If you have the original remote for this TV on the pip menu (left side slider on remote all the way up) there is a pip off button. If you unplug the unit long enough it should go back to normal. If you go into demo mode and then exit mode you will again be out of the pip. With out the original remote you cannot easily turn pip off.

Unplug the set and give it a shot. Nothing to lose at this point. Considering the age of the set, it's not worth getting it fixed anyway.

If you have a cell phone or wireless internet this may cause interference. If you have any of these close them out and see if it still does the sound.

If you open up the back and locate hte fluback transformer (part with large red wire coming out of the top), you should see two controls on that tramsformer. One is the screen control which will control the overall brightness of the picture and the other (bottom I think) is a focus control. It may be marked on the transformer itself as well. Turn that control slightly while watching the set. This should resolve the problem.

I would suggest to measure the 200 volt B+ at the CRT socket. If that voltage is found to be low, disconnect the socket from the CRT and measure again. If the voltage reading returns to normal you may have a defective CTR.
Also check for open or defective diode on flyback transformer for the 200 vdc source.
I would also suggest to take all the necessary precautions since you are working in a very high voltage area.
Good Luck.

Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.

You have connected the speakers to the audio line out sockets. These are meant for connection to an amplifier and are not suitable for what you are attempting. If there are no connections on the back of the TV specifically for loudspeakers then you will need to add an amplifier or Home cinema reciever.
