I have an RCA 53 in. rear projection television. It was working fine one day. Then later that night, I pushed the power button and nothing happened. I unplugged it, then plugged it back in. It made a couple of clicks. So it sounds like its getting power. I'm thinking on/off relay may be bad. Where can one find parts if this is the solution?

You have bad switches inside the tv. When a switch gets stuck nothing else will work including the remote. In other words, the microprocessor can take only one command at a time. Replace all the switches at one time to avoid trouble later.
That's because somehow the lightening caused a fault in the power board. Ypu can try an unplug for 2 hrs and then reconnect and start again If that dosn't work you will require intevention to replace the power supply
as per your statement
there is a loose contact in power supply section of your tv.
it is 1oo% sure that allthe parts are ok as
tv runs ok when it comes on.
but you will have to call tech. as without knowing technology it is dangerous to open tv due to high voltage.
This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set!
If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains).
Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day.
