Question about Zenith P42W22B/H 42 in. Plasma Television
Thanks for using FixYa. High pitch/click sound is caused due to power supply. You'll need to open the back of the unit and check/test HOT (horizontal output transformer) and flyback, replace the part that has gone bad however, replacing both the parts at the same time is recommended. Also check the power supply board for any bad components.This is only recommended if you have electrical expertise which I think you have as it seems that you are repairing two TVs at the same time :-). Please accept the solution if the issue is resolved or post a comment for further assistance.

Do you get any sound? If not it is most likely a failed power supply board on the tv. Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will need to
contact a local TV repair person in your area. If you think it may
still be under warranty please contact the manufacturer to file an
RMA. If you happened to purchase the TV with a major credit card (not
a debit card) there is a good chance it may still be under the free
extended warranty most credit cards place on electronics. Please
contact your credit card company to inquire if they do this, and they
will be able to file the claim and get you a refund for the TV.
So sorry that I don't have better news but it is definitely a power issue internally.
