or replacement of the unit is recommended. LCD televisions do not have such high voltage driver issues and do not suffer from burn in like plasma screens do, plus use substantially less electricity.

In either case, the symptoms you describe tend to come from dirty line power, so the acquisition of a UPS (Uninterruptible Power Supply) that will perform Automatic Voltage Regulation is highly recommended to scrub the A/C current and swap to battery if things get to a level that would potentially damage the TV. This kind of investment can increase the life of A/V equipment by twice or more.

I've replaced every board on the samsung plasma and still clicks


What do you mean by clicks? Plasma televisions are hot cathode ray, there is thermal expansion that takes place due to heat.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time; especially to Plasma TVs.

50PW350 won't turn on


There are no user serviceable parts on these flat panel tvs.
Use your warranty if available. This is why buying the extended warranty on expensive electronics is a good policy.
Find a nearby electronics repair shop and get it checked over.

mcdevito75 here, Hello Deirdre, the first thing to do is to let the ebay seller you won these items from know your haveing a problem with any money owed due to a non-verify number, this way the seller who you won the items from knows you intend to pay for them. You can contact the seller whom you won the items from by clicking on my ebay at the top of any ebay page then with the drop down menu click on won, once at the page of items you won, next to the item you won click the option on the far right sde of the item title, in the drop down menu click on contact seller. Once you have contacted the seller with your problem, then call ebay at 1-800-701-3229 you can also call paypal at 1-877-672-9725 or 1-402-935-7733 or 1-888-221-1161 and see about fixing any problems with your account.
