On some models there is an electrolytic cap.near the relay that tends to short and cause your relay to trip.That may need replacing.

The power button on the tv is broken and i lost the remote


You can just try programming the remote with the Sharp codes they list in the instructions until you find the one that works. Follow the procedure for entering a code and try it. When you find the right one it will turn the set on when you hit the power button. The remote's instructions tell you to turn the set on to make finding the code easier (when the set shuts off you know you found the right one), but you can work without it.

27 inch tube tv won't stay on


You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.

My TV keeps shutting off


Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.
